1. Which of the following is another name for a sweat gland?

Correct answer: C

Rationale: The correct answer is C: Sudoriferous. Sudoriferous glands are commonly known as sweat glands and are responsible for producing perspiration to regulate body temperature. Ceruminous glands produce earwax, sebaceous glands produce sebum (oil), and 'Integumentary' refers to the integumentary system, which includes the skin, hair, and nails. Choice A, Ceruminous glands, are responsible for producing earwax, not sweat. Choice B, Sebaceous glands, produce sebum (oil) to lubricate the skin and hair. Choice D, Integumentary, refers to the integumentary system, not a specific type of gland.

2. What do hair follicles house in the skin?

Correct answer: C

Rationale: Hair follicles are structures in the skin that contain the hair shaft (the visible part of the hair) and the hair root (the part of the hair beneath the skin). The hair shaft is the portion of the hair that is visible above the skin, while the hair root is the part that extends below the surface into the follicle. Therefore, the correct answer is that hair follicles house the hair shafts and hair roots. Choices A, B, and D are incorrect because blood vessels are not housed within hair follicles, nerve endings are present but not housed within hair follicles, and sebaceous glands are often attached to hair follicles but not housed within them.

3. What does 'monophyletic' mean in the context of classification?

Correct answer: D

Rationale: In the context of classification, 'monophyletic' refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term 'monophyletic' in the context of classification. Choices A, B, and C are incorrect. Choice A is incorrect because 'monophyletic' does not refer to a group with a single representative organism but rather a group descended from a common ancestor. Choice B is incorrect as a monophyletic group consists of related, not diverse and unrelated, members. Choice C is incorrect as a monophyletic group includes descendants from a common ancestor, not just organisms with similar functions but different origins.

4. Which deadly disease was eliminated through an intensive vaccination program?

Correct answer: B

Rationale: Smallpox was eradicated globally through an intensive vaccination program. The World Health Organization (WHO) led a successful global campaign to vaccinate people against smallpox, ultimately leading to its eradication in 1980. AIDS, diabetes type 1, and rheumatoid arthritis are serious conditions, but they were not eliminated through vaccination programs like smallpox. Therefore, the correct answer is B, Smallpox. AIDS is caused by the human immunodeficiency virus (HIV) and remains a significant global health issue. Diabetes type 1 is an autoimmune condition where the body attacks insulin-producing cells, leading to high blood sugar levels. Rheumatoid arthritis is an autoimmune condition that primarily affects the joints, causing inflammation and pain.

5. Balance the following redox reaction in acidic solution: I⁻ (aq) + Cr₂O₇²⁻ (aq) -> I₂ (aq) + Cr³⁺ (aq). Identify the oxidizing agent and reducing agent.

Correct answer: B

Rationale: In the given redox reaction, I⁻ is gaining electrons to form I₂, which means I⁻ is being reduced (undergoing reduction). On the other hand, Cr₂O₇²⁻ is losing electrons to form Cr³⁺, indicating that Cr₂O₇²⁻ is being oxidized (undergoing oxidation). Therefore, I⁻ is the reducing agent and Cr₂O₇²⁻ is the oxidizing agent. Choice A is incorrect because I⁻ is being reduced, not oxidized. Choice C is incorrect as both species cannot be oxidized in the same reaction. Choice D is incorrect as both species cannot be reduced in the same reaction.
