What are the four major points of Darwin's theory of natural selection?

1. Overproduction - more offspring are born than survive

2. Genetic Variation - there is variation in the population

3. Struggle to Survive - organisms with suitable variations will survive and reproduce

4. Differential Reproduction - suitable variations are passed on to offspring

The open ocean begins at the low-tide mark and extends to the end of the continental shelf

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

The answer is centrioles forming happens in animal cell mitosis but doesn't happen in plant cell mitosis.
