Answer:
C. I and III
Explanation:
A mutation needs to occur in a gamete cell in order to be passed down to the next generation.
If it occurs in a somatic (body) cell, the mutation will only be present in that organism.
On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.
So, since sperm and egg cells are gametes, mutations in those cells would get passed on.
The correct answer is C. I and III

:
D. Both competition and environmental filtering shape community structure.
Explanation:
Based on competition theory, two organisms occupying the same ecological niche can only coexist provided there is spatial or conditioning niche partitioning.This prevent competitive exclusion , ensuring survival of the two species in their niche. Since the two species developed greater variability in (over-dispersed traits) to resist the selection pressure,(competition).Many overdisperesed traits is present in the communities.
However environmental filtering, is concerned with selection of species with natural ability or triats to survive in a given communities,Thus if two species of organism meet the same ecologocal requirements in a community, environmental filtering, fitters them and ensure their survival ahead of others who do not meet the requirements, and could not survive.
Thus the simultaneous operation of theses two opposing selection pressures, structured communities ensuring coexistence and favoured ability of organism to survive.
Answer:
Yes.
Explanation:
Recent developments in biology have made it possible to acquire more and more precise information concerning our genetic makeup. Although we have only begun to see the most far-reaching effects of these developments and the completion of the Human Genome Project, scientists can even today identify a number of genetic disorders that may cause illness and disease in their carriers. The improved knowledge regarding the human genome will, it is predicted, soon make diagnoses more accurate, treatments more effective, and thereby considerably reduce and prevent unnecessary suffering. The knowledge can also be, however, depending on the case, futile, distressing, or plainly harmful. We propose to answer in this article the dual question: who should know about our genetic makeup and why? Through an analysis of prudential, moral, and legal grounds for acquiring the information, we conclude that, at least on the levels of law and social policy, practically nobody is either duty-bound to receive or entitled to have that knowledge.
