Why might a researcher use a sample rather than an entire population for their study?

• Using a sample is more accurate than using an entire population.

• Using a sample is more practical than using an entire population.

• Using a sample is more respected than using an entire population.

• Using a sample is more complicated than using an entire population.

Which statement best describes rock deformation?

• It is a change in temperature.

• It is a change in color.

• It is a change in composition.

What is the job of the human body's pulmonary circuit?

• To pump the blood through your blood vessels.

• To supply your body with nutrients needed for cellular activity.

• To carry oxygen to the trillions of cells in your body.

• To carry blood to the lungs so carbon dioxide can be released and oxygen can be picked up.

• To return deoxygenated blood to the heart.

Which part of the cell is a series of compartments that work together to package, label, and ship proteins and molecules?

• The endomembrane system

• The nucleus

• The ribosomes

• The mitochondria

If we plug 2 in for x in the following expressions, they both give the same answer: 2x² - 1 and 3x² ÷ 2. Although both expressions yield the same solution in this case, why are they NOT equivalent?

• The number 2 is a good test for equivalence of expressions.

• They only use one variable.

• They do not use the same mathematical operation.

• The expressions are not simplifications of each other, so they don't yield identical solutions for all values.
