When only skeletal remains are available for identification, the gender of the deceased individual can be determined by:?
zlopas [31]
The answer would be skeletal markers and DNA analysis. 

Skeletal markers are often used to identify the biological gender of skeletal remains. The most commonly used skeletal markers can be observed in the skull and in the pelvic bone.However, the accuracy of his method is limited to adults only the differences between male and female skeletal markers usually become visibly only after maturation. 

DNA analysis is more widely uses nowadays because with the technology of today, laboratories can now detect and X and Y chromosome-specific sequences, which help them identify the biological gender.

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.
