Which part of the nephron is involved in filtration? proximal convoluted tubule peritubular capillary loop of Henle glomerular capsule.

Answers

Answer:

The correct answer is glomerular capsule.

Explanation:

The glomerular capsule or the Bowman's capsule refers to a cup-like sack at the initiation of the tubular part of a nephron in the kidney of a mammal, which performs the initial step in the filtration of blood to produce urine. In Bowman's capsule, the blood filtration process is termed as glomerular filtration or ultrafiltration.

The usual rate of filtration is 125 millimeters per minute. Any small molecules like glucose, water, amino acids, salts, and urea can pass into the Bowman's space without any hindrance, however, the platelets, cells, and large proteins do not passes through.

Final answer:

The glomerular capsule, or Bowman's capsule, of the nephron in the kidney is responsible for the process of filtration, separating smaller molecules from larger ones.

Explanation:

The part of the nephron involved in filtration is the glomerular capsule, also known as Bowman's capsule. The process of filtration occurs here, where blood under high pressure flows into the glomerulus from the afferent arteriole and the filtered kidney filtrate moves into the tubule system of the nephron. This process separates smaller molecules like water, glucose, and salts from larger molecules such as proteins and cells, preventing them from being lost in urine.

Tundras have a high diversity of species.

Answers

Let's look at all the statements:Which of the following statements is true? Parts of an ecosystem only include biotic factors such as plants and animals. - this is not true, it also includes abiotic factors, such as stones If a common plant in an ecosystem becomes diseased, the ecosystem may become unbalanced. - this is the true statement! it could be a source of food for other animals, and thus it could influence the population of other species Abiotic factors include decomposers such as fungi and bacteria. - this is false, those are biotic factors. Tundras have a high diversity of species. - this is not true - compared to the rain forest, for example, tundras are not very diverse

Answer: if a common plant is in an ecosystem becomes diseased the ecosystem may become unbalanced.
