Answer:
Ribosomes are macromolecular machines, found within all living cells, that perform biological protein synthesis. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
Explanation:
Answer:
A frameshift mutation.
Explanation:
A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.
In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.
The TRUE statements are 'proteins often have more than one transmembrane domain'; 'they are regions of a transmembrane protein that actually pass through the lipid bilayer' and 'they are usually shaped like alpha-helices'.
A transmembrane domain is a membrane-spanning region within a protein. The transmembrane domains are hydrophobic regions that can be inserted into the cell membrane.
The transmembrane domains are usually shaped like alpha-helices.
This secondary structure (alpha-helices) causes the amino acid R-groups to project radially, thereby these side chains can interact with each other.
Proteins need only a single transmembrane domain to be anchored to the membrane, but they often have more than one.
For example, Acyl-coenzyme A cholesterol acyltransferases 1 and 2 (ACAT1 and ACAT2) have multiple transmembrane domains.
The transmembrane domains are regions of a transmembrane protein that actually pass through the lipid bilayer.
These domains contain amino acids with hydrophobic R-groups that pass through the membrane and interact with the hydrophobic tails of the fatty acid chains present in the lipid bilayer.
The transmembrane domains anchor transmembrane proteins to the lipid bilayer.
The interactions between amino acids of the transmembrane domains and fatty acids in the lipid bilayer help to anchor transmembrane proteins and stabilize the cell membrane.

I would say C. Reduce climate change because taking a car/vehicle results in the earth becoming polluted which leads to climate change.
*EXPLANATION*
Riding your bike or walking will not do anything to help people chopping down trees, people giving birth to more and more children nor will increase the amount of animals/organisms we have on our planet.
