1 answer:

7 0

A. Hershey and Chase used bacteriophages to confirm that DNA was the genetic material in genes.

According to the central dogma of molecular biology, the process of protein synthesis in living organisms follows the order: DNA →RNA→ Protein.Information for synthesis of a particular protein is copied (transcribed) from DNA onto mRNA in a process called transcription, in the cell nucleus.mRNA (messenger RNA) leaves the cell nucleus and enters the cytoplasm where it attaches to a ribosome. tRNA (transfer RNA) begins to decode (translate) the information on the attached mRNA in a process called translation and fetches amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed.

Describe how is an organism's food and habitat related

Brums [2.3K]

As we already know, organism mean's something that is living.
Well, at a habitat there is going to be some animal's or insect's because it's that animal's or insect's habitat. ( They live there.) Well most organism's are food.
( NOTICE I bloldfaced "most", this is because not all organism's are food) Okay, let's go over what we just said. Organism's are living thing's and habitat's are places where organism's live. Now we have to think about this, you stated, Describe how is an organism's food and habitat related. The one thing we have not talked about is, organism's food. Okay, Animal's live in habitat's and so do organism's.
( Remember, some organism's eat other organism's) This is how organism's food and habitat are related.

Hope this help's!
Good luck on your

Hello there!!!

I'm inclined to think that the answer is A. These are products, so they can't really be reactants (unless the equation is reversible, which this is not). Cellular respiration is the process of the cells releasing the waste that they do not need. So A seems to be the logical choice.
