Using the data in the table above, which best explains how muscle cells and skin cells are adapted for our environment? question 2 options: muscle cells need more mitochondria than skin cells because skin cells require a cell wall. skin cells need more energy, so they have less mitochondria than muscle cells. muscle cells have more mitochondria than skin cells because the human body is made up of more muscle than skin. muscle cells need more energy, so they have more mitochondria than skin cells.

The right answer is D.

The mitochondrion is an important organelle in the cell, whether it is muscle or other. It represents the power plant of the cell (where the Krebs cycle and oxidative phosphorylation occur). Muscle cells need a lot of energy to function (contraction and relaxation), so it is quite logical to find more mitochondria in muscle cells than in skin cells, which have a simple role of coating.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
