Active transport is a process requiring energy in which a substance crosses the cell membrane.  When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of
ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.

Suggest one advantage and one disadvantage of<br>using a dichotomous key to identify something.​
prisoha [69]
Advantage: Dichotomous keys are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms. Disadvantage: Disadvantage of dichotomous keys is that if a single wrong decision is made at any juncture, a wrong identification will result. Sometimes it becomes obvious that an error has been made, and you can retrace your steps until you get back on the right track, but this is not always the case
