TEAS 7 science practice questions

1. What is the protective sac surrounding the testes in the male reproductive system?

Correct answer: B

Rationale: The scrotum is the correct answer, as it is the protective sac surrounding the testes in the male reproductive system. The scrotum's role is crucial in maintaining the optimal temperature for proper sperm production by regulating the distance of the testes from the body. The vas deferens is a duct responsible for transporting sperm from the testes to the urethra, not the protective sac surrounding the testes. The epididymis is a coiled tube where sperm mature and are stored before ejaculation, not the protective sac. The urethra is a tube that serves as a common passageway for both urine and semen to exit the body, not the protective sac surrounding the testes.

2. Which property of matter measures the amount of space occupied by an object?

Correct answer: D

Rationale: Volume is the property of matter that measures the amount of space occupied by an object. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. Volume specifically quantifies the space occupied by an object, making it the correct answer in this context.

3. Which hormone stimulates the release of pancreatic enzymes and bile?

Correct answer: C

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone that stimulates the release of pancreatic enzymes and bile. CCK is released by the small intestine in response to the presence of fats and proteins in the duodenum, triggering the release of digestive enzymes and bile to aid in the digestion of fats and proteins. Gastrin (Choice A) primarily stimulates gastric acid secretion, not the release of pancreatic enzymes and bile. Insulin (Choice B) regulates blood sugar levels by promoting glucose uptake. Glucagon (Choice D) raises blood glucose levels by stimulating the breakdown of glycogen in the liver.

4. During REM sleep, which type of brain wave activity is often seen and associated with dreaming?

Correct answer: D

Rationale: Theta waves are the correct answer as they are often seen during REM (rapid eye movement) sleep, the stage of sleep closely related to dreaming. Theta waves have a frequency of 4-7 Hz and are typically present during deep relaxation, meditation, and light sleep stages. Delta waves (choice A) are associated with deep sleep stages, not REM sleep. Alpha waves (choice B) are present during wakefulness and relaxation but not predominantly during REM sleep. Beta waves (choice C) are associated with alertness, problem-solving, and active thinking, not specifically with REM sleep or dreaming.

5. Which type of tissue connects muscles to bones?

Correct answer: B

Rationale: The correct answer is B: Tendons. Tendons connect muscles to bones, not bones to muscles. They play a crucial role in transmitting the force generated by muscles to move bones, enabling movement. Ligaments (choice A) connect bones to bones, providing stability to joints. Cartilage (choice C) is a connective tissue found in joints, providing cushioning and flexibility. Muscles (choice D) are responsible for generating force through contraction but do not directly connect muscles to bones.
