1. What is the perimeter of a rectangle with a length of 7 cm and a width of 3 cm?

• A. 21 cm
• B. 10 cm
• C. 14 cm
• D. 20 cm

Correct answer: D

Rationale: To find the perimeter of a rectangle, you add the lengths of all its sides. In this case, the formula for the perimeter of a rectangle is 2*(length + width). Substituting the given values, we get: 2*(7 cm + 3 cm) = 2*(10 cm) = 20 cm. Therefore, the correct answer is 20 cm. Choice A (21 cm) is incorrect because it is the sum of the individual sides rather than the perimeter. Choice B (10 cm) is incorrect because it only represents one side of the rectangle. Choice C (14 cm) is incorrect as it is not the total perimeter of the rectangle.

2. Two mice are both heterozygous for two traits: white fur (Ww) and short fur (Ss). Their offspring are most likely to have which of the following genotypes for these traits?

• A. wwss
• B. WWSS
• C. WwSs
• D. WWSs

Correct answer: C

Rationale: When two mice that are heterozygous for white fur (Ww) and short fur (Ss) mate, they can produce offspring with different combinations of the two traits. The Punnett square for this cross shows that the most likely genotype for the offspring is WwSs. In this case, each offspring receives one allele for white fur (W) and one for short fur (S) from each parent, resulting in a heterozygous genotype for both traits. Choice A (wwss) is incorrect as it represents a homozygous recessive genotype for both traits. Choice B (WWSS) is also incorrect as it represents a homozygous dominant genotype for both traits. Choice D (WWSs) is incorrect as it represents a genotype where one trait is homozygous dominant (W) and the other is heterozygous (S), which is not the most likely outcome based on the given parental genotypes.

3. Which of the following demonstrates correct punctuation?

• A. Graham still needs the following items for his class: a sable brush, soft pastels, a sketchbook, and an easel.
• B. Graham still needs the following items for his class, a sable brush, soft pastels, a sketchbook, and an easel.
• C. Graham still needs the following items for his class: a sable brush; soft pastels; a sketchbook; and an easel.
• D. Graham still needs the following items for his class – a sable brush; soft pastels; a sketchbook; and an easel.

Correct answer: A

Rationale: Choice A demonstrates correct punctuation. The sentence uses a colon to introduce a list, which is the most appropriate punctuation in this context. A colon is typically used to signal that a list or explanation follows, making it the suitable choice here. Choices B, C, and D either use a comma, semi-colon, or dash incorrectly to introduce the list, deviating from the standard punctuation rule for listing items. Therefore, they are incorrect in the context of this sentence.

4. Which option best exemplifies an author's use of alliteration and personification?

• A. Her mood hung about her like a weary cape, very dull from wear.
• B. It shuddered, swayed, shook, and screamed its way into dust under hot flames.
• C. The house was a starch sentry, warning visitors away.
• D. At its shoreline, visitors swore they heard the siren call of the cliffs above.

Correct answer: B

Rationale: Choice B best exemplifies an author's use of alliteration and personification. The sentence 'It shuddered, swayed, shook, and screamed its way into dust under hot flames' personifies an inanimate object (it) by attributing human actions to it, combining alliteration with the repeated 's' sounds. Choices A, C, and D do not contain both alliteration and personification. Choice A mainly focuses on simile and lacks alliteration. Choice C features personification but lacks alliteration. Choice D includes personification but lacks alliteration as well.

5. Osteoporosis is a condition that leads to weakened bones and an increased risk of fractures. Which hormone plays a key role in bone health and is often affected in osteoporosis?

• A. Estrogen
• B. Testosterone
• C. Thyroid hormone
• D. Insulin

Correct answer: A

Rationale: Estrogen plays a crucial role in maintaining bone health by inhibiting bone resorption and promoting bone formation. In postmenopausal women, estrogen levels decrease, leading to an increased risk of osteoporosis due to accelerated bone loss. This hormonal imbalance contributes to weakened bones and an increased risk of fractures in individuals with osteoporosis. Testosterone and thyroid hormone do play roles in bone health, but estrogen has a more significant impact. Testosterone is more commonly associated with muscle mass and strength, while thyroid hormone regulates metabolism. Insulin is not directly involved in bone health and is not typically affected in osteoporosis.
