Answer the following question given this paragraph: The terms mass and weight, while often used interchangeably, are technically different terms. Mass is the quantity of inertia possessed by an object. Weight refers to the gravitational force acting on a mass, as measured on a scale. On the surface of the earth, the numerical values of mass and the corresponding force of gravity (weight) are approximately equivalent. For now, we will use the terms mass and weight interchangeably although mass is the more appropriate scientific term. Q: Weight refers to what force acting on a mass? A:
OPTIONS:
- electronic
- magnetic
- solar
- gravitational
gravitational

Answer the following question given this paragraph: Pure metals may be less useful than mixtures of metals, called alloys. Examples of alloys include steel, bronze, and brass. Q: Steel, bronze, and brass are examples of what? A:
OPTIONS:
- oxides
- compounds
- chemicals
- alloys

Answer: alloys

Question: Answer the following question given this paragraph: Bicarbonate Bicarbonate is the second most abundant anion in the blood. Its principal function is to maintain your body's acid-base balance by being part of buffer systems. This role will be discussed in a different section. Bicarbonate ions result from a chemical reaction that starts with carbon dioxide (CO2) and water, two molecules that are produced at the end of aerobic metabolism. Only a small amount of CO2 can be dissolved in body fluids. Thus, over 90 percent of the CO2 is converted into bicarbonate ions, HCO3, through the following reactions:. Q: Bicarbonate is the second most abundant anion in the blood. its principal function is to maintain your body's acid-base balance by being part of these? A:
OPTIONS:
- curb systems
- stream systems
- compound systems
- buffer systems
Answer: buffer systems

input with options: Answer the following question given this paragraph: When geologic and climatic conditions are changing, evolution may occur more quickly. Thus, long periods of little change may be interrupted by bursts of rapid change. This model of the timing of evolution is called punctuated equilibrium . It is better supported by the fossil record than is gradualism. This model suggests that niches left open by sudden geologic and climatic changes may be rapidly filled by bursts of evolution. Q: Sudden changes in geologic and climatic conditions can spur what process? A:
OPTIONS:
- generation
- cloning
- symbiosis
- evolution
output: evolution

Q: Answer the following question given this paragraph: Q: Which gland is an extension of the hypothalamus? A:

OPTIONS:
- adrenal gland
- pineal gland
- salivary gland
- posterior pituitary gland

A: posterior pituitary gland
