Answer:
Explanation:
Since Mark's wife was a carrier, it means that she is heterozygous for the trait. And after Mark got tested, they decided to have children due to no increased risk if they do have children, it means the condition is not an autosomal dominant condition but a recessive condition because if the condition is dominant, only one copy of the affected allele is needed to increase risk.
Thus, with a no increased risk, it means Mark is normal i.e. carries no copy of the recessive allele.
Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.

Answer:
The correct answer is B. prokaryotes
Explanation:
Archaea and bacteria are the organisms that come under prokaryotes. In Prokaryotes, pro indicate before and karyote indicate nucleus. So these organisms do not have a true membrane-bound nucleus in which they can store their genetic material.
As archaea and bacteria do not have membrane-bound nucleus their genetic material freely moves inside the cytoplasm in their cell. All the prokaryotes are unicellular organisms.
The organisms that have a well membrane-bound organelle like nucleus are called eukaryotes. The genetic material of these organisms are packed in their nucleus. They can be unicellular or multicellular.
Therefore the correct answer is B. prokaryotes.
