1. Which of these is not an example of a lipid?

• A. Butter
• B. Wax
• C. Canola oil
• D. Honey

Correct answer: D

Rationale: Honey is not an example of a lipid because lipids are fat-related molecules that are insoluble in water, while honey is a natural sweet substance made by bees and primarily consists of sugars such as glucose and fructose. Butter, wax, and canola oil are examples of lipids as they are all composed of fat-related molecules that do not dissolve in water.

2. What organelle is responsible for packaging, processing, and shipping?

• A. Nucleus
• B. Golgi Apparatus
• C. Endoplasmic Reticulum
• D. Ribosomes

Correct answer: B

Rationale: The Golgi Apparatus is the correct answer. It is responsible for packaging, processing, and shipping proteins and lipids within the cell. The nucleus houses genetic material, the endoplasmic reticulum is involved in protein synthesis and lipid metabolism, and ribosomes are responsible for protein synthesis. Therefore, choices A, C, and D are not the correct answers for the functions of packaging, processing, and shipping.

3. What is the initial step in the metabolism of food to cellular energy?

• A. Citric Acid Cycle
• B. Glycolysis
• C. Electron Transport Chain
• D. Photosynthesis

Correct answer: B

Rationale: The correct answer is B: Glycolysis. Glycolysis is the initial step in the metabolism of food to cellular energy. During glycolysis, glucose is broken down into pyruvate, generating ATP and NADH. Choices A, C, and D are incorrect because the Citric Acid Cycle and Electron Transport Chain occur later in cellular respiration, while Photosynthesis is the process by which plants convert light energy into chemical energy.

4. Muscles are connected to bones by ______, and bones are connected to each other by ______.

• A. Muscles
• B. Tendons, ligaments
• C. Muscles
• D. Ligaments

Correct answer: B

Rationale: Muscles are connected to bones by tendons, which allow the muscle to exert force on the bone for movement. Bones are connected to each other by ligaments, which provide stability and support to the joints between bones. This relationship between muscles, tendons, bones, and ligaments is essential for proper movement and function of the musculoskeletal system. Choice A is incorrect because muscles are not directly connected to bones; tendons serve as the connection between muscles and bones. Choice D is incorrect because ligaments connect bones to each other, not muscles to bones.

5. A scientist needs 12 mL of a solution. They have a bottle with 12L in it. Do they have enough?

• A. Yes, they have exactly what they need
• B. Yes, they have more than what they need
• C. No, they do not have enough
• D. None of the above

Correct answer: B

Rationale: 1 liter has 1000 milliliters. To convert from milliliters to liters, the decimal point moves three places to the left. So, the bottle has 12000 mL of solution, which is a lot more than the required 12 mL. Therefore, the scientist has more than what they need. Choice A is incorrect as the bottle has more than the required amount. Choice C is incorrect as the bottle contains significantly more solution than needed. Choice D is incorrect as the scientist does have more than enough solution.
