5. Which of the following does NOT explain a process involved in detection of internal and externals by the central nervous system? (2 points)

Motor neurons transmit signals from sensory neurons to the brain or ganglia.

Neurotransmitters pass information from presynaptic cells to postsynaptic cells.

Sensory organs carry information to the central nervous system via sensory neurons.

The dendrites of neurons receive signals from the axons of other neurons.
16.
Which of the following best describes how the nervous system in an animal transmits information to produce a response? (2 points)

Axons receive information from stimuli and then pass the information through dendrites to the brain or ganglia.

Motor neurons carry signals from the central nervous system to muscle cells to cause contractions.

Interneurons send information from postsynaptic cells to presynaptic cells to activate reflex arcs.

Sensory neurons transfer signals from the brain to the peripheral nervous system and then to sensory organs.
17.
Which of the following best describes how the brain functions in coordinating movement in vertebrates? (2 points)

The cerebellum receives sensory information about joints and muscles and integrates it.

The cerebrum sorts signals from the hypothalamus and transmits them to motor neurons.

The medulla oblongata receives and processes signals about the relative positions of muscles.

The thalamus processes motor information from the cerebrum and sorts it for processing.
18.
Explain how the rapid reproduction of many prokaryotic organisms contributes to genetic variations within the population. (5 points)

20.
A student claims the phosphorylation cascade is not a necessary function of the signal transduction pathway in determining if a cellular response will occur. Is the student correct? Justify your response with a specific scientific example. (5 points)

21.
Some types of brain injury can cause damage to the cerebellum. How would cerebellar damage affect the ability of the nervous system to receive and transmit information? Describe symptoms you would most likely find in an individual with cerebellar damage and explain why. (5 points)
