Are humans likely affected by biomagnification? if so, which foods might be dangerous?

1 answer:

8 0

“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”

Human beings occupies the top place of most trophic level and we know that concentration of harmful chemicals increase as we go above the trophic level. Therefore human beings are most adversely affected by biological magnification.

Humans may also be affected due to the consumption of fish and shellfish.

Describe the genetic code and its relationship to polypeptides and proteins

konstantin123 [22]

The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.

What is the genetic code?

Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.

The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.

The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).

What happens to the effenciency of the exchange of oxygen in the human body at a high altitude

Daniel [21]

Answer:

The effiency decreases at higher altitudes

Explanation:

The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.
