sorry it's not an answer but hope this helps!
Answer:
C
Explanation:
Volcanic eruption spews volcanic ash into the atmosphere that lingers and blocks out sunlight for months. This causes photoautotrophs to decrease in population numbers due to the inability to photosynthesize. This will negatively affect the heterotrophs that depend on the autotrophs for energy.
Answer:
B
Explanation:
There are usually dominant and recessive alleles. The dominant alleles mask the expression of the recessive allele. Therefore, whenever an offspring has a dominant allele of a gene, it will be expressed whether in homozygous or heterozygous form.
Answer:
B
Explanation:
A limiting factor is an element whose abundance affects the growth and distribution of a population of a species in an environment. In this case, increasing the levels of Nitrogen in the environment increases the population size and vice versa.

Answer:
The. Two populations of sculpin lived on Lake Baikal, but a genetic change in one of the populations prevented them from crossing, thus creating a new species of sculpin.
B. The additional information I would use to test the hypotheses would be: 1) is there any species of fish similar to sculpin in the same lake? 2) what is the genetic change presented by the sculpins?
Explanation:
My hypothesis about sculpin fish states that sympathetic speciation has occurred. This speciation occurs when two populations of the same species can no longer promote crossings between them, thus creating an evolutionary process, which results in the creation of two distinct species, in the same habitat. I believe that this type of speciation is more common to happen in aquatic environments and in fish, since these environments present less physical barriers than the terrestrial environment. This usually occurs with the existence of genetic modifications within one of the populations. As a result, to test my hypothesis, I would need information about the existence of species similar to sculpin within the same lake, in addition to knowing what genetic differences between them would promote this type of speciation.
