Answer:
d. Humans and other animal hosts lack peptidoglycan cell walls.
Explanation:
Humans and other animals lack cell walls. Bacterial cells have peptidoglycan cell walls around them. The absence of cell walls in the cells of human and other animal host ensures that these cells are not affected by the drugs that target the peptidoglycan cell walls to kill or slow down the growth of the bacterial pathogen.
This makes the drugs specifically target the bacterial cells only while not affecting the host cells. If a drug would target a component present in cells of both the pathogens and hosts, the host cells would be most likely to be harmed by the drugs.
Answer:
Cellulose-digesting microorganisms live in the guts of termites and ruminant mammals. the microorganisms have a home and food, and their hosts gain more nutrition from their meals. this relationship is an example of mutualism.
Explanation:
Mutualism encompasses the ecological relationships between individuals of different species, in which both gets benefits and improve their biological functions. It usually occurs between species that have different nutritional and living requirements.
An example of this is also the nitrogen fixing bacteria (Rhizobia) and the legimunous plants, and the relationship between the Acacia and the Acacia ants.

Explanation:
Haplotype research served to discover the origin of genetic mutations that today manifest as pathologies.
It is very important to know that there are no equal haplotypes in two or more different humans.
They are the allelic constitution of multiple loci for the same chromosome.
Furthermore, haplotypes are very good for studying population genetics.
I leave you a table that will help you for this exercise or many more, where the haplotype system is outlined.
