1. Which type of nutrients require minimal digestion before absorption?

Correct answer: D

Rationale: A) Carbohydrates: Carbohydrates require digestion by enzymes in the mouth, stomach, and small intestine before they can be broken down into simple sugars for absorption. B) Proteins: Proteins need to be broken down into amino acids by stomach acid and digestive enzymes in the stomach and small intestine before they can be absorbed. C) Fats: Fats require bile from the gallbladder to emulsify them into smaller droplets for enzymes to break them down into fatty acids and glycerol for absorption. D) Vitamins: Vitamins are organic compounds that are already in a form that can be readily absorbed by the body without extensive digestion. They are absorbed directly into the bloodstream from the small intestine and do not require significant breakdown before absorption.

2. Which of the following hormones is produced by the adrenal medulla and prepares the body for a stressful situation?

Correct answer: C

Rationale: The correct answer is C: Epinephrine (adrenaline). Epinephrine is produced by the adrenal medulla and is responsible for preparing the body for a stressful situation. It increases heart rate, dilates airways, and mobilizes energy stores to help the body respond to a fight-or-flight scenario. Testosterone (Choice A) is a sex hormone produced by the testes in males and in smaller amounts by the ovaries in females, not by the adrenal medulla. Cortisol (Choice B) is a stress hormone produced by the adrenal cortex, not the adrenal medulla. Growth hormone (Choice D) is produced by the pituitary gland and is involved in growth, metabolism, and various bodily functions, not by the adrenal medulla.

3. Which type of blood cell is responsible for carrying oxygen?

Correct answer: B

Rationale: The correct answer is B: Red blood cell. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues. They contain hemoglobin, a protein that binds to oxygen and transports it throughout the body. White blood cells (Choice A) are part of the immune system and help fight infections, not involved in carrying oxygen. Platelets (Choice C) are responsible for blood clotting, not oxygen transport. Plasma (Choice D) is the liquid component of blood that carries various substances like nutrients and waste products, but it does not directly carry oxygen.

4. In the statement above, several items are italicized, while only one is placed in quotation marks. According to the rules of punctuation, the following should be placed in quotation marks: article titles, book chapters, short stories, and episodes of television shows. Considering the list of works that Angela read, into which category does 'The Cask of Amontillado' most likely fit?

Correct answer: C

Rationale: 'The Cask of Amontillado' is a short story written by Edgar Allan Poe. Short stories are considered literary works that should be placed in quotation marks according to the rules of punctuation. Therefore, 'The Cask of Amontillado' would fall under the category of works that should be placed in quotation marks.

5. Sally wants to buy a used truck for her delivery business. Truck A is priced at $450 and gets 25 miles per gallon. Truck B costs $650 and gets 35 miles per gallon. If gasoline costs $4 per gallon, how many miles must Sally drive to make truck B the better buy?

Correct answer: D

Rationale: To determine the breakeven point where Truck B becomes the better buy, we need to compare the total costs for both trucks. For Truck A: Total cost = $450 + (miles / 25) * $4. For Truck B: Total cost = $650 + (miles / 35) * $4. To find the point where Truck B is the better buy, set the two total cost equations equal to each other and solve for miles. By solving this equation, we find that Sally must drive 4375 miles for Truck B to be the better buy. Choice A (500) is too low, Choice B (7500) is too high, and Choice C (1750) does not represent the breakeven point where Truck B becomes more cost-effective.
