Answer:
My best guess would be that the barnacles coexisted with the oysters 100 mya.
Explanation:
Since similar oysters were found both in North America and Europe, we know that the oysters were roaming the earth when North America and Europe were once connected. And since barnacle fossils were found in the same layer, we know that they both coexisted 100 mya.
I do not know the options for this question, so this was my best guess.
The diagnostic term for beri/beri refers to <u>body weakness "weakness/weakness"</u> and is caused by the lack of thiamine (part of B complex: B-1) in the diet. Beri/beri typically attacks/damages the nerves and can further lead to loss of strength of muscles or worse case - paralysis.
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.
