Explanation:
Between prokaryotes and eukaryotes, which type of cells are believed to have evolved first? Scientists have concluded that prokaryote life forms preceded the more complex eukaryotes. All organisms on Earth are classified into two basic cell types. Kary means nucleus.
The correct answer is b, antigens
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.

Incomplete dominance can happen in flowers such as snap dragons where a red flower plant and a white flower plant have an offspring that is neither red nor white but is a mix so in this case it would be pink. It does not support the blending theory as it does not get its colour from the dominant plant in this case but from both.
