Building blokes of proteins are _____
gulaghasi [49]
The building blocks of protein are C. AMINO ACIDS.

Amino acids are made up of a center carbon atom bound positively to a charged amino group and a negatively charged carboxyl group and a side chain.

The primary structure of a protein is the sequence of an amino acids that are attached together by a peptide bond

The secondary structure of a protein,  the polypeptide is folded through the  mechanisms of amino acids rotating around bonds folding into a helix or a pleated sheet structure and stabilized by a hydrogen bond.

Why can food chains
lana66690 [7]

Answer:

A. Because energy is lost at every level.

Explanation:

energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.

Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).

This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.

Hope this helps, have a lovely day :)

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.
