Though both are unicellular, bacteria doesn't possess a nucleus or cell organelles, except ribosomes, whereas amoebas  possess a well-defined nucleus and all essential cell organelles.

Explanation:

Eukaryotes and prokaryotes have the most significant difference between them. Eukaryotes have organelles that are membrane-bound and have a nucleus. Prokaryotes do not have these specific features.  Eukaryotes can be both multicellular and unicellular and prokaryotes are unicellular.

Bacteria are an example of prokaryotes as it doesn’t have nucleus and organelles that are membrane bound. As it is small in shape it can function without organelles. Amoeba is an example of eukaryotic cell as it is unicellular and has all necessary organelles and has a nucleus.

Lubov Fominskaja [6]
The defining characteristic of the intertidal zone is that it is submerged with water during high tide and exposed to the air during low tide. The zone can take many forms, from sandy beaches to rocky cliffs. It is common for the intertidal zone to change frequently, since it is constantly battered by crashing waves.

Genetic variation in bacterial populations cannot result from
zmey [24]

Answer:

Meiosis

Explanation:

Gene recombination refers to the mixture of genes from different individuals that occurs during sexual reproduction. Gene recombination is responsible for mixing between genes, which results in genetic variation in a bacterial population.

Genetic variability in a bacterial population occurs through three types of mechanisms: transformation, conjugation and transduction. However this genetic variation does not occur through Meiosis.

Transformation is the incorporation of free DNA by the bacterial cell. Conjugation is the process of transferring DNA from one bacterium to another, involving contact between the two cells. Transduction is the transfer of genetic material between cells, mediated by bacteriophages.
