Temperature is a form of energy, whereas heat is a measurement of the intensity of the temperature.
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: A
Rationale: The statement is true. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy from a hotter object to a colder one. Heat is not a measurement of the intensity of temperature, but rather the energy transfer due to a temperature difference. Therefore, the correct answer is True. Choice B (False) is incorrect as the statement is true based on the definitions of temperature and heat.

The ability of an organism to sense and react to changes in its body illustrates
- A. circulation.
- B. respiration.
- C. responsiveness.
- D. absorption
Correct Answer: C.
Rationale: The correct answer is 'responsiveness.' Responsiveness refers to the ability of an organism to detect and respond to stimuli in its environment. In this context, it specifically relates to an organism's ability to sense and react to changes within its body. Choices A, B, and D are incorrect. Circulation refers to the movement of fluids within an organism, respiration is the process of exchanging gases, and absorption is the uptake of substances by cells or tissues.
Which of the following organs is in the abdominopelvic cavity?
- A. The heart
- B. The trachea
- C. The thymus
- D. The liver
Correct Answer: D
Rationale: The correct answer is the liver. The liver is located in the abdominopelvic cavity, which is the space between the diaphragm and the pelvic floor. The heart, trachea, and thymus are not located in the abdominopelvic cavity. The heart is situated in the thoracic cavity, the trachea is in the neck region, and the thymus is located in the upper chest. Understanding the anatomical locations of organs is crucial for medical professionals to accurately diagnose and treat patients.
Do chromosomes get longer as a cell ages?
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: B
Rationale: Chromosomes do not get longer as a cell ages. In fact, chromosomes condense and become more compact during cell division to ensure proper segregation. Choice A is incorrect because chromosomes do not elongate with age. Choice C is not the correct answer as there is scientific evidence to support that chromosomes do not lengthen over time. Choice D is not the right option as the correct answer is 'False' in this case.
Does the digestive system filter wastes from the blood?
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: B
Rationale: The correct answer is False. The digestive system is responsible for breaking down food and absorbing nutrients, not filtering wastes from the blood. The excretory system, particularly the kidneys, filters wastes from the blood to form urine. Choices A, C, and D are incorrect because the digestive system's primary function is not waste filtration but rather digestion and absorption of nutrients.
Blood cells are produced in the organs of the _______ system.
- A. endocrine
- B. skeletal
- C. superior to
- D. inferior to
Correct Answer: C
Rationale: Blood cells are produced in the organs of the hematopoietic system. The correct answer is 'superior to' as this refers to the location of the organs responsible for blood cell production, typically bone marrow found in bones such as the vertebrae, ribs, and skull. 'Endocrine' (Choice A) refers to a different system responsible for hormone production. 'Skeletal' (Choice B) relates to bones but not specifically to the production of blood cells. Choices C and D, 'superior to' and 'inferior to,' do not make sense in the context of blood cell production and are incorrect.
