As DNA polymerase adds new nucleotides it's creating a new nucleic acid polymer. What kind of reaction is this enyme facilitating? A. hydrolysis

B. dehydration

C. catalysis

D. exothermic

C. Catalysis

Explanation:

The polymerase catalyzes the nucleophilic attack of the 3′ hydroxyl group terminus of the polynucleotide chain on the α-phosphate group of the nucleoside triphosphate to be added

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
