1. Which of the following is NOT a way that theme is conveyed in nonfiction text?

• A. Through events
• B. Through word choice
• C. Through imagery
• D. Through meter

Correct answer: D

Rationale: Meter is a poetic device used in poetry to establish rhythm and rhyme, which is not typically found in nonfiction texts. In nonfiction, theme is often conveyed through events, word choice, and imagery. Events help illustrate the main ideas and messages, word choice influences the tone and mood of the text, and imagery enhances the descriptive elements. Therefore, meter, being more closely related to poetry, is not a common way to convey theme in nonfiction.

2. What is the monomer for nucleic acids?

• A. Nucleotide
• B. Amino acid
• C. Phosphate group
• D. Ribosome

Correct answer: A

Rationale: The correct answer is A: Nucleotide. Nucleotides are indeed the monomers that make up nucleic acids like DNA and RNA. They consist of a sugar molecule, a phosphate group, and a nitrogenous base. Amino acids are the monomers of proteins, not nucleic acids. While the phosphate group is a component of nucleotides, it is not the sole monomer. Ribosome is a cellular organelle involved in protein synthesis and is not a monomer for nucleic acids.

3. What do hair follicles house in the skin?

• A. Blood vessels (Blood vessels are not housed within hair follicles)
• B. Nerve endings (Nerve endings are present but not housed within hair follicles)
• C. Hair shafts and hair roots
• D. Sebaceous glands (These glands are often attached to hair follicles)

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.

4. What is the process by which a population gradually loses genetic variation?

• A. Founder effect
• B. Bottleneck effect
• C. Gene flow
• D. Speciation

Correct answer: B

Rationale: A) Founder effect: This occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not necessarily result in a gradual loss of genetic variation in an existing population. B) Bottleneck effect: This process occurs when a population is drastically reduced in size, leading to a significant loss of genetic variation due to the limited number of individuals contributing to the gene pool. The reduced genetic diversity can have long-term effects on the population's ability to adapt to environmental changes. C) Gene flow: This refers to the movement of genes between populations, which can introduce new genetic variation and prevent populations from diverging. Gene flow does not lead to a gradual loss of genetic variation within a population. D) Speciation: This is the process by which new species evolve from existing species, often involving the accumulation of genetic differences that l

5. What is the name of the condition characterized by inflammation of the small intestine?

• A. Appendicitis
• B. Celiac disease
• C. Gastritis
• D. Crohn's disease

Correct answer: D

Rationale: A) Appendicitis is inflammation of the appendix, not the small intestine. B) Celiac disease is an autoimmune disorder triggered by gluten consumption that damages the small intestine, but it is not characterized by inflammation alone. C) Gastritis is inflammation of the stomach lining, not the small intestine. D) Crohn's disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract, but it commonly involves the small intestine. Symptoms of Crohn's disease include abdominal pain, diarrhea, weight loss, and fatigue.
