1. Dogs are part of a larger animal group, the Carnivora. What classification is this?

• A. Kingdom
• B. Class
• C. Order
• D. Genus

Correct answer: C

Rationale: The classification 'Carnivora' refers to an order in the taxonomic hierarchy. In the Linnaean classification system, the order comes below the class but above the family level. Therefore, Carnivora is a higher classification that includes dog species as well as other carnivorous mammals like cats, bears, and weasels. Option A (Kingdom) is too broad and refers to the highest taxonomic rank. Option B (Class) is a lower taxonomic rank than order. Option D (Genus) is a much more specific rank that comes below the family level in the Linnaean hierarchy.

2. Which organism reproduces via spore formation?

• A. Shelf fungus
• B. Lemon tree
• C. Smallmouth bass
• D. Staphylococcus

Correct answer: A

Rationale: The correct answer is A, Shelf fungus. Shelf fungus reproduces via spore formation. Spores are tiny, reproductive cells that are released into the environment to be carried by air or water, allowing the fungus to spread and reproduce. The other choices are incorrect because Lemon tree reproduces via seeds, Smallmouth bass reproduce sexually through the fertilization of eggs by sperm, and Staphylococcus bacteria reproduce by binary fission, dividing into two identical daughter cells.

3. 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.

4. How many pairs of chromosomes do all humans have?

• A. 24 pairs
• B. 23 pairs
• C. 22 pairs
• D. 20 pairs

Correct answer: B

Rationale: All humans have 23 pairs of chromosomes, totaling 46 chromosomes. Choice A is incorrect because humans do not have 24 pairs. Choice C is incorrect as humans have 23 pairs, not 22 pairs. Choice D is incorrect as humans have 23 pairs of chromosomes, not 20 pairs.

5. 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.
