Create a series of yes/no questions that will help someone looking only at the DNA to determine if a cell is eukaryotic or prokaryotic. Your key must have three questions and must come to a definite conclusion (specifically, "the cell is eukaryotic" and "the cell is prokaryotic"). Drag each question to its correct location.

Answer and Explanation:

1- Is the DNA surrounded and protected by a membrane?

a- yes4

b- no2

2- Is the DNI in contact with the cytoplasm?

c- yes3

d- no4

3- Is the DNA a unique circular rolled chromosome?

e- yes6

f- no4

4- Is the DNA chain fragmented into many chromosomes?

g- yes5

h- no6

5- Is the DNA associated with histone proteins forming the chromatin?

i- yes> "the cell is eukaryotic"

j- no> 6

6- Is the DNA associated with non-histone proteins forming a nucleoid?

k- yes> "the cell is prokaryotic"

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.
