1. Which of the following processes does not help maintain the life of an individual organism?

• A. Responsiveness
• B. Movement
• C. Reproduction
• D. Respiration

Correct answer: C

Rationale: Reproduction is the correct answer because it is not essential for maintaining the life of an individual organism. While reproduction is crucial for the continuation of a species, it is not directly related to the survival or maintenance of an individual organism. Responsiveness allows an organism to react to stimuli, movement helps in obtaining resources and avoiding danger, and respiration provides the necessary energy for life processes. Therefore, reproduction is the process that does not directly contribute to maintaining the life of an individual organism.

2. Which of the following lists best illustrates the idea of increasing levels of complexity?

• A. Cells, tissues, organelles, organs, organ systems
• B. Tissues, cells, organs, organelles, organ systems
• C. Organs, organelles, organ systems, cells, tissues
• D. Organelles, cells, tissues, organs, organ systems

Correct answer: D

Rationale: The correct answer is D: Organelles, cells, tissues, organs, organ systems. This list correctly depicts the increasing levels of complexity in biological organization. It starts with organelles, which are subunits within cells, followed by cells, then tissues (groups of cells working together), organs (comprised of different tissues), and finally organ systems (multiple organs working together). Choices A, B, and C are incorrect as they do not follow the logical progression of complexity from smaller units to larger, more complex structures.

3. Most of the terminology to name and describe body parts and their functions comes from

• A. Latin and Greek.
• B. English and Italian.
• C. Pictures drawn on the cave walls of our ancestors.
• D. The language of hunter-gatherers.

Correct answer: A

Rationale: The correct answer is Latin and Greek. Medical terminology is largely derived from Latin and Greek roots. These languages have been foundational in the development of medical terminology due to the precision and descriptive nature of their vocabulary. Choice B, English and Italian, is incorrect because while some medical terms may have originated from these languages, the majority come from Latin and Greek. Choices C and D, pictures drawn on the cave walls of our ancestors and the language of hunter-gatherers, are both incorrect as they do not align with the historical origins of medical terminology.

4. Living organisms use oxygen to __________________.

• A. reduce heat production
• B. accept electrons for cellular metabolism
• C. release energy stored in the molecules of food
• D. remove metabolic wastes

Correct answer: C

Rationale: The correct answer is C. Living organisms use oxygen to release energy stored in the molecules of food through a process called cellular respiration. This process involves breaking down glucose molecules in the presence of oxygen to produce energy in the form of ATP. Choice A is incorrect because oxygen does not directly reduce heat production in organisms. Choice B is incorrect because oxygen is involved in accepting electrons rather than donating them in cellular metabolism. Choice D is incorrect because the removal of metabolic wastes is not the primary role of oxygen in living organisms.

5. Which of the following characteristics of life and their descriptions are correct?

• A. Responsiveness - detecting and responding to changes in the environment
• B. Assimilation - incorporating absorbed substances into the body
• C. Respiration - obtaining energy from food molecules through oxygen
• D. Circulation - the movement of substances in body fluids

Correct answer: D

Rationale: The correct answer is D: Circulation - the movement of substances in body fluids. Circulation refers to the movement of substances like nutrients, gases, and wastes in body fluids to and from cells. Choice A is incorrect because responsiveness is about detecting and responding to changes in the environment, not obtaining and using oxygen. Choice B is incorrect because assimilation is the process of incorporating absorbed substances into the body, not changing them into chemically different forms. Choice C is incorrect because respiration is the process of obtaining energy from food molecules through oxygen, not the obtaining and using oxygen itself.
