If 5% of a DNA sample contains adenine, what percentage is Thymine? How about Guanine? Cytosine?

Lol! I had this for homework for biology class too.  Thymine should be 5%, and Guanine and Cytosine should both be 45% I think.

Explanation:

Since A is 5% and T pairs with A, T should also be 5%. These two combined is 10%.

100-10 = 90

We still have two left, Guanine and Cytosine, so 90/2 = 45

That should mean G and C are both 45%.

preservation because he preserves part of the land and preserves means save

explanation:

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.
