Okay, to start off, the basic difference between prokaryotic cells and eukaryotic cells is prokaryotic cells are cells without a nucleus, and eukaryotic cells are cells that contain a nucleus.
So based off that information alone, you can answer #1. Cell A does not have a nucleus (big circle shape), while Cell B does. Therefore, Cell A is the prokaryotic cell.
As for #2, prokaryotic cells and eukaryotic cells DO have similarities despite their differences. For instance, they both have some of the same organelles, like the plasma membrane, ribosomes, cytoplasm, and DNA.
Finally for #3, two differences are that #1, prokaryotic cells have nucleoids while eukaryotic cells have a nucleus, and #2, prokaryotes have circular DNA while eukaryotes have linear DNA.
Your best bet is finding a visual aid in a textbook or online to help you, so you can better identify organelles and eukaryotic/prokaryotic cells. Also, there are some cheesy videos out there on YouTube which I was forced to sit through in Bio class last year such as the Amoeba Sister's youtube channel which could help. Hope this helped!

Answer:
Tolerance
Explanation:
Tolerance is the capacity of an organism to survive changes in certain environmental and biochemical conditions. It has to with changes an organism is able to withstand when is subjected to certain factors which can biotic or abiotic.
For example, in the consumption of alcohol, tolerance can occur when there is a fast elimination of alcohol from the body system. This is usually as a result of the activation of a group of enzymes that is responsible for the metabolism of alcohol in excessive alcohol drinkers. The activation of this enzymes increases the catabolism of alcohol and hence reduces the active time within the body, hence reducing the time by which alcohol intoxicates.
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
