Answer the following question given this paragraph: To return to the first image, these cars travel a distance of 500 miles over the course of the race. However, they are traveling in a circle, and the start and finish line are the same. Therefore, when the car finishes the race, it is in essentially the same position it was when it started. The car's total displacement is only a few feet. Q: In a car race on a circular track, where the start and finish line are the same, what quantity is neglible? Choices: - total acceleration - partial displacement - total distance - total displacement A:
(Answer)
total displacement

Answer the following question given this paragraph: Loggerhead turtles spend most of their life in the ocean. Adult female loggerheads go ashore briefly to lay their eggs in the sand. Then they return to the water and leave the eggs to hatch on their own. Figure below shows baby loggerheads on a beach shortly after hatching. The baby turtles must make their way back to the water, hopefully without being snatched up by a predator. Loggerhead turtles are reptiles. Unlike amphibians, turtles and other reptiles can lay their eggs on dry land. That's because they produce amniotic eggs. Amniotic eggs have waterproof membranes to prevent them from drying out. Q: Laid on dry land by reptiles, amniotic eggs have what that prevents them from drying out? Choices: - double shells - double yolks - oil coating - waterproof membranes A:
(Answer)
waterproof membranes

Answer the following question given this paragraph: Parts of a Neuron As you learned in the first section, the main part of a neuron is the cell body, which is also known as the soma (soma = "body"). The cell body contains the nucleus and most of the major organelles. But what makes neurons special is that they have many extensions of their cell membranes, which are generally referred to as processes. Neurons are usually described as having one, and only one, axona fiber that emerges from the cell body and projects to target cells. That single axon can branch repeatedly to communicate with many target cells. It is the axon that propagates the nerve impulse, which is communicated to one or more cells. The other processes of the neuron are dendrites, which receive information from other neurons at specialized areas of contact called synapses. The dendrites are usually highly branched processes, providing locations for other neurons to communicate with the cell body. Information flows through a neuron from the dendrites, across the cell body, and down the axon. This gives the neuron a polaritymeaning that information flows in this one direction. Figure 12.8 shows the relationship of these parts to one another. Q: Which part of a neuron contains the nucleus and most of the major organelles? Choices: - organ body - simple body - retinal body - cell body A:
(Answer)
cell body
