Answer:
Snakes slither to move around because they have no legs. They rely on their muscles and scales... The scales drag against the ground to help move the snack forward. Finch said that a snack 's strong muscles help it lift some scales and allow it to move allow rough surfaces like branches and trees.

Answer:
The correct answer is a and e.
Explanation:
Translation is the process by which mRNA is translated into proteins. It occurs in both prokaryotes and eukaryotes. In prokaryotes, transcription and translation occur simultaneously while in eukaryotes translation is a separate process occurs in the cytoplasm after transcription.
The first amino acid incorporated in the polypeptide is methionine in eukaryotes and formyl methionine in prokaryotes. After protein synthesis in both eukaryotes in prokaryotes, post-translational takes place like glycosylation, acetylation, alkylation, etc.
Post translation is important for proteins to provide them heterogeneity and functional activity. Thus, the correct answer is a. the first methionine in eukaryotic translation contains a formyl group and e. many eukaryotic proteins are chemically modified after translation, which is a much rarer phenomenon in prokaryotes.
Answer:
Fossil fuels
Explanation:
The definition of "fossil fuel" is "a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms"
Answer: The main similarity between the serine protease and aspartic protease is that these enzymes catalyze the break down or hydrolysis of the peptide bonds.
Explanation:
Serine protease structure has a triad of histidine, serine, and aspartic acid that are joined with the hydrogen bonds. Aspartic protease has a structure which includes the two aspartic acid residues which attack the peptide bond.
Serine protease catalyzes the hydrolysis of the peptide bonds with the the help of two tetrahedral intermediates, whereas the aspartic protease abstracts the proton from water molecule it results in nucleophilic attack on the carbonyl atom of carbon resulting in breakage of peptide bond.
