Ribsosomes
Why does interphase occur?
Normal cell activities, DNA replication, and cell growth.
What is a fossil record?
The principle of fossil succession and the theory of evolution helped geologists to interpret fossil records.
How does convergent evolution support the theory of evolution?
It shows that different organisms had to evolve or change to adapt to their changing environment.
