Problem:OPTIONS:
- variation momentum
- magnetic momentum
- horizontal momentum
- linear momentum

Answer the following question given this paragraph: 8.1 Linear Momentum and Force Linear Momentum The scientific definition of linear momentum is consistent with most people's intuitive understanding of momentum: a large, fastmoving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as. Q: The product of a system's mass multiplied by its velocity is called what? A:
****
A: linear momentum

Answer the following question given this paragraph: Figure 18.7 Zinc is an active transition metal. It dissolves in hydrochloric acid, forming a solution of colorless Zn 2+ ions, Cl ions, and hydrogen gas. Q: Zinc is what kind of metal.? A:
OPTIONS:
- active flow metal
- active move metal
- passive stagnant metal
- active transition metal
active transition metal

Answer the following question given this paragraph: Cycle of Sexual Reproduction. Sexual reproduction involves the production of haploid gametes by meiosis. This is followed by fertilization and the formation of a diploid zygote. The number of chromosomes in a gamete is represented by the letter n. Why does the zygote have 2n, or twice as many, chromosomes?. Q: Sexual reproduction involves the production of haploid gametes by what? A:
OPTIONS:
- lesions
- mutations
- mitosis
- meiosis

Answer: meiosis

Question: Answer the following question given this paragraph: Ketones are carbonyls in which the carbon atom makes single bonds with two other carbon atoms. Ketones are less reactive than aldehydes and are a common component in nail polish removers and paint strippers. Q: What word describes a carbonyl where the carbon atom makes single bonds with two others? A:
OPTIONS:
- acetone
- ions
- photons
- ketones
Answer: ketones

input with options: Answer the following question given this paragraph: CHAPTER REVIEW 3.1 The Cell Membrane The cell membrane provides a barrier around the cell, separating its internal components from the extracellular environment. It is composed of a phospholipid bilayer, with hydrophobic internal lipid "tails" and hydrophilic external phosphate "heads. " Various membrane proteins are scattered throughout the bilayer, both inserted within it and attached to it peripherally. The cell membrane is selectively permeable, allowing only a limited number of materials to diffuse through its lipid bilayer. All materials that cross the membrane do so using passive (non energy-requiring) or active (energy-requiring) transport processes. During passive transport, materials move by simple diffusion or by facilitated diffusion through the membrane, down their concentration gradient. Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their concentration gradient. Active transport may take place with the help of protein pumps or through the use of vesicles. Q: How does a cell's membrane keep extracellular materials from mixing with it's internal components? A:
OPTIONS:
- absorbs extracellular materials
- repels extracellular materials
- destroys extracellular materials
- provides a barrier
output: provides a barrier

Problem: OPTIONS:
- electron shell
- mixture
- gas
- solid
