We will also be telling you how cancer affects the digestive system and its ability to maintain homeostasis. Body temperature is an example of what affects homeostasis. ... First of all, the digestive system helps you transfer food to your stomach and it takes the good stuff and transfers it using the circulatory system.
<h2>Answer:</h2><h3 /><h3>Alternative splicing is a process that occurs during gene expression and allows for the production of multiple proteins (protein isoforms) from a single gene coding. ... For example, if a pre-mRNA has four exons (A, B, C, and D), these can be spliced and translated in a number of different combinations.</h3>
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.
Answer:
Mineral C
Explanation:
Mineral C can scratch apalite, due to its higher hardness, but can be scratched BY feldspar due to it being slightly lower than feldspar.
If all nations agreed to reduce global warming then It would be good because the seals need icy conditions. So the less global warming then the more icy habitats there will be and the seals will have more places to live.
Hope this helps
