Proximal convoluted tubule
Loop of Henley
None of the above
Proximal convoluted tubule is the part labeled from the above diagram of nephron.
What is nephron?The nephron is the small microscopic structural and functional unit of the kidney. It comprises of a renal corpuscle and a renal tubule. The renal corpuscle is composed of a tuft of capillaries which is refer to as the glomerulus and Bowman's capsule. The renal tubule extends from the capsule.
Therefore, The proximal convoluted tubule is a portion of kidney nephron between the loop of Henle and the collecting tubule.

What is the difference between B-cell lymphocytes and T-cell lymphocytes?
B cells regulate blood pH, and T cells regulate body temperature.
B cells are produced in the thymus, and T cells are produced in the bone marrow.
B cells engulf bacteria, and T cells carry bacteria to the lymph nodes.
B cells produce antibodies, and T cells destroy infected cells.
Answer:
B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism. Both the cells are made in the bone marrow.Explanation:
B cells produce antibodies, and T cells destroy infected cells. So, the correct option is D.
What are B cells and T cells?The two primary categories of lymphocytes are T cells and B cells. Antibody molecules made by B cells can attach to and kill invasive viruses and bacteria. T cells are the immune system's first line of defence against foreign invaders. They also create cytokines, that are biological agents that aid in the activation of other immune system components.
T cells can eliminate malignant or contaminated cells. Moreover, they control overall immune response by assisting B cells in eradicating foreign infections. Antibodies are made by B cells. An antibody is a class of protein produced by B lymphocytes, sometimes known as B cells.
Therefore, the correct option is D.

On the Galápagos Islands, Charles Darwin observed Question 1 options: completely unrelated species on each of the islands. species exactly like those found in South America. species similar to mainland South American species. species completely unrelated to those found in South America.
We can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.
What did Darwin notice about these species?Darwin noticed that each of these species were very similar, but possessed slightly different traits. These traits seem to perfectly fit the needs of each species for their specific island, leading to his creating the theory of evolution through natural selection.
Therefore, we can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

Analyze the graph and identify some factors that may contribute to the rotifer population leveling off in the absence of water fleas. Explain your answer in 1–2 sentences.
Answer:
(Leveling off = it stays the same even though it had a increasing period) When looking at the end of the graph you can see that it came back to what it was, which means the rotifers are not increasing anymore. That's because of the carrying capacity (a species' average population size in a particular habitat), and the carrying capacity in this situation is the flask. Therefore the flask has limited space.
