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.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
