Answer:
A) Natural selection favouring the recessive phenotype in the Alaskan populatrion.
Explanation:
- Natural selection allows only fitter traits to survive.
- Natural selection can change the frequency of alleles in a population.
- The natural selection will favor the allele which will have fitness greater and its frequency will gradually increase while the allele which will have lower fitness will gradually decrease in population.
- Here the recessive allele e must have a greater fitness so, natural selection favoured it resulting in its increased frequency.
The answer is B hope it helps.
PH is a measure of how acidic/basic water is. the range goes from 0 to 14 with 7 being neutral. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
They use evidences. Hope it helps
