Answer the following question given this paragraph: Lewis Diagrams Chemists use simple diagrams to show an atom's valence electrons and how they transfer. These diagrams have two advantages over the electron shell diagrams introduced in Chapter 2 "Elements, Atoms, and the Periodic Table". First, they show only valence electrons. Second, instead of having a circle around the chemical symbol to represent the electron shell, they have up to eight dots around the symbol; each dot. Q: Chemists use simple diagrams to show an atom's valence electrons and how they do what? Choices: - bond - react - escape - transfer A:
transfer

Ques: Answer the following question given this paragraph: the evolution of cellular respiration, which used oxygen to help harvest energy from organic molecules. Q: Cellular respiration uses oxygen to harvest what from organic molecules? Choices: - water - chlorophyll - light - energy A:
Ans: energy
(Q).
Answer the following question given this paragraph: Larger amounts of sulfur also come from hydrogen sulfide recovered during the purification of natural gas. Sulfur exists in several allotropic forms. The stable form at room temperature contains eight-membered rings, and so the true formula is S8. However, chemists commonly use S to simplify the coefficients in chemical equations; we will follow this practice in this book. Q: What does the stable form of sulfur at room temperature contain? Choices: - six - membered rings - four - membered rings - electron shell - eight-membered rings A:
(A).
eight-membered rings
Ques:Answer the following question given this paragraph: In eukaryotic cells, the start of transcription is one of the most complicated parts of gene regulation. There may be many regulatory proteins and regulatory elements involved. Regulation may also involve enhancers. Enhancers are distant regions of DNA that can loop back to interact with a gene's promoter. Q: Which is one of the most complicated parts of gene regulation in eukaryotic cells? Choices: - middle of transcription - aftermath of transcription - end of transcription - start of transcription A:

Ans:start of transcription
Answer the following question given this paragraph: Your own body cells burn fuel in combustion reactions. The fuel is glucose (C 6 H 12 O 6 ), a simple sugar. The process in which combustion of glucose occurs in body cells is called cellular respiration. This combustion reaction provides energy for life processes. Cellular respiration can be summed up by the equation:. Q: Cellular respiration in humans involves the combustion of what simple sugar? Choices: - starch - glutamate - insulin - glucose A:
glucose
