In 1990, scientists at the national institutes of health used gene therapy to try to treat a 4-year-old girl suffering from severe combined immunodeficiency disease (scid). this genetic disease made her extremely susceptible to infections. the scientists used a virus to inject normal genes into the girl's immune system cells. the experiment was moderately successful, and the girl's health improved but only for short periods of time. if this form of gene therapy could be fine-tuned, how would it impact society? a. people would need to be genetically tested before having children together. b. many genetic diseases would be curable. c. the number of infections from genetically-engineered viruses would increase. d. most americans would no longer suffer from heart disease.

B. Many genetic diseases would be curable.

Explanation:

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

archaebacteria are found in in forest soil.

hope i spelled it right lol

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
