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.

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.
Simple squamous epithelium is an example of a(n)
- A. organ system.
- B. organ.
- C. tissue.
- D. molecule.
Correct Answer: C
Rationale: Simple squamous epithelium is a type of tissue, not an organ system, organ, or molecule. Tissues are groups of cells that work together to perform a specific function. In this case, simple squamous epithelium is a thin, single layer of flattened cells that line surfaces involved in passive diffusion, such as the alveoli in the lungs or blood vessels. Therefore, the correct answer is 'tissue.' Choices A, B, and D are incorrect as they do not accurately categorize simple squamous epithelium as a tissue.
Is oxygen the primary raw material for new living material?
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: B
Rationale: While oxygen is essential for many living organisms, it is not the primary raw material for new living material. The primary raw materials for new living material are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, collectively known as CHNOPS elements. These elements are the building blocks of biological molecules and are essential for life. Therefore, the correct answer is False. Choices C and D are incorrect because the primary raw materials for new living material are well-established in biology.
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.
Reproduction is the change in body characteristics over time.
- A. TRUE
- B. FALSE
- C. Not Sure
- D. None of the above
Correct Answer: B
Rationale: Reproduction is the process by which living organisms produce offspring of the same kind. It is not related to changes in body characteristics over time. Therefore, the statement is false. Choices C and D are also incorrect as they do not align with the definition of reproduction.
