  • Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

The correct answer would be D. beaks of finches

I chose this answer because in the Galapagos islands, the species of finches were forced to separate into several different environments, where there were different foods and plants. They lived in these environments for many years and eventually the beaks of these birds adapted to the environment around them. So the finches in one environment may have gotten longer beaks to eat fruits and get honey better, while one may have gotten a smaller but longer beak to gather and break nuts easier.

Hope this helps!

Elza [17]

Answer:

Answer of the question is explaine dbelow.

Explanation:

Rho GTPases interact with a variety of effectors to control actin cytoskeleton

reorganization, cell shape, and cell polarity. RhoA regulates cell shape and adhesion by

the assembly of contractile actin microfilaments into stress fibres. Rho GTPases also

regulate proliferation and cell-cycle progression, especially GuS transition.

All the cells are about to enter mitosis means they cross GuS transition, a drug that is a

potent inhibitor of RhoA activity has no affect on the cell because these cells already in

G2 phase. So, all the cells appear to be in telophase.

So, the correct choice is A. all the cells appear to be in telophase.
