What causes rough endoplasmic reticulum to look “rough” under a microscope?

a rough er has lots of surface area.

b rough er has many membrane packages.

c rough er makes lipids.

d rough er has ribosomes attached to it.

Correct answer is D.

Explanation:

Rough endoplasmic reticulum looks "rough" (see first picture) under electron microscope compared to the smooth endoplasmic reticulum (see second picture). The small grayish/black dots are the ribosomes attached to the ER, helping with the translation of  RNA to protein.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
