Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

Answer: Contractile vacuole of amoeba will shrink/contract when the organism is placed in sea water.
Contractile vacuole is a subcellular structure ( mainly found in protists) that is involved in the regulation of water quantity inside a cell.
As we know that water always flow from a hypotonic ( where solute concentration is less) to a hypertonic ( where solute concentration is more) solution. Sea water is a hypertonic solution as the concentration of salt is very high. Therefore, in this case, water will flow from contractile vacuole to outside of the organism.
Thus, contractile vacuole of amoeba will contract as it will lose water when placed in sea water.
Answer:
In nature, the oxygen element mainly occurs in gaseous form. While hydrogen is also formed of two atoms and is also a colorless, odorless gas just like oxygen. But hydrogen is generally found as water.
Explanation:
Oxygen and hydrogen are commonly diatomic molecules, not compounds. Hydrogen is the most abundant and light of all elements in the earth. Hydrogen reacts with oxygen to form water. Hydrogen too forms parts of many compounds such as acids, hydrocarbons in organic compounds and so on. About 10% by mass of human body is composed of hydrogen. Oxygen, as it already known is the elements responsible for the survival of living organisms. It forms about 65% of human body by mass.
