7. Elements in columns (groups) 3-12 are called theMetals, whose outermost electrons are found in the d sublevel. Color these elements a different color and reference this group on the legend.

mol/g

explanation:

i had a similar question and i got it right so i think this one is right.

the complete reaction for the formation of aluminum oxide is as follows;

4al + 3 > 2

so if the molar mass of the is 32.0 g/mol and

so, to form 3.80 mol of

(3.80 mol ) x (3 mol ) x (32.0 g )

dividing by 2 because two moles of will be formed;

∴ 364.8/2   = 182.4g

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.
