The completed sentence with the correct answer is; How does the first sentence in the paragraph help to introduce the main idea. The correct answer is B.
Answer;
-On the polar end or the hydrophillic end of the protein.
Explanation;
-Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups.The R group is often referred to as the amino acid side chain.
-Side chains which have various functional groups such as acids, amides, alcohols, and Amines will impart a more polar character to the amino acid. Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine.
Therefore; serine being a polar or hydrophillic amino acid will be found on the polar side chain of the protein.
D. Brain activity doesn't necessarily cause behaviour just because they coincide.
Explanation:
- Neuroscience is the study of the neurons. This deals with how the nervous system develops, the structure of the nervous system and its actions.
- Neuroscientists are focusing on the brain and its impact on cognitive functions and behaviour.
- Scientists proved that the chemicals present in the brain are responsible for our general state and mood that we are going through. Damage of brain cell will affect our impulses and the impulsive behaviours.
Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.

It can become an ion because it can lose or gain an electron. It can become a part of molecule because it can form covalent bond with other atoms to gain a full valence shell.
