What happens to the brain’s size change caused by Alzheimer's?
The brain becomes much larger in certain areas, compensating for lost neurons.
The brain's size remains unchanged, and only the neurons are affected.
The brain shrinks, particularly in regions responsible for memory and cognitive function.
Shrinking due to neuron damage and death

In a gene for a certain protein, a mutation changes an adenine nucleotide to a guanine nucleotide. This results in the substitution of a nonpolar amino acid with a charged amino acid. Which of the following is most likely the effect of this mutation on protein function?
The protein will fold correctly and maintain full functionality.
The mutation will lead to a frameshift, altering all downstream amino acids.
The altered amino acid could disrupt protein folding and lead to aggregation.
The protein will be degraded immediately, regardless of the cellular environment.
The altered amino acid could disrupt protein folding and lead to aggregation.
