Explain how a teenager's frontal lobe is different from an adult's frontal lobe and how this can affect a teenager's response in an intense situation.
A teenager's frontal lobe is not fully developed yet and an adult's is. Therefore, when a teenager is in an intense situation, they aren't able to use logic and reason and instead rely on the flight/fight instincts of the brain stem.

A genetic trait is considered ___________ if it is expressed in a person who has two copies of the mutant gene associated with the trait, one from each parent.
Recessive

What is the correct test recommendation for Huntington's disease?
Genetic test

What does the brain stem control?
Basic body functions: Heart rate, breathing, blood pressure, consciousness, flight or fight instincts

Explain the functional difference between the cerebrum and the cerebellum.
The cerebrum controls learning, memory, and emotion.
The cerebellum controls balance/equilibrium and muscle coordination.

Why is it important that alkaloids taste bitter to us?
Alkaloids are found in most poisons. Therefore, when we reject/don't like the bitter flavor of alkaloids, our body is protecting us from ingesting poisons.

Daily Double: Explain/describe/draw the process of how the thalamus works with the senses and lobes to help you make sense of your environment.
Senses/nerves collect stimuli.
Thalamus decides what information is important and what's not.
The thalamus sends the important information to the lobes for processing.
