Which group of non-prokaryotic organisms studied in microbiology typically have two life cycle stages: trophozoite and cyst?
Mama L [17]

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.

<h3>What is Protozoa?</h3>
  • Protozoa is a group of single celled, non- prokaryotic organisms.
  • These may either be free living or parasitic in nature.
  • These are heterotrophs and reproduce asexually by binary fission.
  • The Protozoa consists of many unrelated or loosely related organisms.
  • They are divided into four major groups:  Sarcodina, Flagellates, Ciliates and Sporozoans..
  • Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
  • Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
  • The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

Contact [7]
The correct answer is stabilizing selection reduces the amount of variation in a trait. disruptive selection increases the amount of variation in a trait.

Stabilizing selection is a type of natural selection in which genetic diversity decreases because natural selection favours an average phenotype and selects against extreme variations.
<span>
Disruptive selection is a type of natural selection in which extreme values for a trait are favoured over intermediate values, thus it increases genetic variance.</span>
