Bacteria can cause many diseases, including diptheria, meningitis, and pertussis. However, there are also beneficial bacteria that

help with digestive processes, the decomposition of dead matter, and the fermentation of yogurt and cheese.

Viruses can also cause diseases, including influenza, HIV, and varicella. Although viruses are not generally considered beneficial

what is one positive use for viruses?

OA.

Viruses help organisms manufacture vitamins and fatty acids.

OB.

Viruses have a low rate of mutation, so they are easier to cure.

OC.

Viruses can be used to insert genetic material into cells during gene therapy.

OD.

Viruses can be used as non-toxic decomposers to break down dead matter.

Viruses can be used to insert genetic material into cells during gene therapy

Explanation:

Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
