Answer the following question given this paragraph: Protozoa can be classified on the basis of how they move. As shown in Table below , protozoa move in three different ways. Only sporozoa cannot move. Note that this classification is based only on differences in movement. It does not represent phylogenetic relationships. Q: Protozoa can be classified on the basis of how they? A:

OPTIONS:
- smell
- look
- feel
- move

Answer: move

Problem: OPTIONS:
- generalized behaviors
- diverse behaviors
- learned behaviors
- innate behaviors
Q: Answer the following question given this paragraph: Behaviors that are closely controlled by genes with little or no environmental influence are called innate behaviors . These are behaviors that occur naturally in all members of a species whenever they are exposed to a certain stimulus . Innate behaviors do not have to be learned or practiced. They are also called instinctive behaviors. An instinct is the ability of an animal to perform a behavior the first time it is exposed to the proper stimulus. For example, a dog will drool the first timeand every timeit is exposed to food. Q: Behaviors that are closely controlled by genes and have little to no environmental influence are called what kinds of behaviors? A:
Answer: innate behaviors

Problem:OPTIONS:
- synthesis impulses
- myelin impulses
- calcium impulses
- nerve impulses

Answer the following question given this paragraph: The cell body contains the nucleus and other organelles. Dendrites and axons connect to the cell body, similar to rays coming off of the sun. Dendrites receive nerve impulses from other cells. Axons pass the nerve impulses on to other cells. A single neuron may have thousands of dendrites, so it can communicate with thousands of other cells but only one axon. The axon is covered with a myelin sheath , a fatty layer that insulates the axon and allows the electrical signal to travel much more quickly. The node of Ranvier is any gap within the myelin sheath exposing the axon, and it allows even faster transmission of a signal. Q: Axons pass what on to other cells? A:
****
A: nerve impulses

Answer the following question given this paragraph: Kinetic friction acts between two surfaces that are in contact and in motion with respect to each other. This force reduces the acceleration and it always opposes the direction of motion. Q: What type of force always opposes the direction of motion? A:
OPTIONS:
- binary friction
- strong force
- harmonic friction
- kinetic friction
kinetic friction

Answer the following question given this paragraph: What is physics ? Physics is the branch of science that studies the physical world, including objects as small as subatomic particles and as large as galaxies. It studies the nature of matter and energy and how they interact. Physicists are inquisitive people who want to know the causes of what they see. How does the moon move? Why does the moon move? Why do the stars shine? Why do your hands get warm when you rub them together? Physicists, like all scientists, hope to find explanations that describe more than one phenomenon and offer a better understanding of how the universe works. Q: What is the branch of science that studies the physical world? A:
OPTIONS:
- social science
- botany
- Ecology
- physics

Answer:
physics
