Which of the following statements is true?

Egg cells have 46 chromosomes.
Genes exist in specific locations on a chromosome.
There are more chromosomes than genes in the human body.
There are more genes than DNA base pairs in the human body.

i think its the 2nd one

Explanation:

the rest are wrong

I think the answer is Egg cells have 46 chromosomes, because Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.

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.

hope this .. .
