<u>Answer:</u>
Temperatures it experiences could be included in the description of a grasshopper’s niche, but not in a description of its habitat.
<u>Explanation:</u>
- The habitat is the organism's place where it lives and niche is physical and biological condition of spices that exist.
- Grasshopper is a herbivorous insect that can "leap 20 times" of its "own body" and it jump almost 40 yards.
- Female grasshopper is larger than the male and it can be found almost every where in the world except the coldest region.

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.
