It is true that uni-potent stem cells can only produce cells that are like themselves
Answer: Option B
<u>Explanation:</u>
Uni potent cell as their name suggests can only produce cells that are just like themselves. Compared to the other stem cells that undergo proliferation this produces a tissue of that particular type alone.
Though it can’t be of much use like other cells giving rise to different cell types this is confined to the generation of one particular tissue. The uni-potent cells help to renovate and recreate themselves too. Hence any damaged tissue can be replaced by the uni-potent cell giving rise to the same tissue in case of burns etc.
Answer;
-Archaeocytes
Cells that move about in the mesohyl, digest particles, and may specialize for other functions are the archaeocytes.
Explanation;
-Archaeocytes are very important to the functioning of a sponge. These cells are totipotent, which means that they can change into all of the other types of sponge cells.
-Archaeocytes ingest and digest food caught by the choanocyte collars and transport nutrients to the other cells of the sponge. In some sponges, archaeocytes develop into gametes.
Answer:

Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
