Anatomy

1. Damage to which part of the brain can lead to difficulty with language and speech?

Correct answer: A

Rationale: The correct answer is A: Broca's area. Broca's area, located in the frontal lobe of the brain, is crucial for language production. Damage to Broca's area can result in expressive aphasia, where individuals have difficulty speaking fluently and forming coherent sentences. Wernicke's area, located in the temporal lobe, is responsible for understanding and interpreting language. Damage to Wernicke's area can lead to receptive aphasia, where individuals have difficulty understanding language. The occipital lobe is primarily responsible for processing visual information, while the cerebellum is involved in motor coordination and balance, not language and speech.

2. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

3. The final sentence suggests that users should approach social media with a healthy dose of

Correct answer: B

Rationale: The emphasis on "critical thinking" and "skepticism" suggests the importance of approaching social media with a cautious and discerning mind, aligning with B

4. What happens to the density of a gas when its temperature increases at constant pressure?

Correct answer: B

Rationale: As gas particles gain thermal energy with increasing temperature, they spread out, decreasing the density.

5. Which hormone, produced by the adrenal glands, prepares the body for a "fight or flight" response by increasing heart rate, dilating airways, and mobilizing energy stores?

Correct answer: c

Rationale: The correct answer is C: Epinephrine. Epinephrine, also known as adrenaline, is the hormone produced by the adrenal glands that prepares the body for a 'fight or flight' response. It increases heart rate to pump more blood to muscles, dilates airways to improve oxygen intake, and mobilizes energy stores to provide immediate fuel for physical activity. Cortisol is a hormone involved in stress response and metabolism regulation, but it does not directly trigger the rapid physiological changes associated with 'fight or flight.' Aldosterone regulates salt and water balance, while insulin regulates blood sugar levels, neither of which are directly involved in preparing the body for a rapid response to danger or stress.

6. What type of inheritance pattern results in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation?

Correct answer: D

Rationale: Rationale: A) Incomplete dominance: In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes. This does not result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. B) Codominance: In codominance, both alleles are fully expressed in the heterozygous phenotype. This also does not result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. C) Sex-linked inheritance: Sex-linked inheritance involves genes located on the sex chromosomes and does not typically result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. D) Autosomal dominant inheritance: In autosomal dominant inheritance, a single copy of the dominant allele is sufficient to express the dominant phenotype. When a heterozygous individual (Aa) is crossed with another
