Troponin-tropomyosin molecules prevents a muscle contraction from occurring when the muscle is at rest.
<h3>What is
muscle contraction?</h3>
The activation of tension-producing regions within muscle cells results in muscular contraction. Because muscle tension can be created without changes in muscle length, such as when holding something heavy in the same position, muscle contraction does not always imply muscle shortening in physiology. Muscle relaxation, or the return of the muscular fibers to their low tension-generating state, occurs after a muscle contraction has finished.
Both length and tension can be used to characterize muscle contractions. If the muscle tension varies but the muscle length doesn't, the muscle contraction is said to be isometric. A muscle contraction is isotonic, however, if the tension in the muscle remains constant during the contraction.

Plants get their energy from the sun using Photosynthesis and animals get it from eating food.
The definition is the study of life
Answer:
I think the answer is
D. The planet is extremely hot.
Explanation:
It's because there is no water left on the surface, which helps cooling down the planet and the atmosphere contains thick and excessive carbon dioxide which traps the heat, causing the planet to heat up.
