A researcher is interested in performing an experiment to determine whether listening to classical music while taking a quiz helps students do better. The researcher has two comparable classrooms with one classroom of students taking a quiz while listening to classical music and the other taking the same quiz without listening to classical music.

What is the independent variable in the experiment?

• different classrooms

• listening to classical music

• taking a quiz

• how students do on the quiz

This microorganism causes the common cold. It can only multiply when inside a human host. It is so small, it can't be seen with microscopes you would use in school, and it has the ability to mutate or change. What type of disease agent is this microorganism?

• bacteria

• virus

• fungi

• this microorganism is not a disease agent

A patient comes to the ER complaining of the following symptoms: coughing (sometimes blood), fever, chills, fatigue, weakness, pain in the chest. Based on the information, what illness does the patient most likely have?

• common cold

• influenza (Flu)

• pneumococcal pneumonia

• tuberculosis

A patient comes to you with complaints of muscle weakness, muscle spasms, and twitches in the left arm. During the exam, you notice no problems with sensation, and the patient reports no loss of sensation, no pain, no tingling, and no numbness. All neurological tests were normal, except for the nerve conduction velocity tests and EMG results.

Which of the following structure is most likely the location of the problem?

• sensory neurons

• motor neurons

• brain

• spinal cord

Which label identifies part of the central nervous system?

• A

• B

• C

• D

Which statement below describes the correct function of the central nervous system (CNS) and periphgeral nervous system (PNS)?

• The PNS functions to process input from the CNS and if necessary triggers a response to act on the input

• The CNS is responsible for connecting and triggering the muscle cells throughout the body to respond to stimuli.

• The CNS functions to process input from the PNS, and if necessary, triggers a response to act on the input.

• The CNS is responsible for receiving stimuli from the body's environment and sends them as signals to the PNS.

A neurologist has information that leads her to suspect that a patient has a brain tumor. What test should she order to confirm the diagnosis?

• a brain scan such as a CT scan or an MRL

• a spinal tap to collect cerebrospinal fluid (CSF)

• Electromyography (EMG) test

• nerve conduction velocity test

A man was involved in an accident where an iron bar shot through his left cheek, through his brain, and exited through the top of his skill. Although he lived, his friends reported that his personality was different after the accident. For example, he could no longer stick to plans and was often angry and rude, where before the accident he was a model employee and friend.

Given his change in personality, what part of the brain was damaged in this accident?

• Frontal lobe

• Occipital lobe

• Parietal lobe

• Temporal Lobe

Which sequence shows the correct order for how a signal travels through a neuron and into the next neuron chain?

• Dendrite-->cell body-->axon-->synapse-->dendrite

• Dendrite-->cell body-->synapse-->axon-->dendrite

• cell body-->dendrite-->axon-->synapse-->cell body

• dendrite-->axon-->cell body-->synapse-->cell body
