the air in our lungs is measured in terms of lung volumes and lung capacities. volume measures the amount of air for one function, like such as inhalation or exhalation. capacity is any two or more volumes, for example, how much can be inhaled from the end of a maximal exhalation
if i'm wrong i'm really really sorry!!

These are called perennial plants. Annual plants go through their entire life process within a single year and stop existing, meaning they can't produce fruit every year.
Answer:
The correct option is D.
Explanation:
In the year 1952, two scientists, Hershey and Chase conducted a series of experiments that helped to establish the fact that DNA is a genetic material. The DNA is located inside the nucleus of living cells in form of chromosomes and its the determinant of traits that are found in living organisms. During protein synthesis, the information in the DNA molecule is encoded into an RNA molecule and this is used in the production of protein, thus, DNA actually directs all the happen in the living cells.
The major function of the contractile vacuole of amoeba is osmoregulation. The solute concentration found in the cell of amoeba's cytoplasm is more than the solute concentration in the freshwater that surround the external part of the organism, thus, water enter the cell through osmosis. The contractile vacuole collect the excess water and expel it through an opening in the cell membrane. By doing this, the contractile vacuole maintains the water balance in amoeba. This how the contractile vacuole normally operate.
In a situation where amoeba is placed in seawater, then water from the cell cytoplasm will rush out of amoeba cell, because of the higher salt content of the surrounding medium. The contractile vacuole will respond to the situation by increasing its contraction and pumping water out the cell in an accelerated manner, this will lead to the shrinking of the cell.
