What must happen before meiosis can begin

Biology

<h2>Answer:</h2>

The replication of chromosome is followed by meiosis.

<h2>Explanation:</h2>

Before meiosis really starts, the DNA that is bundled into chromosomes must be completely duplicated. Past to replication, a cell of germ contains two duplicates of every chromosome, a maternal copy and a fatherly copy. The maternal and fatherly homologs depict the maternal and fatherly hereditary contribution to every cell and guarantee that every cell has a half hereditary make-up originating from each parent. These two chromosomes are autonomous yet fundamentally the same as and are named homologs of one another.  

DNA replication happens in a similar manner as it does during mitosis. After replication, the homologs are multiplied, and every chromosome presently has a homologous pair.

How do temperature and salinity affect deepwater currents?
WITCHER [35]

Answer: They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

The temperature and salinity has a major impact on water current of oceanic water. The warm water is usually less denser than colder water, so it remains at the surface of water body, whereas the colder water being more in density remain in a depth. The salinity of cold water is more than the warm water.

According to the above explanation, they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them is the correct explanation.
