Answer: Phenylalanine has no polar group in the side chain
Explanation:
Unlike phenylanine with a nonpolar methyl benzyl group in its side chain, tryptothan and tyrosine on the other hand possesses a polar indole ring and hydroxyl group in their side chain respectively, which helps them form hydrogen bonds with water molecules.
Thus, both are less hydrophobic (water-hating) than phenylanine.

The correct answer is A. Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.
Explanation:
In the scientific method and science, the correct term to define the explanation proposed by a scientist about the phenomenon or event he wants to study is a hypothesis. On the other hand, the term theory in science is used to refer to explanations that have been repeatedly proved or confirmed. This implies the idea "cigarette smoke will influence web-building in spiders" in Robert's experiment is a hypothesis and not a theory and therefore, the statement "Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders" contains an incorrect use of a scientific term.
