Answer: Genetic engineering is a tool in biotechnology wgich is beneficial to both the organism, the society and the environment.

What is genetic engineering?

Genetic engineering is a technique in biotechnology in which genes of organisms are manipulated to produce desirable effects in the organism.

Genetic engineering provided benefit to both the organism as well as the society.

To the organism, it gives the organism an advantage of increased chances for survival, for example producing disease-resistant crops.

To the society, it enhances food production as plants produce more food when healthy.

To the environment, it enables these disease to disappear as they can no longer affect organisms.

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.

Fructose is? also known as dextrose. the sweetest of the sugars. abundant in whole grains. a starch. known as milk sugar.
Elina [12.6K]

Dextrose and fructose are both types of sugar. the sugar with the best flavor. plenty of whole grains. the starch. called milk sugar.

It is also found naturally in other plant foods such as honey, sugar beets, sugar cane, and vegetables.  Fructose is the  sweetest naturally occurring carbohydrate, 1.2 to 1.8 times more  sweeter than sucrose (table sugar). is the sweetness of Fructose metabolism does not require insulin and has little effect on blood sugar levels.  There are many different types of sugar, some  more common than others. Fructose, like glucose, is a type of sugar known as a simple sugar or "simple sugar". Monosaccharides can be combined to form disaccharides, the most common of which is sucrose, or "sugar." Sucrose is made up of 50% fructose and 50% glucose. Fructose and glucose have the same chemical formula (C6H12O6), but due to their different molecular structures,  fructose is 1.2 to 1.8 times sweeter than sucrose. In fact, fructose is the sweetest natural carbohydrate.

In nature, fructose is most commonly found as a component of sucrose. Fructose is also found in plants as a simple sugar, but that doesn't mean other sugars don't exist.
