Which of the following is NOT a source of dissolved oxygen in the water?
lesantik [10]

Answer:

A. humans going underwater and exhaling

Explanation:

The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;

- Photosynthesis of aquatic plants: Oxygen is the waste product of the photosynthetic process carried out by green plants. Hence, when aquatic plants undergo photosynthesis, oxygen from them tend to dissolve into water.

- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water

- aeration as water moves over rocks and debris, and from wind and waves

However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen

raketka [301]

Answer:

This is an example of recessive epistasis.

Explanation:

Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.

Epistasis means "interruption" and refers to interactions between genes located in <em>different loci in the same chromosome</em>. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.

In recessive epistasis, the proportion is 9:3:4.
