Toxicologists refer to the total amount of a chemical present in the tissues of an organism as

Zinaida [17]

A dense growth of plant life in a aquatic ecosystem which many animals living there die(due to lack of enough oxygen present in water) and the ecosystem gets completely disrupted.

Eutrophication excessive richness of nutrients in a lake or other body of water, frequently due to run-off from the land, which causes a dense growth of plant life.

how is the expression of sex linked genes both similar to and different from the expression of autosomal genes?

svet-max [94.6K]

Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents. Women recieve one X from the mother and the other from the father while men recievethe X from the mother and the Y from the father).

This will cause a difference in the expression of genes because women can become carriers of a certain disease while men either manifest it or don't (there are no carriers since the X chromossome is different than the Y)

In autosomal genes, the expression doesn't depend on the gender since the autosomal chromosomes contain genes that code for the same trait, and so the expression on autosomal genes in men and women are similar.

Which RNA sequence is produced using the DNA sequence AGC-TAC-ACT?

Natalka [10]

The RNA sequence is produced using the DNA sequence AGC-TAC-ACT is UCG-AUG-UGA.

<h3>WHAT IS TRANSCRIPTION:</h3>

Transcription is the process whereby a mRNA molecule is synthesized from DNA template.

During the process of transcription, the following applies:

Adenine in the DNA produces Uracil in mRNA
Thymine in the DNA produces Adenine in the mRNA
Cytosine in the DNA produces Guanine in the mRNA
Guanine in the DNA produces Cytosine in the mRNA.

Therefore, the RNA sequence is produced using the DNA sequence AGC-TAC-ACT is UCG-AUG-UGA.
