Answer:
soil compaction causes floods because rainfall water cannot infiltrate into the soil.
Explanation:
The use of heavy machinery in an area for urbanization and other purposes have always caused a series of problems to the top soil. One of the major consequence of such activity is the compaction of soil. Soil compaction is caused when stress is applied into the soil and the density of soil increases as a result.
It has been found that soil compaction causes floods because rainfall water cannot infiltrate into the soil due to the compact density of soil. The water instead ends up in the surface which subsequently causes floods.
Seagrasses and mangroves improve water quality for corals and fish communities by slowing water movements and trapping nutrients and heavy metals.
<h3>What are wildlife sanctuaries?</h3>
Wildlife sanctuaries are secluded areas designed to protect animals who are endangered by human or envrionmental activities from being harmed.
Wildlife sanctuaries may be for terrestrial organisms or aquatic organisms.
Marine wildlife sanctuaries are designed to protect marine organisms as well as their from destructive forces of man and nature.
Coral reefs are endangered by acidification and increasing ocean temperatures as they hinder the growth of marine algae in coral reefs.
Seagrasses and mangroves increase the health of coral reefs by slowing down water movements and trapping heavy metals and nutrient rich runoff.
Therefore, Seagrasses and mangroves improve the water quality for corals and fish communities.

Explanation:
Answer:
The correct answer is - add a few bases for DNA polymerase
Explanation:
A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.
It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Under a microscope, chromatids look like little dots and chromosomes are lines.
