Explanation:
In evolutionary theory, the relationship between the rough-skinned newt and the common garter snake is considered an example of co-evolution. The mutations in the snake's genes that conferred resistance to the toxin have resulted in a selective pressure that favors newts which produce more potent levels of toxin.
b. Angiosperm
Explanation:
Acorn is the fruit of oak tree. It is a nut and bears only one seed.
Since the scientist finds that the fruit produced on the tree is a nut then it is obviously an angiosperm because:
The only groups of seeded plant are Gymnosperms and Angiosperms.
Gymnosperms produce cones and have naked seed.
The seed produced within a fruit is a characteristic of angiosperm.
