1. B

2. E

3. P

4. E

5. B

6. B

7. B

8. E

9. E

10. E

Explanation:

1. Both prokaryotes and eukaryotes have a cell membrane. Hence, it is B

2. Only eukaryotes have a nucleus. Hence, it is E

3. Bacteria are an example of prokaryotes because they lack a membrane-bound nucleus. Hence, P

4. Animals are an example of eukaryotes because they possess a membrane-bound nucleus. Hence, E

5. Both prokaryotic and eukaryotic cells contain ribosomes. Hence, B.

6. Both prokaryotes and eukaryotes contain cytoplasm. Hence, B.

7. Both prokaryotes and eukaryotes contain genetic material, such as DNA. Hence, B

8. Only eukaryotes contain membrane-bound organelles e.g mitochondrion, endoplasmic reticulum. Hence, E.

9. Plants are an example of eukaryotes because they possess a membrane-bound nucleus. Hence, E.

10. My body cells as a human being are made of eukaryotic cells. Hence, E.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
