Shivering is . Multiple Choice the rapid, voluntary contraction of smooth muscles the rapid, voluntary contraction of skeletal muscles the rapid, involuntary contraction of smooth muscles the rapid, involuntary contraction of skeletal muscles

The correct answer is - involuntary contraction of the skeletal muscles.

Explanation:

Shivering or the chills that is involuntary action of body to maintain the homeostasis by controlling the body heat or maintaining body temperature it can cause by environmental change or the infection.

It is rapid involuntary contraction and relaxation of the skeletal muscles whenever body needs to produce heat when ti feels cold. Skeletal muscles are act as thermal effector in such cases.

Thus, the correct answer is - involuntary contraction of the skeletal muscles.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
