Q: Weight refers to what force acting on a mass? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - electronic - magnetic - solar - gravitational A:
(Answer)
gravitational

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? Read this paragraph and choose the correct option from the provided answers: 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:. Choices: - curb systems - stream systems - compound systems - buffer systems A:
(A).
buffer systems

Ques:Q: Sudden changes in geologic and climatic conditions can spur what process? Read this paragraph and choose the correct option from the provided answers: 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. Choices: - generation - cloning - symbiosis - evolution A:

Ans:evolution
