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

Solar Energy The use of solar energy is increasing throughout the world. Solar energy is used to make light‚ run computers and to conserve energy. Today we used fossil fuel to run factories and make electricity but little do the people know‚ one day we are going to run out of oil because it’s not a renewable source. Then what are we going to do ? We would have no other choice then to start using the sun for energy‚ so why not start now ? Solar energy is one of the world’s

Introduction Photosynthesis is a redox reaction which requires carbon dioxide‚ water and light to produce water and a 6-carbon sugar. The process of photosynthesis consists of two parts‚ a light reaction and a light-independent reaction. The method of changing light energy into chemical energy for the formation of NADPH and ATP is done through the light reactions. Light independent reactions use carbon dioxide and the products of light reactions (ATP and NADPH) to form compounds such as glucose

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

zes. Oxygen is measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis.

microscope is that it has a greater magnification‚ so you can see more detail about the organism. It would be preferable to use a light microscope when you want to see the cell in the act of moving or dividing. 2. Prokaryotic cells don’t have organelles like eukaryotic cells do. Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed
