Cell membranes are a bilayer make up of phospholipids‚ proteins‚ and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion‚ transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of the bilayer. Diffusion occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows

Respiration of Sugars by Yeast 1. PROBLEM STATEMENT: What is the effect of the type of sugar on the amount of carbon dioxide released by Yeast during aerobic respiration? 2. HYPOTHESIS: If the type of sugar is changed‚ the amount of carbon dioxide created will then increase because sugar is needed to for respiration so occur. If Fructose is added to the Yeast it will then respire the most Co2 because fructose is the largest sugar‚ its like using a hundred dollar bill instead of single dollars

arise when people think of population growth. It’s an issue we don’t usually think about‚ but one that Paul Ehrlich feels strongly about. He believes that it’s only a matter of time that we run out of food‚ and that humans will cease to survive. As seen in the first video‚ Ehrlich elucidates his point by repeating the word “finite” in the video. He refers to our planet and our resources as finite‚ and thusly juxtaposes the two to population growth‚ saying that population growth cannot increase without

Due to the small population size of North Atlantic right whales (~300 plus or minus 10%) and the low annual reproductive rate of about every five years‚ suggests that anthropogenic activities affecting mortality may be more prevalent for right whale population growth than for any other whale species. Ship strikes and fishing gear entanglements are considered the main factors contributing to reduced growth and recovery of the right whale population. Data collected from 1970 through 1999 indicates

Cell respiration takes place in the mitochondria of animals and in the cytoplasm of plants. The formula for aerobic cellular respiration is: c6H12O6+ 6O2→6CO2+6H2O Aerobic respiration occurs when oxygen is present‚ while anaerobic respiration occurs when
