Answer: ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.

Answer:
In the given case, the brain of the alien would be showing an enlarged region with surface grooves and folds. It is nothing but the cerebral cortex and mainly the neocortex. As the name suggests that it is the latest addition to the brain and is regarded to be originated by the process of evolution.
It is the main region of extraordinary cognitive tendencies like reasoning, thinking, analysis, and other things. As mentioned in the question, that alien is trained like astronauts on the Earth, thus, this neocortex would be certainly found in the brain of the alien.
Answer:
The correct answer is: D) the pivoting of the myosin head, which causes actin and myosin to slide relative to each other.
Explanation:
<u>Muscle contraction</u><u> occurs when the sarcomere is shortened.</u> The sarcomere is a structure composed of filaments: the thick ones are composed of myosin, and the thin ones are composed of actin. These two proteins interact with one another to make the sarcomere shorten and produce the contraction of the muscle.
Muscle, in its natural state, is not contracted. This is because <u>the binding sites on actin for the myosin heads are covered</u> by the proteins troponin and tropomyosin.
When the signal for muscle contraction arrives at the muscle, calcium ions are released from the sarcoplasmic reticulum and reach the sarcomere to reconfigure the complex formed by troponin and tropomyosin so <u>the binding site on the actin filament becomes exposed and the myosin head can attach to it.</u>
When an ATP molecule appears and binds to the myosin head, the latter separates from the actin-binding site and moves toward the next actin-binding site with the energy provided by the hydrolysis of this ATP molecule. This is what is called power stroke.
This keeps on happening until muscle contraction is no longer needed and calcium ions are reabsorbed, which will make troponin and tropomyosin cover the actin-binding sites once again.
