Ques: Answer the following question given this paragraph: In a red supergiant, fusion does not stop. Lighter atoms fuse into heavier atoms. Eventually iron atoms form. Q: Atoms of what element ultimately form in a red supergiant? Choices: - gold - steel - coal - iron A:
Ans: iron
(Q).
Answer the following question given this paragraph: Remember that a phase change depends on the direction of the heat transfer. If heat transfers in, solids become liquids, and liquids become solids at the melting and boiling points, respectively. If heat transfers out, liquids solidify, and gases condense into liquids. Q: What type of direction does a phase change depend on? Choices: - weight transfer - power transfer - humidity transfer - heat transfer A:
(A).
heat transfer
Ques:Answer the following question given this paragraph: Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. Figure 4.22 shows how intermediate filaments create a supportive scaffolding inside the cell. The intermediate filaments are the most diverse group of cytoskeletal elements. Several types of fibrous proteins are found in the intermediate filaments. You are probably most familiar with keratin, the fibrous protein that strengthens your hair, nails, and the epidermis of the skin. Q: What is the most familiar fibrous protein found in your body? Choices: - cellulose - Actin - Collagen - keratin A:

Ans:keratin
Question: Answer the following question given this paragraph: The Chemistry of Carbon What makes organic compounds ubiquitous is the chemistry of their carbon core. Recall that carbon atoms have four electrons in their valence shell, and that the octet rule dictates that atoms tend to react in such a way as to complete their valence shell with eight electrons. Carbon atoms do not complete their valence shells by donating or accepting four electrons. Instead, they readily share electrons via covalent bonds. Q: What makes organic compounds ubiquitous is the chemistry of their what? Choices: - carbon shell - dioxide shell - dioxide core - carbon core A:
Answer:
carbon core
