Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA.

C) both an aggregate fruit and an accessory fruit
Explanation:
When several flower ovaries or receptacle of a flower with many separate carpels joins together they form aggregate fruit. Each ovary has a single ovule that converts into a seed after fertilization.

Strawberry is also an accessory aggregate fruit because the different ovaries in the strawberry develops into achenes over the surface of flower receptacles.
