Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
<span><span>This
is because his hypothesis that an organism can pass on characteristics that it
has acquired during its lifetime to its offspring are not approved or </span>verified.
His hypothesis of the notion of inheritance of acquired traits was supplanted
by Mendelian genetics. Yet, because of the discovery of epigenetics and somatic
hypermutation interest in Lamarckism has continued.</span>
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
