Answer:
The sample treated with RNase
Explanation:
According to this question, a novel virus was found which was capable of killing mice when injected into them and capable of making a nonvirulent virus to be virulent by transforming them.
After heat killing the novel virus, different samples were treated with either an RNase, a DNase, or a Proteinase. If the novel virus uses double-stranded RNA as its genetic material, the sample treated with RNase will no longer be capable of transforming the non-virulent strain. This is because RNase is a catalytic enzyme that degrades RNA, hence, the RNA will no longer be present to transform.
The answer is B Microscope :)
The pulmonary embolism is mostly likely to have originated from the Deep veins of the leg response feedback. Pulmonary embolism occurs when a clump of material, most often a blood clot, gets wedged into artery in your lungs. These blood clots most commonly come from the deep veins of your legs. It is a blockage of an artery in the lungs by a substance that has moved from else where in the body through the bloodstream.
It’s increasing its chances of survival.
