Answer:
erosion (if not im sorry cause im only 80% sure)
ANSWER:
okay so they were 100 hyenas and 20 died
so that makes it 100 - 20 = 80 , so there was 80 hyenas when 20 died
then 35 were born so 80 + 35 = 115
than 5 migrated INTO the population meaning 115 + 5 = 120
At the end of the year, there were 120 hyenas in the population.

Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
<u>N</u><u><em>atural selection acts on existing heritable variation</em></u>
Answer: Option C
<u>Explanation:</u>
Natural selection is a process that occurs in nature as a key to evolution. It also goes hand with the survival of the fittest. Nature always selects the best trait to survive or get accustomed to the surrounding by undergoing modifications.
It acts on the genotype of the existing generation and causes variation in the future generation. So the population over generations get to have acquired the variations in their body, structure so that it is adaptable to the surrounding.
