Two adaptations of a saguaro cactus in order to store water are as following:
1. large stems can store water.
2.thick waxy skin in order to reduce water loss through pores.
In a ring species gene flow occurs between neighboring populations of a species, but at the end of the ring populations don’t interbreed.
Answer:
A, Both cells will replicate their DNA.
Explanation:
During the cell division, cell passes through several phases and divides. Before each phase, the cell has to pass through the checkpoints. At these cell checkpoints, the cell receives the internal and external signals.
When the cell is arrested at G₀ phase, the cell does not divide until it receives a signal to proliferate but when the cell passes the G₁ phase, the cell will divide continuously.
In the given question, if the cells when in their G₀ and G₁ phase receive proliferation signal, the G₀ phase cell will also divide and will replicate it DNA during S phase as G₁ phase cell will do.
Thus, Both the cells will divide their genetic material.
