TEAS Test 7 science quizlet
1. What is the main difference between white and brown adipose tissue?
- A. Location only
- B. Function and energy metabolism
- C. Color only
- D. Both white and brown have the same function
Correct answer: B
Rationale: The main difference between white and brown adipose tissue lies in their function and energy metabolism. White adipose tissue is primarily involved in energy storage, while brown adipose tissue is specialized for energy expenditure and thermogenesis. This functional disparity is the key dissimilarity between white and brown adipose tissue, rather than just their location or color. Choice A is incorrect because the difference is not only in location but also in function. Choice C is incorrect as color is not the defining factor in their distinction. Choice D is incorrect as white and brown adipose tissues serve different functions in the body.
2. What is the primary function of the small intestine?
- A. To absorb water
- B. To absorb nutrients
- C. To store waste
- D. To produce enzymes
Correct answer: B
Rationale: The correct answer is B: "To absorb nutrients." The small intestine's primary function is to absorb nutrients from digested food. It plays a crucial role in the digestion and absorption of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals, which are essential for the body's functions and energy production. Choice A, "To absorb water," is incorrect because the absorption of water primarily occurs in the large intestine. Choice C, "To store waste," is incorrect as waste is stored in the large intestine before elimination. Choice D, "To produce enzymes," is incorrect because while the small intestine does receive enzymes from other organs to aid in digestion, its primary role is not enzyme production.
3. Which structure in the female reproductive system is responsible for producing eggs (ova)?
- A. Fallopian tubes
- B. Ovaries
- C. Uterus
- D. Vagina
Correct answer: B
Rationale: The correct answer is the ovaries. Ovaries are the primary reproductive organs in females responsible for producing eggs (ova) through a process known as oogenesis. Ova are released from the ovaries during ovulation and can be fertilized by sperm in the fallopian tubes. The uterus is where a fertilized egg implants and develops into a fetus, while the vagina serves as the birth canal and a site for sexual intercourse. Fallopian tubes are responsible for transporting eggs from the ovaries to the uterus and are the site where fertilization typically occurs. Therefore, while important for the reproductive process, the fallopian tubes do not produce eggs.
4. What is the primary function of the spleen, an organ associated with the lymphatic system?
- A. Regulating blood sugar levels
- B. Filtering blood and destroying old red blood cells
- C. Producing digestive enzymes
- D. Secreting hormones
Correct answer: B
Rationale: The spleen is primarily responsible for filtering blood and destroying old or damaged red blood cells. It also aids in storing blood and producing specific types of white blood cells, contributing to maintaining blood quality and immune system function. Choices A, C, and D are incorrect because the spleen is not involved in regulating blood sugar levels, producing digestive enzymes, or secreting hormones. These functions are carried out by other organs in the body.
5. Which term is used interchangeably with negative variation?
- A. Non-correlation
- B. Direct correlation
- C. Inverse correlation
- D. Positive correlation
Correct answer: C
Rationale: The correct answer is C: Inverse correlation. Negative variation is synonymous with inverse correlation, indicating that as one variable increases, the other decreases. This relationship is the opposite of positive correlation, where both variables increase or decrease together. Non-correlation and direct correlation do not convey the concept of negative variation and are not interchangeable terms in this context. Non-correlation refers to variables that are not related or associated, while direct correlation indicates that as one variable increases, the other also increases. Positive correlation describes a relationship where both variables increase together, which is the opposite of negative variation.
