Why do most earthquakes take place at tectonic plate boundaries?
a. the rock in the interior of a tectonic plate is stronger, so it does not deform.
b. earthquakes take place where the motion of tectonic plates transfers energy to rock.
c. earthquakes can only occur at places where magma can reach the surface and transfer energy to rocks.
d. earthquakes take place when one plate moves over another plate, which happens only at plate boundaries.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

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.
