Answer 2

❶ Tadpole develops into an adult frog by the process of ${\underline{\textsf{\textbf{\pink{metamorphosis}}}}}$.

REMEMBER POINTS :

1. As the metamorphosis is the change that occurs in the organisms, it's a kind of physical change that transforms an immature form of an organism to a matured form also called adult.
2. So, here a tadpole is developing into a adult frog.

❷ The number of nuclei present in a zygote is ${\underline{\textsf{\textbf{\pink{one}}}}}$.

REMEMBER POINTS :

1. Zygote is diploid (2n).
2. A zygote is a cell formed when two gamete cells are fused by means of sexual reproduction.
3. Here, the sperm nucleus fuses with the egg nucleus to form a single zygote nucleus.
