1. Which chemical structure is represented by glycerol combined with two fatty acids?

• A. Compound lipids
• B. Monoglycerides
• C. Diglycerides
• D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. This study, which is an in-depth study of one boy, is a:

• A. case study
• B. longitudinal study
• C. cross-sectional study
• D. evaluative study

Correct answer: A

Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

3. A multivitamin supplement containing folic acid is recommended for all young women because of the number of unintentional pregnancies in women 15 to 24 years old.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: Both the statement and the reason are correct and related. A multivitamin with folic acid is recommended for young women due to the high incidence of unplanned pregnancies in this age group.

4. Which of the following actions are individuals with loss of smell NOT inclined to do?

• A. Use more spices in their food
• B. Eat less food
• C. Eat and drink more sweets
• D. Lose weight

Correct answer: D

Rationale: Individuals with a loss of smell are typically inclined to eat less because the enjoyment of food is diminished due to the lack of taste. However, they may compensate for this loss by consuming more sweets or using more spices. Therefore, they are less inclined to lose weight because of the increased consumption of sweets and spices, not because they eat less. Choice 'A' is incorrect because individuals with loss of smell often use more spices to enhance the taste of their food. Choice 'B' is incorrect as they may indeed eat less due to the diminished enjoyment of food. Choice 'C' is also incorrect as they tend to eat and drink more sweets to compensate for their loss of taste.

5. Each statement is true of water-soluble vitamins, except one. Which is it?

• A. Act as coenzymes
• B. Deficiencies develop rapidly
• C. Daily intake is necessary
• D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.
