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.

<span>The nucleolus is the structure within the nucleus of eukaryotic cells. It consists of RNA, DNA, and proteins. The nucleolus is involved in ribosome biogenesis which results in the synthesis of ribosomes. Ribosomal RNA (rRNA) is transcribed from DNA in the nucleolus. rRNA is processed into three mature RNAs and together with proteins form ribosomal subunits. After subunits form the ribosomes, they are transported out of the nucleus to the cytoplasm where they take place in translation.</span>
