Answer:
The correct answer is "It prevents spontaneous muscle's contraction".
Explanation:
Muscle contraction is produce by the interaction of actin and myosin filaments. Basically, myosin binds to the active sites of actin, which produces a protein complex (known as actomyosin) that allows that the filaments slide past each other and generate a contraction. When troponin and tropomyosin block the active sites of actin prevents spontaneous muscle's contraction, because a nervous impulse is needed to remove the inhibitors and that myosin starts the contraction.
Answer: The principle of dominance states that some alleles are dominant and others are recessive. An organism with a dominant allele for a particular form of a trait will always exhibit that form of the trait. An organism with a recessive allele for a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
Explanation:

Recessive= t Tt tt

Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
<span>The correct answer is A, B and D. Biogeochemical cycles are central to the ecology of earth system. They make the essentail elements accessible and available for the organisms, and maintain their levels, so that the ecology is ot disrupted. The elements move through abiotic and biotic factors, in these cycles, and a state of equilibrium is maintained n the ecosystem. The carbon dioxide levels are responsible fr the temperature of the earth. If Carbon cycles would not have existed, then there would have been a disruption in maintaining the global temperature. Biogeochemical cycles basically continuously recycles the essential materials, for sustaining the life-forms.</span>
