Answer:
<u><em> oxygen in the solution will naturally diffuse into the cell.</em></u>
Explanation:
Cells require oxygen for cellular respiration to occur. When a cell is places in a solution having oxygen dissolved in it, The concentration of the oxygen outside the cell will be more as compared to the concentration of oxygen inside the cell. As a result, the cell will take up oxygen by the process of diffusion. Diffusion is the movement of particles from a higher concentration to a lower concentration along a concentration gradient.
Answer:
B. In the small intestine, carboxypeptidase attacks peptide bonds.
E. Pepsin causes the hydrolysis of some of the peptide bonds in proteins.
Explanation:
The digestion of protiens doesn't occur in mouth, it occurs at only 2 locations in GIT :
- In the stomach
- In the small intestine
Digestion of protiens start in stomach causing the stimulation of gatrin hormoone which stimulates the release of gastric juice containing HCl , Pepsinogen , Rennin (in infants). The pepsinogen is activated to pepsin by HCL and pepsin itslef, and cause hydrolysis of the peptide bonds in the protiens.
The remainder of protien digestion occurs in small intestine as a result of the action of enzymes including trypsin and peptidases. Carboxypeptidases attack the peptide bonds and result in cleavage.
Answer:
The correct answer is D. The bacteria must adjust to the nutrient content in the new medium, synthesizing necessary amino acids, growth factors, and enzymes.
Explanation:
As a bacteria enters a new medium it is not able to divide immediately because the environment of a new medium is different from the old medium. A new medium may contain a different and complex food source for which bacteria have to synthesize new enzymes and growth factors.
So initially bacteria remain in the log phase which shows that the bacteria is adjusting in its new medium and synthesizing necessary amino acids, growth factors, and enzymes required for their growth in the new medium.
Therefore the correct answer is D.
Answer: The main function of the pineal gland is to receive information about the state of the light-dark cycle from the environment and convey this information to produce and secrete the hormone melatonin.
