ATI TEAS Science Questions

1. Anya was paid by Company X to analyze dwindling honeybee populations in the Southwest. After measuring hive populations over several months, she noticed no patterns in the geographic distributions of the deaths after comparisons with local maps of interest. This supported her hypothesis, so she took samples of the honey and the bees from the hives and performed dozens of dissections to confirm her suspicions. Which of the following is the most likely hypothesis upon which this research was performed?

Correct answer: B

Rationale: The most likely hypothesis based on the information provided is that honeybees are contracting parasites in large droves. Anya observed no geographic patterns in hive deaths and proceeded to analyze honey and bees for further investigation. This suggests that she suspected a widespread issue affecting multiple hives simultaneously, consistent with a scenario where honeybees are being infected by parasites in high numbers, leading to dwindling populations across different locations. The other choices can be eliminated because there is no mention of aggressive species of bees from the South, no evidence pointing to pesticide sensitivity as the cause, and no indication of a correlation with cell phone towers in the information provided.

2. What enzyme plays a key role in breaking down carbohydrates in the small intestine?

Correct answer: C

Rationale: Amylase is the enzyme responsible for breaking down carbohydrates in the small intestine. It specifically targets starches and sugars, breaking them down into smaller molecules like maltose and glucose that can be absorbed by the body. Pepsin is an enzyme that breaks down proteins in the stomach, not the small intestine. Lipase is responsible for breaking down fats, not carbohydrates. Trypsin is an enzyme that breaks down proteins in the small intestine, not carbohydrates.

3. Which part of the brain is responsible for processing vision?

Correct answer: A

Rationale: The occipital lobe is the part of the brain responsible for processing visual information. Located at the back of the brain, the occipital lobe contains the primary visual cortex, which plays a crucial role in interpreting visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, decision-making, and motor control, not vision processing. The temporal lobe is responsible for auditory processing, memory, and emotion, not vision. The parietal lobe is involved in sensory integration, spatial awareness, and perception of stimuli, but not specifically for visual processing.

4. Which of the following conditions is characterized by a high percentage of CO2 and a very low percentage of O2 in the blood?

Correct answer: A

Rationale: Asphyxia is the correct answer as it refers to a condition with high CO2 and low O2 levels in the blood. Asphyxia can result in oxygen deprivation and excess carbon dioxide in the bloodstream, posing a life-threatening situation if not treated promptly. Emphysema is a chronic lung disease characterized by the damage to the air sacs in the lungs, leading to breathing difficulties. Eupnea denotes normal breathing without any abnormalities. Hypoxia, on the other hand, involves low oxygen levels reaching the body's tissues, which can result from various causes such as reduced oxygen in the air or respiratory issues.

5. Which of the following functions would be most affected by laryngeal damage?

Correct answer: C

Rationale: Laryngeal damage would most affect the function of singing. The larynx, or voice box, houses the vocal cords responsible for producing sound during singing. Damage to the larynx can impair the ability to phonate and control pitch, tone, and quality of the voice, which are crucial for singing. Choices A, B, and D are unrelated to the larynx. Blinking is controlled by the facial nerve, walking involves motor functions and coordination, and hearing is related to the ear structures and auditory nerves.
