Answer the following question given this paragraph: The many steps in the process of aerobic cellular respiration can be divided into three stages. The first stage, glycolysis, produces ATP without oxygen. Because this part of the cellular respiration pathway is universal, biologists consider it the oldest segment. Note that glycogen and fats can also enter the glycolysis pathway. The second stage is the Krebs Cycle, and the third stage is the electron transport chain. It is during the third stage that chemiosmosis produces numerous ATP molecules. Q: Glycolysis, the krebs cycle, and the electron transport chain are stages in what process? Choices: - cell death - reproduction - mitosis - aerobic cellular respiration A:
aerobic cellular respiration

(Q).
Answer the following question given this paragraph: There are no forces of attraction or repulsion between gas particles . Attractive forces are responsible for particles of a real gas condensing together to form a liquid. It is assumed that the particles of an ideal gas have no such attractive forces. The motion of each particle is completely independent of the motion of all other particles. Q: Which measure indicates the number of electrons in a given sublevel? Choices: - subscripts - mole - coefficients - superscripts A:
(A).
superscripts
Ques:Answer the following question given this paragraph: 2.3 | Biological Molecules By the end of this section, you will be able to: Describe the ways in which carbon is critical to life Explain the impact of slight changes in amino acids on organisms Describe the four major types of biological molecules Understand the functions of the four major types of molecules The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass. Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements. Q: Biological macromolecules are organic, which means that they must contain what? Choices: - hydrogen - aluminum - oxygen - carbon A:

Ans:carbon
Question: Answer the following question given this paragraph: The cornea is the transparent outer covering of the eye. It protects the eye and also acts as a convex lens, helping to focus light that enters the eye. Q: What is the transparent outer covering of the eye? Choices: - pupil - iris - retina - cornea A:
Answer:
cornea
