Explain how current and oxygen content affect the biodiversity of streams and rivers

Biology
1 answer:
Eddi Din [679]3 years ago
8 0

Answer: The oxygen content at the source of the streams or rivers is higher as compared to the mouth of the river. Consequently, the organisms which require more oxygen tend to find at the source of the rivers whereas the organisms which require less oxygen tend to find at the mouth of the river.

Answer:

50% AA and 50% Aa

Explanation:

Punnet square is a tool used to examine the offspring's genotype result of a breeding experiment. We will need to put the genotype of a parent in the row, and other parents at the column. The parent is homozygous(AA) and heterozygous(Aa), the square will be:

                       AA

                 A            A

        A     AA          AA

Aa    a      Aa           Aa

When trying to determine the rate of cellular respiration (an aerobic process), why is oxygen measured and not carbon dioxide
dusya [7]

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.

Carbon dioxide:

Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.

There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).

Now, carbon dioxide is emitted as a byproduct in both types of respiration.

Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.

Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.

Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.
