Answer:
Animals are born knowing how to do something instinctual, but they must be taught learned behaviors and practice them to get good at them. Male birds of paradise are known for having bright markings that they flash while making complex movements when females are nearby. ... This is an example of courtship behavior.
Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
One example would be that the sleep schedule of animals might be thrown off. It would be dark the whole day, so the crepuscular (dawn/dusk) animals might be a bit confused, as would the nocturnal (night) animals. Would they stay awake all "day" and all night? What about the diurnal (day) animals? Would they just not come out all day long?
