What cardiovascular process are you modeling when you squeeze the plastic
bottle?

Squeezing a plastic bottle mimics the cardiac systole of the cardiovascular cycle.

Explanation:

Cardiovascular System:

Composed of the heart and circulatory system, the cardiovascular system transports nutrients and oxygen to the body. The heart functions as a pump, following the cardiac cycle to transport blood.

Cardiac Cycle:

A cardiac cycle defines the contraction and relaxation of the heart chambers. It comprises of:

The diastole is defined as the relaxation of heart muscles when its chambers are being filled with blood. Atrial diastole indicates the filling of the right and left atria.

The systole is the contraction or "squeezing" of the heart muscles that squeeze the blood outside of the heart. Atrial systole pushes blood out of the heart to the lungs. Ventricular systole pushes blood to the aorta that supplies blood to all parts of the body.

Therefore, as squeezing a plastic bottle pushes liquid out, it resembles a cardiac systole.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:

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.
