eukaryotic cells and prokaryotic cells differs in presence of nuclear membrane structure, membrane bound organelles and size of ribosomes.
prokaryotic cells are unicellular structure with smaller size. They do not have well defined nucleus and membrane bound organelles like endoplasmic reticulum, mitochondria, chloroplast, etc. They have smaller ribosomes and simpler flagella. They also have plasmid in the cytoplasm.
Eurkaryotic cell bigger in size. They have well-defined nucleus with membrane bound organelles like endoplasmic reticulum, mitochondria, chloroplast, etc. They have bigger ribosomes and complex flagellar structure. They rarely have plasmid in cytoplasm.

Answer:
NO!! you trying to kill off the human race or worse?
This is most likely an example of a mutation.
Mutation is any alteration or change in DNA sequence which affects the genetic instruction carried by that gene. Mutation can occur either as a result of errors during DNA replication or due to environmental factors such as cigarette smoke and ultraviolet (UV) radiation. Mutations are heritable, especially if they have a positive effect. The disorder Down syndrome is an example of mutation which occurs due to error in cell division in which there is extra copy of a genetic material (specific chromosome); chromosome 21.
Answer is A, in asexual reproduction there is less genetic variation because it will be an exact copy of the parent organism
Cosmic background radiation, it shows that the universe is still expanding because of the big bang theory. God I love science.
