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. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
