TEAS 7 science practice Questions

Question 1 of 5

Which of the following organs is NOT directly involved in urine production?

Correct Answer: B

Rationale: The correct answer is B, Urethra. The urethra is not directly involved in urine production. It is a tube that carries urine from the bladder to the outside of the body. The kidneys are responsible for filtering waste and excess substances from the blood to produce urine. The bladder stores urine until it is expelled from the body. The lungs are not involved in urine production; they are responsible for gas exchange during respiration. Choice A, Kidneys, is directly involved in urine production by filtering the blood to form urine. Choice C, Lungs, plays a role in respiration and oxygen exchange but is not directly involved in urine production. Choice D, Bladder, stores urine before it is excreted from the body and is directly involved in the final stages of urine elimination, unlike the urethra.

Question 2 of 5

Which gland, often referred to as the 'master gland' of the endocrine system and located at the base of the brain, secretes various hormones that control other glands?

Correct Answer: B

Rationale: The pituitary gland is correctly known as the 'master gland' of the endocrine system. It is situated at the base of the brain and plays a crucial role in secreting a variety of hormones that regulate the functions of other endocrine glands in the body. These hormones control growth, metabolism, reproduction, and various other essential bodily functions. The other choices, thyroid gland, adrenal gland, and pancreas, are incorrect as they do not serve as the 'master gland' of the endocrine system nor are located at the base of the brain like the pituitary gland.

Question 3 of 5

How can you differentiate between a bacterial and viral infection based solely on symptoms?

Correct Answer: A

Rationale: It is impossible to differentiate between a bacterial and viral infection based solely on symptoms because many symptoms overlap between the two types of infections. Symptoms like fever, cough, and others can be present in both bacterial and viral infections. Additional diagnostic tests such as cultures or blood tests are often needed to determine the cause of the infection accurately. Relying only on symptoms can lead to misdiagnosis and inappropriate treatment. Choices B, C, and D are incorrect because they oversimplify the differentiation process and do not encompass the complexity of symptoms associated with bacterial and viral infections. While it is true that bacterial infections may respond to antibiotics and some differences in symptoms may be observed between bacterial and viral infections, these are not definitive indicators without proper diagnostic tests.

Question 4 of 5

What happens during a physical change in matter?

Correct Answer: C

Rationale: During a physical change in matter, the original substance undergoes a change in its physical state or appearance without any change in its chemical composition. This means that the original substance can be recovered by physical means, such as melting, freezing, boiling, or condensing. No new substance is formed (option A), the chemical composition remains the same (option B), and energy changes can occur but are not a defining characteristic of a physical change (option D). The ability to recover the original substance by physical means distinguishes physical changes from chemical changes.

Question 5 of 5

What is the external body covering, providing protection and contributing to temperature regulation, composed of?

Correct Answer: B

Rationale: The external body covering, which is the skin, is composed of epithelial tissue. Epithelial tissue serves as a protective barrier against pathogens, chemicals, and physical damage. It also helps regulate body temperature through processes like sweating. Choice A (Muscle tissue) is incorrect as muscles are responsible for movement and not the external body covering. Choice C (Bone marrow) is incorrect as it is a component of the skeletal system and not the external body covering. Choice D (Cartilage) is incorrect as cartilage is a type of connective tissue found in joints and the structure of some body parts, not the external body covering.
