1. Which cell organelle functions to transport materials from the endoplasmic reticulum throughout the cell?

• A. Ribosome
• B. Golgi apparatus
• C. Lysosome
• D. Vacuole

Correct answer: B

Rationale: The Golgi apparatus is the correct answer because it functions to transport materials from the endoplasmic reticulum throughout the cell. Ribosomes are responsible for protein synthesis, not transportation of materials. Lysosomes contain enzymes for digestion and waste removal, not for transporting materials. Vacuoles are primarily involved in storage, waste disposal, and maintaining turgor pressure, not in transporting materials from the endoplasmic reticulum.

2. Which animal has an open transport system?

• A. Grasshopper
• B. Earthworm
• C. Dolphin
• D. Chicken

Correct answer: B

Rationale: The correct answer is B: Earthworm. Earthworms have an open circulatory system, meaning their blood and interstitial fluid are not enclosed in blood vessels. Instead, the blood flows freely within the body cavity, allowing for direct exchange of nutrients and waste products with surrounding tissues. This lack of a closed transport system is a characteristic feature of earthworms. Choices A, C, and D are incorrect because grasshoppers, dolphins, and chickens have closed circulatory systems where the blood is enclosed within blood vessels, unlike earthworms.

3. Which of the following is not true about antibiotics?

• A. They can interfere with the bacteria's ability to survive
• B. They can affect how bacteria multiply
• C. They can cause more bacteria to grow
• D. They only work on bacteria

Correct answer: C

Rationale: The correct answer is C. Antibiotics do not cause more bacteria to grow. They work by interfering with the bacteria's ability to survive, affecting how they multiply, or killing the bacteria cells. Antibiotics specifically target bacteria, so they do not promote the growth of more bacteria. Choices A, B, and D are true statements about antibiotics as they accurately describe how antibiotics work and their specific action on bacteria.

4. Athletes are often concerned with the question of what they need in their diets to increase muscle mass and strength. What biologic molecule would you recommend that would accomplish this?

• A. carbohydrates
• B. proteins
• C. lipids
• D. nucleic acids

Correct answer: B

Rationale: Proteins are essential for building and repairing muscle tissue. They contain amino acids, which are the building blocks of muscles. Athletes looking to increase muscle mass and strength should focus on consuming adequate amounts of high-quality proteins in their diets. Carbohydrates provide energy for workouts, lipids are important for overall health but do not directly contribute to muscle building, and nucleic acids are involved in genetic activities rather than muscle growth.

5. What type of cell is an animal cell?

• A. Prokaryotic
• B. Eukaryotic
• C. Plant Cell
• D. Bacterial Cell

Correct answer: B

Rationale: The correct answer is B, eukaryotic. Animal cells are classified as eukaryotic cells because they contain membrane-bound organelles such as the nucleus, mitochondria, and endoplasmic reticulum. Choice A, prokaryotic, is incorrect as prokaryotic cells lack membrane-bound organelles. Choice C, Plant Cell, is incorrect as the question specifically asks about animal cells. Choice D, Bacterial Cell, is incorrect as bacteria are prokaryotic cells.
