Answer:
The correct answer is capsule
Explanation:
Capsule is the outer layer which is mainly made up of polysaccharide. It surrounds the cell wall of bacteria and is formed by many bacteria. Capsule help bacteria to adhere to the tissue surface which they infect.
Capsule of bacteria give virulence factor to the bacteria because they enhance the ability of bacteria to cause disease. Capsule protects bacteria from phagocytes and antibiotics. It covers the antigen present on the cell wall of bacteria which helps in protection of bacteria from immune cells. Therefore the correct answer is capsule.
Answer:
According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>
<u />
Thus the rate at which oxygen will move across the phospholipid bilayer will depend on the concentration or amount per mole of the oxygen molecule hitting the phopholipid at a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules increases.
Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid bilayer should also be maximized. the distances between the phopholipid and the vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law has been applied , and therefore maximum oxygen molecules can diffuse across.
