Gas exchange is a biological process that is essential for the survival of an organism. The purpose of this process is to obtain oxygen from the environment (which is necessary for cellular respiration‚ and to dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first

1.There are three basic types of amino acids: 1) those with electrically charged side chains; 2) those with polar side chains; and 3) those with nonpolar side chains. A) True B) False2.All amino acids share a common “backbone”. Which chemical component (or components) is part of the backbone of an amino acid? A) An amino group (NH2) B) A carboxyl group (COOH) C) A hydrogen atom D) A central carbon atom that is commonly called an α-carbon atom E) All of the above3.Suppose that we link 100

Experiment 8.1 Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its

Significant Figures. Significant figures are the number of digits that we may use including or excluding the zeros that we may be given with any number or solution. There are many different rules in determining the proper number of significant figure in an answer. For example; “All zeros to the right of the decimal place and to the right of a non zero digit are consider significant”. So we were given the number 45.000‚ we know from the rule above that this figure has 5 significant figures because the zeros

about acid rain? I also should say the most important thing that scientists are doing in their labs. Where acid rain is most effects on which states and does it affect human when we swim in a really high acidic ocean. Acid rain is a mixture of water and gases that have a pH of 5 or lower and it is found in our atmosphere. Acid rain is made out of two main gases nitrogen dioxide which is formed from cars‚ and sulfur dioxide which is made from factories which burn coal. Acid rain or acid deposition

outer leafs. This is known as an adaptation‚ (leaves in the centre of a shrub are exposed to small amounts of light meaning they have little of stoma because if they had many then they would lose lots of water (by transpiration). Leafs must grow the correct amount of stoma (for gas exchange/water loss) to the light levels in an area (even if they are shaded) this gives them a balance. Method: 1. Obtain two leaves from a shrub‚ (One from the centre and one from the outer area) 2. Paint a thick
