Function. There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption ofnutrients in the lumen. There are alsoenzymes (enterocyte digestive enzyme) on the surface for digestion.

What purpose does a fish ladder serve?

Whitepunk [10]

Answer: Option A

Explanation :

A fish ladder is also known as fish steps, fish pass or fishway.

It is built around waterfalls, dams and locks.

The purpose of building a fish ladder is to facilitate the natural migration of diadromous fishes.

A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.

Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.

What major organelle are prokaryotes missing that eukaryotes have?

djyliett [7]

Answer:

Nucleus

Explanation:

Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.

So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.

So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.
