Using a dark line for the original parental DNADNA and a wavy line for DNADNA synthesized from parental DNADNA, show what the population of DNADNA molecules would look like in the fourth generation. (Parental DNADNA is the first generation.)

the answer is true. hope it .

the answer is 0.8m.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
