How would a mutation increase genetic variation?
Lena [83]

Answer:

DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.

The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production
natima [27]

Answer:

This question lacks options, the options are:

a) Negative primary production

b) Net primary production

c) Secondary production

d) Negative secondary production

e) Positive primary production

The correct answer is b.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.

Explanation:

Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).
