How many hg/dam" in 3.5 g/cm3?

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

16- counting by fours

Yeah give more information 

a) adding base pairs

c) unwinding the helix

 

there are possible two correct answers for this question.

dna polymerase doesn’t add base pairs, it adds single nucleotides which are complentar to coding strand . also dna polymerase can’t unwind the dna helix alone. dna helicase can do that, using energy derived from atp hydrolysis.

dna polymerase are enzymes that synthesize dna molecules from deoxyribonucleotides. these enzymes replicate the dna strand and create two identical dna strands from a single original dna molecule. some of dna polymerases have a function of correcting erros which are made during replication and this process is called proofreading. if the dna polymerase detects that incorrectly paired nucleotide has been added, it will remove and replace the wrong nucleotide.
