DNA and RNA serve what purpose within a cell and living things.

Biology
1 answer:
Lorico [155]3 years ago
4 0

Answer:

D. DNA Contains the genetic code / instructions for the cell and the living organism they build

Explanation:

DNA and RNA are nucleic acids that contain the genetic information so that a cell knows exactly what proteins it should make, what function it should serve.

Why not A: DNA and RNA don't strictly build cellular proteins; that job is up more to the ribosome, tRNA, and mRNA. While this could be acceptable, it's not as good an answer as D.

Why not B: This is incorrect.

Why not C: DNA and RNA don't do any of the dirty work of fighting off intruders; that's the job of the immune system, building antibodies, eating the viruses with white blood cells, and using the epidermis as a barrier to keep harmful things out.

Explain how and why hypertonic, isotonic, and hypotonic solutions affect plant and animals cells?
lesya692 [45]
When placed into an hypertonic solution, animal cells will shrivel up, while plant cells will stay firm thanks to their air-filled vacuole. In a hypotonic solution, the cells will take on water and appear more plump. In an isotonic solution, they'll stay the same.
