comment When writing about past research should I use the species name they employed or the modern version?
+1 Also note that it is common that older synonyms are given (sometimes many), e.g. in a parenthesis in the introduction or in methods (where the organism is described). In species determination literture or taxonomic papers clarification of synonyms are often done under a specific heading.

This is not a question, but a restatetment of an assignment.

comment Which (naturally selected) evolutionary process led to the development of egg-laying?
From an evolutionary standpoint (which was the original question), this answer is meaningless. Mammals evolved from egg-laying ancestors, so you cannot argue that egg-laying evolved because it is e.g. more energy efficient than in mammals/viviparious species (there is also internal development in some egg laying species, see Ovoviviparity).

@HDE226868 Don't be sorry. Multiple answers are encouraged, and improves the quality of the site.

comment What impacts penetrance of Huntington's disease?
To me, it seems like you are arguing against the "exclusively environmental" idea in the section on Huntingtons. What makes you think/ask that it is exclusively environmental? The short answer to the title Q is No - the genetic background (genes at other loci) can for instance affect penetrance. You should also include a reference to the book you've scanned.

This looks like homework. See the homework policy of BioSE.

comment The gender of offspring of Twins?
While I agree with you in a practical sense, your answer is assuming that the sex ratio is 50/50 for all couples/populations and that variation in sex ratio lacks a heritable component, which is an open empirical question. Heritable variation in sex ratio is known in many non-human animals.

comment Are Humans Evolving?
I agree with @MattDMo. Reproductive isolation can speed up evolution and facilitate local adaptation, but it is not at all necessary for evolution. Your question seems to focus on speciation, not evolution in general.

comment Are Humans Evolving?
This Q has a slightly different angle, but is still very close to being duplicate of How is evolution possible in contemporary humans? and Human Evolution in Modern Times. Also related is Are there any scientifically based predictions or theories of future human evolution?.
