Correct answer: B). With fewer contractions
The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.
But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.
Answer:
B) In anabolism, larger molecules are made from smaller molecules.
Explanation:
Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.
For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.
Option B is true regarding anabolism.
