D. Darwin's theory of natural selection shows that organisms evolve based on which one's survive the best and thrive.
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:
Photoperiodism is a plant's response to the number of hours of darkness in its environment. b. Plants that flower when exposed to less than 10–12 hours of darkness are called long-day plants.
Explanation:
Weathering can be caused by rain,snow,heat,and as well as wind.
Pros: Might someday cure disease, might someday increase crop yeild, might create things that can be of our use.
Cons: Genetic engineering could cause food allergies, have bad side affects, it could kill animals over time.
I hope this helps.
