Answer:
endocytosis
Explanation:
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
<span>During nitrification, ammonia is changed back into nitrate.</span>
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.
<span>When a cell is in a dynamic equilibrium with its environment, this means that the salt/water concentration inside the cell is equal to the salt/water concentration outside the cell. It is called an equilibrium because no transport of molecules is needed since the concentrations are already the same.</span>
Variation: When one of that species develops another trait or skill that the others do not have.
Adaptation: When a species changes in order to survive a certain place or survive a predator
