1. Without enough calcium, both males and females are at risk of osteoporosis.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: A
Rationale: The statement is true. Both males and females are at risk of developing osteoporosis if they do not consume enough calcium. Calcium is essential for maintaining strong bones, and inadequate intake can lead to bone density loss and increase the risk of osteoporosis. Therefore, it is crucial for individuals of all genders to ensure they have an adequate calcium intake to support bone health. Choice B is incorrect because osteoporosis is a condition that can affect both males and females.
2. Which biomolecule is responsible for the storage and transfer of genetic information?
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Nucleic acids
Correct answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
3. In which condition is underconsumption of fat not a concern?
- A. Malabsorption syndromes
- B. Cystic fibrosis
- C. AIDS
- D. Hypertension
Correct answer: D
Rationale: The correct answer is D, Hypertension. Hypertension is not typically associated with underconsumption of fat; instead, it is more related to the consumption of excess fat, especially saturated and trans fats, which can contribute to increased blood pressure. Malabsorption syndromes, cystic fibrosis, and AIDS are conditions where underconsumption of fat can be a concern due to various reasons such as malabsorption issues, pancreatic insufficiency, or increased energy needs.
4. To raise HDL levels, what is Mrs. Smith advised to do?
- A. quit smoking
- B. increase dietary sodium
- C. take iron supplements
- D. avoid dairy products
Correct answer: A
Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.
5. Cancers that arise from epithelial tissues are known as:
- A. Leukemias
- B. Myelomas
- C. Carcinomas
- D. Sarcomas
Correct answer: C
Rationale: The correct answer is C: Carcinomas. Carcinomas are cancers that originate from epithelial tissues, which are the tissues lining the surfaces of organs and structures in the body. Leukemias (choice A) are cancers of the blood-forming cells, not epithelial tissues. Myelomas (choice B) are cancers that develop in plasma cells in the bone marrow, not epithelial tissues. Sarcomas (choice D) are cancers that arise from connective tissues like bone, cartilage, or muscle, not epithelial tissues. Therefore, choices A, B, and D are incorrect in the context of cancers originating from epithelial tissues.
