1. Which of the following is an incomplete sentence?
- A. Watch out.
- B. In the rose garden out back.
- C. I guess that's true.
- D. It would take about three weeks.
Correct answer: B
Rationale: The correct answer is B: 'In the rose garden out back.' This is an incomplete sentence because it lacks a subject and a verb. A complete sentence requires both a subject (who or what the sentence is about) and a verb (action or state of being). Choices A, C, and D are complete sentences as they have the necessary components to form a grammatically correct sentence. 'Watch out' has an implied subject (you) and verb (watch), 'I guess that's true' has the subject 'I' and the verb 'guess', and 'It would take about three weeks' has the subject 'It' and the verb phrase 'would take.'
2. What potential consequences can chromosomal nondisjunction have on offspring?
- A. Down syndrome, caused by an extra copy of chromosome 21.
- B. Turner syndrome, characterized by the absence of one X chromosome in females.
- C. Klinefelter syndrome, featuring one or more extra X chromosomes in males.
- D. All of the above.
Correct answer: D
Rationale: - Chromosomal nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to an abnormal number of chromosomes in the resulting cells. - Down syndrome is caused by an extra copy of chromosome 21, resulting from nondisjunction during meiosis. Individuals with Down syndrome have three copies of chromosome 21 instead of the usual two. - Turner syndrome is characterized by the absence of one X chromosome in females, leading to a variety of physical and developmental features. - Klinefelter syndrome features one or more extra X chromosomes in males, typically resulting in infertility and other physical characteristics. Therefore, chromosomal nondisjunction can lead to various genetic disorders such as Down syndrome, Turner syndrome, and Klinefelter syndrome, making option D the correct answer.
3. Which epithelial tissue type is the outermost layer of your skin an example of?
- A. Simple cuboidal
- B. Stratified squamous
- C. Simple columnar
- D. Stratified columnar
Correct answer: B
Rationale: The outermost layer of the skin, known as the epidermis, is composed of stratified squamous epithelial tissue. This type of tissue is well-suited for protection against mechanical stress and dehydration, making it ideal for the skin's barrier function. Simple cuboidal (Choice A) epithelial tissue is found in areas where secretion and absorption occur, such as kidney tubules. Simple columnar (Choice C) epithelial tissue lines the digestive tract, providing a large surface area for absorption. Stratified columnar (Choice D) epithelial tissue is less common and is found in limited regions like parts of the male urethra and ducts of some glands, but not in the outermost layer of the skin.
4. On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30 cm². What is the actual area of the room?
- A. 30,000 cm²
- B. 300 m²
- C. 3,000 m²
- D. 30 m²
Correct answer: D
Rationale: On a 1:100 scale drawing, each centimeter represents one meter. The area of the room in the scale drawing is 30 cm², which means the actual area is 30 m². Choice A (30,000 cm²) is incorrect as it doesn't account for the scale conversion. Choice B (300 m²) is incorrect because it multiplies the scale area directly by 10,000, which is not the correct conversion. Choice C (3,000 m²) is also incorrect as it applies the scale factor incorrectly.
5. What does 'mm' stand for in the metric system?
- A. millimeter
- B. megabyte
- C. millipede
- D. metered
Correct answer: A
Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.
