English Grammar
1. Identify the subject in the following sentence: "The red car parked in the driveway."
- A. driveway
- B. red
- C. car
- D. the
Correct answer: C
Rationale: The subject is the noun or pronoun performing the action or being described in the sentence.
2. The outermost layer of your skin, responsible for waterproofing and providing a barrier against pathogens, is the:
- A. Stratum basale (Basal layer)
- B. Stratum corneum
- C. Stratum granulosum
- D. Stratum spinosum
Correct answer: B
Rationale: The correct answer is B: Stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells (corneocytes) that are continuously shed and replaced. This layer is responsible for waterproofing the skin and providing a barrier against pathogens, UV radiation, and other environmental factors. The stratum basale (A) is the deepest layer of the epidermis where new skin cells are produced. The stratum granulosum (C) is the layer of the epidermis where cells begin to flatten and keratinization begins. The stratum spinosum (D) is the layer above the stratum granulosum, where cells become interconnected by desmosomes. Therefore, the stratum corneum is specifically designed to fulfill the functions of waterproofing and protecting against pathogens.
3. Which hormone stimulates the release of calcium from bones and increases blood calcium levels?
- A. Parathyroid hormone (PTH)
- B. Calcitonin
- C. Growth hormone
- D. Testosterone
Correct answer: A
Rationale: The correct answer is A: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands and plays a crucial role in regulating calcium levels in the blood. When blood calcium levels are low, PTH is released to stimulate the release of calcium from bones, increase calcium absorption in the intestines, and reduce calcium loss in the kidneys. This process helps to maintain the necessary balance of calcium in the body. Calcitonin, on the other hand, works in opposition to PTH by decreasing blood calcium levels. Growth hormone primarily stimulates growth and development of tissues, while testosterone is a male sex hormone and does not directly impact calcium regulation.
4. Identify the bone with the greatest length in the human body.
- A. Femur (Thigh bone)
- B. Humerus (Upper arm bone)
- C. Tibia (Shin bone)
- D. Scapula (Shoulder blade)
Correct answer: A
Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.
5. Which sentence uses the colon correctly?
- A. I brought snacks: chips, salsa, and guacamole.
- B. The winner is: Sarah!
- C. He loves all things chocolate: cake, ice cream, and candy bars.
- D. Please bring the following items: pen, paper, and stapler.
Correct answer: A
Rationale: Colons are used to introduce a list or explanation that follows an independent clause. Options (a) and (c) use the colon correctly.
6. A scientist observes a new species of bird with uniquely shaped wings. They hypothesize that the wing shape allows for superior gliding ability. Which observation would most strongly support this hypothesis?
- A. The bird is found in mountainous regions.
- B. The bird has feathers with low friction.
- C. The bird can fly long distances without flapping.
- D. The bird's wing muscles are stronger than other birds.
Correct answer: C
Rationale: Direct observation of gliding ability directly tests the hypothesis about the wing shape's function. Other observations might be relevant but provide less direct evidence.
