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.
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.

Answer:
d. symbiosis
Explanation:
Biotechnology is a field of science in which we study about the beneficial microorganisms and use it for the production of industrial products. In biotechnology, scientists made medicine from microorganisms due to the insertion of specific gene in the bacteria. After sometime, bacteria accept that gene and started the production of that gene. This method is used for the production of insulin.
