Answer:
Eukaryotic genetic variation occurs with VERTICAL gene transfer while prokaryotic genetic variation occurs with HORIZONTAL gene transfer
Explanation:
In Eukaryotes, genes lays on top of each since they reproduce sexually this gives rise to their genetic variation and hence the vertical gene transfer, but prokaryotes lie side by side, reproducing by conjugation, transformation and transduction. This makes their genetic variation to be horizontal.
Example is conjugation in Spirogyra.

.
C. The intensity of emotional responses is more accurately measured after the event in laboratory studies
.
D. Memories and emotional experiences as in real life are very different from those generated in laboratory studies.
The correct answer is option D.
Explanation:
Generalizability measures how useful is what scientists have been studying in a laboratory in comparison with the real-life since the first option is a prototype of reality that can miss valuable variables that can have an impact on the real life. With generalizability, we can see if the results of the investigation and the process that scientists used are useful in real life and can apply to other things or communities. The efficiency of generalizability depends on how well the representation of reality was in the laboratory.
