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.

dangina [55]

Answer:

A) Proportion of females with the trait is less than 8%

B) Proportion of females that would be carriers is greater than 8%

Explanation:

Only the 8% male sufferers can give their diseased X-chromosome for the female XX to be formed. hence, the proportion of the female carriers is most likely greater than 8%

On the other hand, the proportion of female sufferers will be definitely less than 8%, for 92% of the remaining male population are neither carriers nor sufferers; and the 8% male sufferers are strictly needed to give the disease X-chromosome for a female to have the trait XX.

A covalent bond is likely to be polar if _____________
Sidana [21]

Answer:

The correct answer d. one of the atoms sharing electrons is much more electronegative.

Explanation:

If one of the atoms is more electronegative than the others, like the oxygen in the water molecule, it will allow this atom to attract the other's electrons turning itself into a negative pole and turning the others into a positive pole. In the water, oxygen is more electronegative and that's why it becomes the negative part and the hydrogens become the positive.
