Which of the following is a function of the kidneys? O A. To balance water and salts from food so cells neither shrink nor
burst
O B. To balance carbon dioxide and oxygen so cellular respiration can
occur
O C. To filter out fiber and bacteria and send them to the large intestine
O D. To filter out salts and fats and send them to the urinary bladder

D. To filter out salts and fats and send them to the urinary bladder

Explanation:

Kidney is an excretory organ in the systems of certain living organisms e.g humans. It is a bean-shaped organ responsible for getting rid of waste products in our body via urine and maintaining homeostasis in the body.

Among the many excretory functions of the kidney, they help filter out electrolytes e.g salts and fats out of the blood and pass them to the urinary bladder through tubes called ureter. The waste products are eventually passed out as urine from the bladder.

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

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.
