Filtrate is formed as fluid is forced through the walls of the glomerulus and
Goryan [66]

Answer:

initially, collects in the structure indicated by the letter B

Explanation:

Filtrate is formed as fluid is forced through the walls of the glomerulus and, initially, collects in the structure indicated by the letter B.

Urine formed by a kidney collects in the renal pelvis before being drained from the kidney by the urethra and transported to the urinary bladder.

The process by which glomerulus filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.

What is the basic difference in effector function between helper and cytotoxic T cells?
3241004551 [841]

Answer:

Helper T cells stimulate B-cells to produce antibodies and killer T cells to destroy the non-self cells. Cytotoxic T cells on the other hand are direct attack cells. They can kill the micro organisms by creating pores on the invader's cell.

Explanation:

T lymphocyte mediated immunity of cell mediated immunity do not secrete antibodies but they help stimulate the B cells to produce them. Immature T cells are produced in bone marrow from where they migrate to thymus via blood. In the thymus maturation of T cells occur and then they migrate to lymphoid tissue and get differentiated into three types:

a. Helper T cells: As the name suggests, they help in activating other immune cells, in other terms they are the regulator of virtually all functions of immune system. Protein mediator called lymphokines are produced by these helper T cells in order to regulate the immune functions. Some examples of these lymphokines are: Interleukin-2 interleukin-3, interferon gamma. T helper cells stimulate the B-cells to produce antibodies.

b. Cytotoxic cells or killer T cells: The lymphokine interleukin-2 is responsible for the growth and proliferation of both cytotoxic T cells and suppressor T cells. With the help of receptor proteins on the surface of killer T cells, they bind to the specific antigen. After binding, they secrete a pore forming protein called perforins which create pores on the invaders cell membrane for water to enter into it thereby cell swells and finally lyse.

c. Suppressor T cells: They suppress the function of above two T cells.

Give ONE suggestion for how humans can lessen their impact on Earth.
lora16 [44]

Answer:

Humans must decrease the harmful impact they have on earth or else the human population could go extinct forever. One way to do this is to inform the people on climate change and its effects. Recycling, using metal straws, carpooling, cleaning up beaches, pulling unncessary plugs in your house to reduce electricity usage, and doing so much more can help reduce the risk of climate change and help the world become a much healthier and stable place for humans, plants, animals, and the environment.
