Two parents have identical genotypes for both hair and eye color. Their offspring does not have the same hair or eye color as the parents. The following conclusion can be made about the parent's genotype: A. One must be dominant and one must be recessive. B. Both parents must display the recessive allele. C. The parents are homozygotes. D. The parents are heterozygotes.
What is D. the parents are heterozygotes.

Rebecca's science teacher loves to have the students in the class conduct experiments. On Monday, they did a chemistry experiment in which they measured and examined different chemicals. The teacher made Rebecca and her classmates wear both safety goggles and gloves. On Wednesday, they conducted a physics experiment that tested how high balls made of different substances bounce. However, on Wednesday everyone only had to wear safety goggles. Rebecca's teacher made the students take different safety precautions on different days is:
What is the dangers are not similar in the two experiments so they require different precautions.

In physics class, your friend designs and conducts an experiment in order to determine whether the shape of an object affects how fast it falls to the ground when dropped out of a second floor window. You find the results very interesting and would like to repeat the experiment yourself. The most useful thing for you to do would be: A. your friend's notes taken during the experiment B. a box of the objects dropped C. your friend's hypothesis D. the window from which your friend dropped the objects
What is A. your friend's notes taken during the experiment.

Imagine that you are standing on the sidewalk and a bus goes by traveling at 20 mph. To you, the bus driver is moving 20 mph. However, to someone sitting on the bus, the bus driver doesn't appear to be moving at all. This is because:
What is A. motion only exists in comparison to a reference point.
