1. Polymerization (the formation of polymers) is a process that
a. creates bonds between R groups in the forma-
tion of a polypeptide.
b. involves the removal of a water molecule in a
dehydration reactions to
c. links the nitrogenous base of one nucleotide
with the phosphate of the next.
d. may involve all of the above.

when it is at an intermediate population density

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.

c is the answer. hope this
