Answer:
They lack a nucleus, but they do have ribosomes.
Explanation:
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Taxonomic rank is the relative level of a group of organism
Answer:
List of options to choose from to complete the question:
A. Aneuploidy
B. Polyploidy
C. Translocation
D. Monosomy
E. Duplication
The CORRECT ANSWER IS A.
A. Aneuploidy.
Explanation:
Aneuploidy results from unusual number of chromosomes in a cell, e.g a human cell with 45 or 47 chromosomes other than 46.
It's mostly seen in Trisomy e.g. trisomy 21 (Down syndrome), trisomy 13 (Patau syndrome) and trisomy 18 (Edwards syndrome).
Answer:
Protist, animal, and plant are all eukaryotic cells and thus they all contain a nucleus and other membrane-bound organelles in them
Three structures which are common in potist, animal, and plant cell are:
Cell membrane: It is usually a lipid bilayer structure which separates the cellular content from the surrounding environment.
Nucleus: It is double membrane-bound organelle present in all eukaryotic cells. It contains the genetic material of the cell.
Ribosome: It is a small particle made up of RNA and protein. It is generally present in multiple numbers in the cytoplasm of all living cells. It provides the site for protein synthesis.
I’m not sure but I think it is evolution.
