Accepted Answer

Exchange reaction

Question 4

Which tissue type is characterized by cells embedded in a matrix containing fibers and ground substance, and is responsible for support and protection?

Accepted Answer

Connective tissue

Question 5

A fracture in the shaft of a long bone will primarily affect which process?

Accepted Answer

Question 6

According to Wolff's law, what happens to bone tissue in response to increased mechanical stress?

Accepted Answer

Bone tissue becomes thicker and stronger.

Question 7

Which bone in the axial skeleton does NOT articulate with any other bone?

Accepted Answer

Hyoid

Question 8

A synovial joint is classified structurally by the presence of a joint cavity. Functionally, which type of movement does it allow?

Accepted Answer

Diarthrosis (freely movable)

Question 9

Which of the following is a real-life example of a positive feedback mechanism?

Accepted Answer

Oligodendrocyte

Question 15

Which equation best represents a dehydration synthesis reaction?

Accepted Answer

$$ \mathrm{A} + \mathrm{B} \rightarrow \mathrm{AB} + \mathrm{H}_2\mathrm{O} $$

Question 16

Which of the following best describes the difference between the somatic and autonomic nervous systems?

Accepted Answer

Somatic uses one motor neuron to reach the effector; autonomic uses two.

Question 17

Which lobe of the cerebrum is primarily responsible for processing visual information?

Accepted Answer

Occipital lobe

Question 18

A reflex arc typically includes which sequence of components?

Accepted Answer

Sensory receptor, sensory neuron, interneuron, motor neuron, effector

Question 19

Which of the following best explains why axonal regeneration is more successful in the PNS than in the CNS?

Accepted Answer

Schwann cells in the PNS form regeneration tubes, while oligodendrocytes in the CNS do not.
