Some steps in cell division are shown below:

1. chromosomes condense and pair up
2. segments of dna of sister chromatids twist and cross
3. exchange of dna occurs between chromosomes
4. four daughter cells are created that are haploid

which of the following steps is least likely to occur during meiosis 1?

step 1
step 2
step 3
step 4

Step 4

Explanation:

Bcoz only 2 haploid cells are formed at the end of meiosis 1st...at the end of meiosis 2nd.. 4 haploid cells formed

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 .. .
