Imagine that a disorder that causes the cell cycle to stop affects the muscle cells of a frog’s leg. what consequence is most likely to follow? a. the frog will not be able to hop using that muscle. b. an injury to the muscle will not heal. c. the frog will not be able to reproduce. d. a broken bone in that leg will not mend.

b. an injury to the muscle will not heal.

Explanation:

Cell cycle refers to the orderly events that form new cells from the existing ones. The newly produced cells help in growth and development as well as serve in healing by replacing the damaged cells.  

Since the frog has a disorder that does not allow its leg muscles to carry out the cell division, any injury to the leg muscle would not heal. The lack of the process of cell division would not allow the formation of new cells. And without new cells, the injured muscles cannot heal.  

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
