If a boy exhibits a sex-linked trait that is carried on the X chromosomes, his mother carried at-least one allele for that trait. 
The boy has a X chromosome inherited from his mother and he inherited Y chromosome from his father. So, his mother must carried at least one allele for that trait because he exhibits a sex linked trait that is carried on X chromosome.

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.
