Which of the following is the best definition of DNA

A.

Explanation:

Choice B is incorrect. That definition can be applied to both DNA and RNA, as they are both made of a nucleic acid, phosphate, sugar ring, and nucleotide base.

Choice C is incorrect. That would be the message strand made by RNA when they are transcribed.

Choice D is incorrect because it's absurd.

currents is the correct answer.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
