Explanation:
True, if sedimentary rock is exposed to energy from the sun at Earth's surface for a long enough time, it can melt into liquid rock and form igneous rock. No, igneous rock forms under Earth's outer layer due to energy from Earth's interior, but sedimentary rock is only at Earth's surface.
The answer is B. Stabilizing selection. Stabilizing selection is a type of natural selection. Stabilizing selection is the opposite of disruptive selection where extreme values of a trait are favored over intermediate values.

I think this is right......
Explanation:
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
Answer:
Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.
C. Polysaccharide
