Phantasy [73]

Answer:

unicellular - both prokaryotes and eukaryotes

contain mitochondrion - eukaryotes only

are generally less than 2 pm - Prokaryotes only

multicellular - eukaryotes only

lack membrane-bound organelles - prokaryotes only

Explanation:

Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.

Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.

​(f) contact a local hospital and ask them the percentage of the population that is blood type o. why might the results​ differ?
Fudgin [204]
Contacting a local hospital and asking them the percentage of the population that has blood type O will generate different results. 

The factors that we have to consider why there is differing results are:
1) location of the hospital
2) nationality of their patients
3) number of their patients

I am assuming that the population that question is referring to is the number of patients in the local hospital. The bigger the population, the smaller the effect a unit has on the whole and vice versa. 

I read an article that states that 37% of the U.S. population has O+ blood type. These people are usually of Hispanic descent or some Asian descent. So, if a hospital is in a locality that has a majority of Hispanic or Asian patients, its percentage will be higher than a hospital that is located in a Caucasian-populated area. 

Aside from Type O+ (most common), blood types also include: O-, A+, A-, B+, B-, AB+, and AB- (rarest blood type)
