Answer:
Transcellular.
Explanation:
The transportation of solutes and water occurs in the proximal convoluted tubule. The transport of solute occurs mainly via the two routes of transport known as paracellular transport and transcellular transport.
Transcellular transport may be defined as the transport by the cell through the cell. This process requires the energy for the transportation of molecules across the cells. The solutes are transported through the cell and most common route of transfer present in the proximal convoluted tubule.
Thus, the correct answer is option (a).
Answer:
Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.
Explanation:
Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.
Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.
Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.
Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
Answer and Explanation:
Sperm cells are stored and produced in the Testes of a male. The testes are linked to the rest of the male reproductive organs by the vas deferens, which extends over the base of the pelvic bone or ilium, and wraps around to the ampulla, seminal vesicle, and prostate. The urethra then runs from the bladder through the penis.
