1. 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.

2. An obstetrician tells a 42-year-old patient that she can have a healthy baby, but that she is of 'advanced maternal age.' The patient is so upset that she fails to listen to the rest of the doctor's advice, goes home in a huff, and immediately dyes her hair.

A. the age of the sperm.
B. the age of her eggs.
C. her risk of developing diabetes.
D. her cholesterol level, not her appearance.

Correct answer: B

Rationale: The correct answer is 'the age of her eggs.' As women age, the quality of their eggs decreases, leading to a higher risk of chromosomal abnormalities and infertility. This decline in egg quality is why advanced maternal age is associated with a higher risk of certain pregnancy complications. Choices A, C, and D are incorrect because the primary concern in this context is related to the age-related changes in a woman's eggs, not sperm, diabetes risk, or cholesterol levels.

3. Which of the following is not true of organelles?

A. They carry out specific activities.
B. They are only present in human cells.
C. They are composed of aggregates of large molecules.
D. They are found in many types of cells.

Correct answer: B

Rationale: Organelles are not exclusive to human cells but are present in various types of cells across different organisms. Option B is incorrect as it suggests that organelles are only found in human cells, which is false. Choices A, C, and D are correct statements about organelles. Organelles indeed carry out specific activities, are made up of aggregates of large molecules, and can be found in many types of cells.

4. 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.

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.
