All except which of the following are characteristics of the genetic material?

a. it must be replicated accurately.
b. it is composed of protein.
c. it must be capable of change.
d. it contains all the information needed for growth, development, and reproduction of the organism.

B: it is composed of proteins.

Explanation:

All the options above are true for a genetic material except that its composition is not made up of proteins but of four chemical bases also known as nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T) attached to a sugar (ribose) and a phosphate molecule: hence the name deoxyribonucleic acid.

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.
