ATI TEAS Science Questions

1. Which of the following statements is not true about the relationship between the gastrointestinal system and the endocrine system?

Correct answer: D

Rationale: The gastrointestinal system and the endocrine system are closely interconnected. Hormones released by the endocrine system play a crucial role in signaling hunger or fullness, regulating blood glucose levels, and stimulating digestive processes like enzyme secretion and peristalsis for efficient food digestion. Option D, stating 'All of the above are true,' is incorrect in the context of the question because there is a need to identify the statement that is not true about the relationship between the gastrointestinal system and the endocrine system. Choices A, B, and C are all correct statements that reflect the close relationship and interactions between the gastrointestinal and endocrine systems.

2. What is the role of the pancreas in regulating blood sugar levels?

Correct answer: B

Rationale: The correct answer is B. The pancreas plays a crucial role in regulating blood sugar levels by producing both insulin and glucagon. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the release of stored glucose into the bloodstream. Choice A is incorrect because the pancreas produces both insulin and glucagon. Choice C is incorrect because the pancreas does not store glucose; instead, it regulates glucose levels. Choice D is incorrect because adrenaline is produced by the adrenal glands, not the pancreas, and is not directly involved in regulating blood sugar levels.

3. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?

Correct answer: A

Rationale: The correct answer is the dorsal root. The dorsal root of the spinal cord contains sensory nerve fibers that transmit sensory information from the body to the brain. This information includes touch, pain, temperature, and proprioception. The ventral root, on the other hand, contains motor nerve fibers responsible for carrying signals from the brain to the muscles and glands, controlling movement and glandular functions. Gray matter, consisting mainly of cell bodies, is involved in processing and integrating sensory and motor information within the spinal cord. White matter is primarily composed of myelinated axons that facilitate communication between different regions of the nervous system, allowing signals to travel efficiently within the spinal cord and between the brain and other parts of the body. Therefore, the dorsal root is specifically associated with transmitting sensory information, making it the correct answer in this context.

4. Which of the following scenarios represents an example of static friction?

Correct answer: C

Rationale: The correct answer is C. Static friction occurs when two surfaces are in contact but not moving relative to each other. Pushing a stationary object involves static friction as you apply a force to overcome the friction keeping the object stationary. Choices A, B, and D involve kinetic friction, which occurs when two surfaces are moving relative to each other. Option A involves moving the box across the floor, which is an example of kinetic friction. Option B involves the movement of a car around a curve, which also relates to kinetic friction due to the relative movement between the tires and the road. Option D describes braking a car to stop, where the moving car's wheels interact with the road, creating kinetic friction to slow down and stop the car.

5. Which organelle is responsible for storing genetic material?

Correct answer: B

Rationale: The correct answer is the Nucleus. The nucleus is responsible for storing genetic material (DNA) and controlling cell functions. Mitochondria are known for energy production, not genetic storage. Ribosomes are involved in protein synthesis, not genetic material storage. The endoplasmic reticulum is involved in protein and lipid synthesis, not genetic material storage. Therefore, the nucleus is the organelle primarily responsible for housing the genetic material within a cell.
