Answer: The correct answer is option a.
Explanation:
Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.
It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.
Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.
Hence, it is a type of prezygotic isolation.

Answer:
Do the organism's colls have nuclei?
Explanation:
Protists represent eukaryotic organisms whose cells contain a nucleus and organelles delimited by membranes, whereas Archaea and Bacteria are unicellular prokaryotic organisms that lack a cell nucleus, in which the genetic material (chromosome) is localized in a part of the cytoplasm named nucleoid. Eukaryotic organisms include protists, animals, plants, fungi, and most algae. Most protists are unicellular, although there are species that are multicellular.

''Watching television adversely impacted the quality of sleep''.
Explanation:
''Watching television adversely impacted the quality of sleep'' is the best hypothesis for her study. Watching television right before bed, can negatively impact your sleep quality.
