able to receive the nutrient in the 1 cm cell and almost all of them in the 0.5 cm cell. This is caused due to the larger surface area to volume ratio as the cell size depends on the efficiency of the material to flow in and out through diffusion. Through diffusion‚ the organelles in the cell receive all the vitally needed nutrients to survive. If there is a big surface area to volume ratio such as 1:2‚ then this process will be delayed due to the sodium hydroxide having to cover a larger distance

Sir Sifton Clifford effectiveness in helping Canada How has Canada become the diverse populated country full of rich history and heritage It is today? All thanks to people like Sir Clifford Sifton who is one of the most important Canadian politicians from the late 19th century. This report will outline how Sifton contributed to the development of Canada`s cultural diversity by using strategic ideas‚ such as the immigration policy to help create the strong nation Canada is today. Sifton was a lawyer

ENGINEERING THERMODYNAMICS FOR YEAR I ELECTRICAL 1 INTRODUCTION AND THE FIRST LAW OF THERMODYNAMICS All living things depend on energy for survival‚ and modern civilizations will continue to thrive only if existing sources of energy can be developed to meet the growing demands. Energy exists in many forms‚ from the energy locked in the atoms of matter itself to the intense radiant energy emitted by the sun. Many sources of energy exist: many are known‚ some perhaps unknown; but when

1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

costs through Medicaid are linked to substance abuse. $1 out of $4 is spent on Medicare inpatient care. About 70 percent of state prison and jail inmates used drugs on a regular basis. One-third of state prison growth can be accounted to drug offenses. Since 1985 there has been an 80 percent increase in prison population. Addictions cause an economic burden on the United States that is two times that of diseases affecting the brain. Untreated substance addiction and abuse can have significant

Scientific Paper on Diffusion 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the

search for a drug dominates an individual’s life. An addict eventually develops tolerance‚ which forces the person to consume larger and larger doses of the drug to get the same effect. Addiction is a condition that results when a person ingests a substance (e.g.‚ alcohol‚ cocaine‚ nicotine) or engages activity (e.g.‚ gambling‚ sex‚ shopping) that can be pleasurable but the continued use/act of which becomes compulsive and interferes with ordinary life responsibilities‚ such as work‚ relationships‚

How is a cell’s membrane structure suited to its functions? Throughout the past century‚ scientists have been able to conduct more research on the structure of a cell membrane and understand its components and functions. The present agreed on model‚ created in 1972 by S. J. Singer and G. Nicolson‚ is called the fluid mosaic model. This model depicts that proteins (integral and peripheral) form a mosaic since they are floating in a fluid layer of phospholipids‚ which makes up the components of
