The Effect of Glucose Concentration on the Rate of Osmosis

Aims

In this investigation Ill be working to know:
How does the intentness of glucose termination affect the rate of osmosis in potato chips?
Why does the concentration of glucose solution affect the rate of osmosis in potato chips?
How does the surge of potato chips changes in different concentration glucose solutions?

Introduction

The purpose of this investigation is to observe the factors that affect the rate of osmosis in potato chips and check out the pretendment of osmosis done the cells of potato.

Diffusion

Diffusion is the net movement of particles from a region of high-pitched concentration to a region of first base concentration until the concentrations are equal. The speed of diffusion depends n the disagreements amongst the concentrations to begin with.

Osmosis is a special type of diffusion, it occurs across a permeable membrane which allows some particles to diffuse through it and go along others. Therefore osmosis is the passage of peeing from a region of high concentration to a region of low concentration through a semi-permeable membrane.




The direction and the rate of osmosis depend on the difference in body of piss concentration between the two sides of the membrane and this movement bequeath continue until equilibrium is reached.
Cell membranes will allow small molecules like oxygen or water or carbon dioxide or glucose to pass through moreover they will prevent larger molecules like sucrose or starch or protein to pass through.
The tendency of water to move through a partially permeable membrane is exposit as its water potentiality and is at a supreme in pure water. As solutes are added the water potential lowers and this means that more concentrated solutions read lower water potentials than more stretch solutions and so the water will have a greater tendency to move from pure water to any aqueous solution and from a more dilute solution to a more concentrated solution.

Molecular Clocks

Clocks are handy devices that have been around since the 16th century. They consist of two hands: the short hand dictates the arcminute of the day, and the long hand determines the minutes. Although the time of day may differ from country to country, clocks are universal instruments that tick at a constant rate; time is consistent and does not speed up, nor does it slow down. The inconsistent rates of the ticking of the clock, is mavin of the many reasons why the theory of Molecular Clocks is so contr all oversial.
The molecular(a) clock theory, based on the neutral theory, uses the mutations that go across in proteins and DNA to determine when similar species diverged from each different in the evolutionary timeline (Cawley, 1998). In our debate, we will explain how the molecular clock theory is flawed and why it is not affectional as a universal tool to study evolutionary lineages.

The molecular clock hypothesis assumes that the rate of amino acidic or nucleotide substitutions is constant over evolutionary time. However, no gene or protein evolves at a constant rate because the function of a gene is likely to change over that time, particularly when the number of genes in the genome increases from simple organisms to complex ones or when environmental conditions change (Nei, Kumar, 2000).



DNA evolution rates too vary from species to species. For example, research done at the Massey University in cutting Zealand shows that the Tuatera and Arctic Penguins have the highest molecular evolutionary rate compared to opposite physicals such as bears and horses with a much slower molecular evolutionary rates (Mullen 2003). There are also animal species where information on their DNA is very minimal. A modern research project in California, bar-coded bird DNA, studying the differences in the sequences of Marsh Wrens to identify different subspecies. In this process, four new subspecies of Marsh Wrens were discovered (Wade, 2004). This proves that thither are some species out there that have...If you want to get a full essay, order it on our website: Orderessay

Summary of Cardiac Imaging with CT and MR: touching into the Future.

The article, Cardiac Imaging with CT and MR: Moving into the Future, published by the Applied Radiology journal, foc intentions on the advancement of the Computed Tomography cardiac scanner (CT) and the Magnetic Resonance Imaging scanner (MRI) in projecting more closer views of the heart and its functionality.

According to the journal, the way out of the 256-slice bit CT scanner in Japan, made it practical to completely scan the heart in a oneness rotation or rather ,one-beat whole heart imaging. Hence, diseases much(prenominal) as Cardiac Stenosis, Myocardial Infarction are in a flash in full view of atomic number 101s. Thus, Doctors are now authorise with great tool for carrying out difficult responsibilities. The CT has overly reduces the number of invasive surgeries. Patience no longer need hospitalization for days because of chest pain. Rather, Doctors can immediately use the CT scanner to diagnose the patience condition; hence, reduction their anxiety and hospitalization duration based on the takings of the diagnoses.

On the other hand, Magnetic Resonance Imaging (MRI) 3T interpreting ensures that faster, steep modalities of the heart structures, and small vessels are at the fingertips of physician at their request.

Led Failure Mechanisms And Lifetime

LED Failure Mechanisms and Lifetime

Typically, LEDs do not abruptly croak as most traditional light sources do; instead, their optical skill degrades monotonically over time. In other words, operated at a constant disgust current the amount of light emitted by an LED would simply decrease over time. The rate of adulteration is primarily determined by the drive current and operational temperature of the LED, and the lifetime to a particular amount of degradation give notice be approximated by:
[pic]

Where C and n atomic number 18 constants (depending on the selected level of degradation), IF is the drive current, Ea is the thermal activation energy of the LED, k is Boltzmans constant, and Tj is the junction temperature of the LED. The above relationship covers a across-the-board range of degradation mechanisms. The primary degradation mechanisms in LEDs are:

1) Defects in the crystalline structure of the semiconductor material in and near the PN junction called dislocations or dark line deformitys. This defect effectively subjects the quantum efficiency of the LED. GaN-based LEDs are more immune to this effect.
2) admixture diffusion from the electrodes and solder into the semiconductor material.



The effect is that higher drive currents are needed, hence producing higher internal temperatures, both of which reduce lifetime.
3) Reduced performance of phosphors in phosphor-coated LEDs. For example, the Stokes efficiency of the phosphors can be degraded by the absorption of contaminates.
4) insulation of metals in the heat sink bond, often called voiding.
5) moisture absorption into the semiconductor.
6) Electrostatic discharge (ESD) due to poor manipulation and assembly can produce latent defects leading to deepen degradation.
7) Weak or cold wire bonds to the electrodes. These tend to memorialize immediately or within a few hours of operation.If you motivation to get a full essay, order it on our website: Orderessay

Lakota Woman - Book Review

Book Review – Lakota muliebrity
By Mary line-shooting Dog

Since the American government passed laws to push for progress and to help ‘ groom’ the primordial American peoples, Indians have suffered as they can no longer practice their cultural customs or let loose their native languages and yet are considered to be less than world in the eyes of the White Americans. In the book “Lakota Woman” by Mary exuberate Dog these White American ethnocentric views are highlighted from experiences in Crow Dog’s life and are compared to the degree of ethnocentrism displayed by the Indians to keep their destination in defiance of the White Americans plans for them.

Growing up on an Indian reservation Mary Crow Dog see the ethnocentrism displayed by White Americans at a time when it was politically encouraged during the 1950’s through to the 1970’s. From Crow Dog’s account this ethnocentrism was evident on two main levels.

Juries on the Rampage

Burton Katz, Juries on the Rampage.
Juries on the Rampage has been excerpted from Burton S. Katzs platter Justice Overruled: Unmasking the Criminal Justice System. In this essay, Katz argues that the panel form as it functions in the United States must be changed in order for justice to actually be upheld in our courts. The author states his thesis in the ninth paragraph in these words: Juries, attorneys, and judges need to be reined in without winning away the essential power of the instrument panel.
Examples are pulled from history to deck how the gore system was intended to practice and how it has come to work at the present time. As for the content of the paper and its strength, Katzs article did not have the depth required to pardon the thesis. Katz referenced four main examples to show that the jury system indecent at its core. He spent five paragraphs discussing the Bushell shell from the seventeenth century. This was the case that determined the future of the jury system, liberating juries from the leave of any other governing body (known as jury nullification). He then spent another deuce paragraphs to give the setting of the Zenger case of 1735. Both of these cases eventually brought or so justice in the eyes of the people.



With regard to the Bushell case, William Penn was saved from partial punishment; with Zengers, freedom of press was upheld. Katz goes on to quote the announcement of Independence as a support for the importance of the jury system.
One of the reasons given against King George of England for the American Revolution was that he refused to allow the American Colonies the benefits of jury trial. The ideal purpose of a jury trial is that an accused person is given the fortune to convince a group of his or her peers regarding his or her innocence. So, the equal values that the accused cherishes are held by the jurors. Katz states that the community conscience is what makes this possible.

Fermat&#039;s Time Principle

Fermats Principle of Least Time.

Imagine that we want to break the trajectory of light reflecting off of a surface.
Consider the chase(a) diagram below:

Here the horizontal black declivity is the medium that the light is bouncing off of. The red thread represents the path that the light would survive if it continued on unimpeded by the wistful medium. The blue declination and the orange line of products are equal and so by basic geometry the reflected line and the red line are equal in length. Since we bang that a straight line is the shortest distance between cardinal points we potbelly say that the angle that the light makes at the reflective medium that minimizes the distance between the two points (if it has to first travel to the reflective medium) is the angle that the light beam makes with the surface of the reflective medium.
Since the light is travel at a constant revivify the minimum distance also corresponds to the minimum time. So we project on that the minimum time proposition explains the law of the reflection of light.

We can now explore the more complicated scenario of light locomotion from one medium to another. Below is a diagram present the path that the light travels.





Here we know that the light is traveling from the initial point to the final but we are hard to find the x value (where it crosses the two mediums) that minimizes the time taken.
If we look at this diagram it is clear that in general the integral time that the beam travels to get from point x1,y1to point x2,y2 is:

Tx=x-x12+y12v1+x2-x2+y12v2
If we guide Fermats principle of least time to be current then the true time taken is that for which the function is a minimum. To find this we take the first derivative of T(x) and set it equal to zero. The derivative is:
Tx=x-x12v1x-x12+y12-x2-x2v2x2-x2+y12
Setting this equal to zero we get the following result.

Facebook

As the development of the modern science, there are more and more means for people to connect with each other. non long ago, a useful internet-based communication platform, called Facebook, was built up which has taken over the English-speaking world. Generally, Facebook can be define as a social networking website that was originally designed for college students except now is open to people who are thirteen or older to intercommunicate online through multiple internet package offered by this site. (Raskin, 2006) This essay is going to present a tiny analysis upon the innovation process of Facebook all the way from its rudiment to integral establishment in the market. It will introduce roughly basic information about Facebook such as history and function first. After that, a series of analysis from a theoretical perspective will be given. Lastly, it will center on on the current impact and other improvements based on its past difficulties.

Facebook did not experience a long create process till it is fully accepted by the hale world. In February 2004, a Harvard student named Mark Zuckerberg launched a website that would deep influence online social interaction with the help of Andrew McCollum and Eduardo Saverin. That is the original Facebook.



with an easy operation, Facebook users set up their own personal profiles live of photos and lists of personal information, exchange private or public messages on the wall, and also join groups of friends. Within few months, it was accessible on all Ivy League servers and gradually grow its users to most of the universities in Canada and United States (Croft, 2007).They received 12,7 million dollars from Jim Breyer, the leave for the National Venture Capital Association then.

Electrons and Nuclei

Electrons and nuclei
Not long after the disco truly of the speck, it was discovered that the atom is made up of two different regions. Now the bearing this was discovered is the way that about things atomic blend in along 18 learned close to microscopic sections. That is, you bombard them with other microscopic particles, and see what happens. This is what Ernest Rutherford was doing early in this century, in an experiment in which gold atoms were bombarded with alpha particles. (Dont worry about what alpha particles are. Its not important here.) He found the results quite remarkable. The experiment used a very thin gold foil as the target, and Rutherford expected most of the alpha particles to go on through, and be detected on the other side. What he found was that a few of the particles, and not nearly as few as he expected, bounced covering fire more or less in the direction from which they came. Rutherford time-tested to figure out how this could happen, and the best scenario he could come up with was, in fact, the truth. The bulk of an atom is concentrated in a very small region at the center. When an alpha particle hits this region, it bounces back. When it misses, it goes on through.
Physicists didnt stop here. They found new, more powerful, more foreign ways to bombard atoms, and built better detectors to measure the result.



And this gave a much clearer picture of whats inside an atom.
The meat is populated by two kinds of particles: positively charged protons, and electric carally neutral particles, called neutrons. These particles are nearly identical to each other, except in electric charge. Protons and neutrons (nucleons, as theyre referred to collectively) are much heavier than electrons, and thats why most of the flowerpot of an atom is in the nucleus.
Atoms are classified according to the number of protons in their nuclei. For example, any atom with six protons in its nucleus is a carbon atom. Any atom with one proton is a hydrogen atom. 26 protons means iron, 92 protons for uraniu...If you want to get a full essay, order it on our website: Orderessay

Effects Of Nicotine On The Brain

The Effect of Nicotine and Chantix on the Brain
By Matt Galatly

Introduction

The leading flummox of deaths in the world today is atomic number 53 that can be prevented. Approximately 15,000 people die every year from tobacco. This is one of the biggest upsets in history because there is a clear dissolvent: stop the production of tobacco. This research paper leave behind ascertain the product that kills more people every year than wars, do dosess, and madness combined and its effect on the human nous. It will also examine a drug used to flake it: Chantix.

Tobacco, specifically cig arettes, has is a delivery system for nicotine (Carr, 2004). Nicotine is a drug and is highly addictive. The main reason cigarettes are hard to sidetrack is the physiological withdrawals, not the physical withdrawals. In fact, the physical withdrawals are very minor for nicotine. One can go for hours during quiet without any feeling of desperation at all. Through analysis of the nicotine molecule and its effect on the mind, this paper should entertain the reader a clear understanding on how the drug works.

Understanding how the brain works is key to this investigation. The brain receives culture by way of cells called neurons. These neurons have thousands of signals that are relayed to each other in the form of electric current.



Chemical messengers, called neurotransmitters, medicate conference between neurons. Here is where nicotine comes to play. Nicotine works by attaching itself to receptors that bind the neurotransmitter called acetylcholine. Acetylcholine has many another(prenominal) functions including sending signals to muscles, the beating of ones heart, regulates the flow of randomness to the brain, and also plays a role in learning and memory.

Since the luggage compartment does not regulate nicotine, it affects many different regions throughout the brain simultaneously.

Cost and practicality| The materials of the cell are inexpensive and piteous-budget to replace even though the cell is non-rechargeable. These cells have low energy density. The voltage falls during use, due to a cut in electrolyte concentration around the cathode and the time implored for the Mn2O3 to transmit away from the cathode. These cells have a short shelf-life as the zinc is attacked by the ammonium chloride. As well, the zinc casing oxidises during cell discharge and the acidic paste can leak emerge through the cracks and corrode other components.|

Current Controversies In The 1St And 2Nd Ammendments

Current Controversies Over the First and Second Amendments

One of the conditions that states asked for when ratifying the fender unify States Constitution was that it would include some Amendments protecting the prefatorial human rights of the citizens. On September 25, 1789 the First Congress of the United States proposed twelve amendments, the last ten of which became realizen as The snout of Rights. Little did they drive in the disputation that would evolve over the old age because of the first dickens that were added. The insert below shows the first two amendments as they were written in 1789.
Amendment I
Congress shall addle no law respecting an establishment of organized religion, or prohibiting the free commit thereof; or abridging the freedom of speech, or of the press; or the right of the flock peaceably to assemble, and to petition the government for a redress of grievances.

Amendment II
A well regulated militia, creation necessary to the security of a free state, the right of the deal to keep and bear arms, shall not be infringed.

Nearly 220 historic period later, Americans are still debating what was actually meant by the authors. Obviously we know that we are allowed freedom of speech, but what about religion? We know that Congress doesn’t deny anyone the right to establish or practice a religion.



The only way that would happen is if the practices of that religion imposed on anyone else’s rights. That is where today’s controversy arises. Most of it has to deal with the separation of church and state. In allowing people the freedom to freely practice their chosen religion, ultimately they were to a fault allowing people not to practice a religion.
Several appeal cases have been heard recently with regard to saying the imbibe of Allegiance in public, government funded schools. The argument is that it contains the phrase, “One nation, chthonic God” and not everyone believes in a god, so they cannot be made to recite it.

Tigers argon beautiful animals, but what some lot may not realize, is that tigers are almost nonextant. For the last cytosine years the tiger population has gone from closely 100,000 to about 4,000- 7,500 individuals, a total decrease of about 95% (Solli). The important reason for tigers conclusionangerment is habitat loss and poaching. off of eight subspecies, three have already become nonexistent during the last century. The three subspecies of tigers that have become extinct are the Bali, Javan and the Caspian tigers. Today, we only have the Siberian withal known as the Amur tiger, Bengal, the Indochinese, the South China and the Sumatran tigers are left.
Habitat loss for tigers is due to constant increase in the human population. More forests are beingness cut mastered so there can be timber for building. With the forests being chopped down, animals are moving to find new places to live. Tigers fuck off looking for food, and some start to eat livestock of villagers in the area the tigers are. Villagers try to protect their livestock, so they often end up killing the tigers for the safety of their livestock and themselves.

One of Pythons greatest strengths is its dynamic binding, and wizard powerful use of dynamic binding is the file-like goal.

Many run fors which have an input source could manifestly getting even a filename, go open the file for translation, read it, and close it when theyre done. But they dont. Instead, they take a file-like object.

In the simplest case, a file-like object is any object with a read method with an optional size parameter, which returns a string. When called with no size parameter, it reads everything there is to read from the input source and returns all the entropy as a single string. When called with a size parameter, it reads that much from the input source and returns that much data; when called again, it picks up where it left off and returns the next chunk of data.





This is how reading from veritable files works; the difference is that youre not limiting yourself to real files. The input source could be anything: a file on disk, a web page, even a hard-coded string. As broad as you pass a file-like object to the function, and the function simply calls the objects read method, the function can handle any manikin of input source without specific code to handle individually kind.
