Question

7 multiple choice 1 point
what is the thalamus responsible for?
relaying sensory and motor signals to the cerebral cortex
controlling balance and coordination
producing neurotransmitters
regulating body temperature

8 multiple choice 1 point
what is a mutation?
change in a gene or chromosome
the rate at which genes mutate
a type of cell division
the process of genes being passed down from parent to offspring

Explanation:

Analyze the function of the thalamus

The thalamus is a key forebrain structure. It acts as a primary relay station. It routes sensory and motor signals to the cerebral cortex.

Evaluate the options for Question 7

• Option 1 matches the relay function of the thalamus.
• Option 2 describes the cerebellum.
• Option 3 is done by neurons and specific brain nuclei.
• Option 4 describes the hypothalamus.

Define a genetic mutation

A mutation is a permanent alteration in DNA. This change occurs in a gene or chromosome.

Evaluate the options for Question 8

• Option 1 correctly defines a mutation as a change.
• Option 2 describes mutation rate.
• Option 3 describes mitosis or meiosis.
• Option 4 describes inheritance.

Answer:

Question 7

• Relaying sensory and motor signals to the cerebral cortex (Correct answer)
• Controlling balance and coordination
• Producing neurotransmitters
• Regulating body temperature

Question 8

• change in a gene or chromosome (Correct answer)
• the rate at which genes mutate
• A type of cell division
• The process of genes being passed down from parent to offspring
