Is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra. a) blood b) plasma c) sweat d) urine

Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra.

Option D

Explanation:

In our body, presence of urinary tract filters extra fluid and other substance from the blood. The substances get excreted from our body in the urine type.

Urine, a liquid generated by the kidneys, accumulates in bladder, and then excreted from the urethra. Urine used to remove excess minerals and to remove blood cells from body. The urinary tract consists of the kidneys, urethra, bladder and ureter.

The urinary systems function in conjunction with other systems of the body to handle homeostasis. The kidneys play as the important organs of homeostasis. They balance acid-base and water-salt in the blood.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
