Clausen and colleagues proposed two hypotheses to explain this variation within a species: (1) There are genetic differences between populations of plants found at different elevations. (2) The species has developmental flexibility and can assume tall or short growth forms, depending on local abiotic factors. If you had seeds from yarrow plants found at low and high elevations, what experiments would you perform to test these hypotheses
Answers
A possible experiment to test these hypotheses would be to plant the seeds at different elevations and verify the differences in these.
What is an experiment?This is a scientific procedure that aims at testing hypotheses or potential explanation for a phenomenon.

Are you more likely to observe evolution between the s0 and s1 or the s0 and f1 population? explain your reasoning
Answers
Bettween the s0 and s1 or the s0 and f1 population, evolution will be observe most likely in the population with less gene flow and higher rate of mutation.
What is evolution?Evolution refers to a series if gradual and cumulative and transferrable changes which occur in organisms that resulted in the formation of new species from existing species.
Factors affecting evolution include;
gene flow,the rate of mutation andnatural selection.When there is less gene flow between populations as well as higher rate of mutation, evolution of species will be most like likely.
Therefore, between the s0 and s1 or the s0 and f1 population, evolution will be observe most likely in the population with less gene flow and higher rate if mutation.

Given what we know, we can confirm that by eating raw seafood, Billy runs the risk of contracting a parasitic infection.
What is a parasitic infection?Parasites are organisms that live inside another organism, this second organism is known as the host. The parasite steals nutrients from the host in order to survive, this often results in the death of the host if the parasite is not combated. These parasites are common amongst fish and are why Billy is at increased risk of parasitic infection by eating raw seafood.

Why is daily muscle strengthening activity not recommended?.
Answers
Daily muscle training is not recommended as it will lead to injury and fatigue.
Why does daily training lead to injury?Muscle training is an intense activity for your muscles. Training every day can cause injuries such as muscle tears or tendonitis from overusing the muscle in an intense manner for too long. For this reason, it is best to allow the muscle to rest at least one day before attempting to train again or undergoing intense activity.
Therefore, we can confirm that daily muscle training is not recommended as it will lead to injury and fatigue due to overusing the muscle in an intense manner.
