Answer:
Should be D. Breathable gases
Explanation:
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, and abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
Active transport is the process that would be used to transport calcium ions through the calcium pump.
Answer:
e. is under purifying selection
Explanation:
Purifying selection removes deleterious alleles that can arise through
random mutations
.
Mutations may or may not have consequences at the level of genetic expression depending on whether those mutations are synonymous or nonsynonymous. Synonymous mutations do not generate changes in the protein to be encoded while non-synonymous ones do.
Important genes for the development of the organism - such as those involved in the neural development- are very likely to be under purifying selection, eliminating individuals with deleterious alleles since those alleles (product of non-synonymous substitutions) do not allow the individuals to survive.
Answer:
In cellular respiration, stored chemical energy in organic molecules is converted to ATP molecules- 3)
The mitochondria is responsible for producing energy.
