Answer:

An estuary can be defined as partially enclosed coastal body of the brackish water in which one or more than one  rivers flows into it.

It basically forms a transition zone between the river and maritime environments which is known as ecotone.

The salinity of the estuary depends on the location of the estuary. Salinity level in the estuary declines during the spring season and when the snow melts and the rain increases.

The level of the salinity increases during the time of summer because the level of evaporation increases.

Answer:

Salinity in an estuary varies according to one's location in the estuary, the daily tides, and the volume of fresh water flowing into the estuary. In estuaries, salinity levels are generally highest near the mouth of a river where the ocean water enters, and lowest upstream where freshwater flows in.

Salsk061 [2.6K]

Answer:

Since sexual reproduction requires two individuals, it allows intermingling of genes which is beneficial for the individuals as well as the entire species. The organisms produced by asexual reproduction are genetically identical to each other. ( I hope it helps )

What information can not be obtained from the sequence of a gene? view available hint(s) what information can not be obtained fr
olganol [36]

The right answer is A.

The methylation profile of DNA is not obtained when DNA sequencing is performed.

Methylation is a process that can occur in DNA especially at the cytosine level. And this has a very important role in gene expression as it is part of the epigenetic expression.

Gene methylation can induce or repress gene expression depending on the localization of methylated bases.
