English Grammar
1. Identify the predicate in the following sentence: "The children built a sandcastle on the beach."
- A. on the beach
- B. built a sandcastle
- C. children
- D. the
Correct answer: B
Rationale: The predicate is the verb and any words following it that describe the action or state of being of the subject.
2. Which of the following is NOT a recognized mode of natural selection?
- A. Directional selection (favoring one extreme trait value on a spectrum)
- B. Disruptive selection (favoring both extreme trait values on a spectrum)
- C. Stabilizing selection (favoring the average trait value on a spectrum)
- D. Sexual selection (selection based on mate choice that influences reproductive success)
Correct answer: D
Rationale: Rationale: A) Directional selection is a recognized mode of natural selection where one extreme trait value on a spectrum is favored over others. This can lead to a shift in the average trait value over time. B) Disruptive selection is a recognized mode of natural selection where both extreme trait values on a spectrum are favored over the average trait value. This can lead to the population splitting into two distinct groups. C) Stabilizing selection is a recognized mode of natural selection where the average trait value on a spectrum is favored over extreme values. This can lead to a reduction in genetic diversity within a population. D) Sexual selection is not a mode of natural selection in the traditional sense, as it involves mate choice and competition for mates rather than direct selection pressure on traits that affect survival and reproduction in the environment. Sexual selection can lead to the evolution of traits that enhance an individual's ability to attract
3. What property of a substance refers to its ability to be drawn into thin wires without breaking?
- A. Malleability
- B. Viscosity
- C. Ductility
- D. Conductivity
Correct answer: c
Rationale: Ductility is the property that describes a substance's ability to be drawn into thin wires without breaking.
4. A patient's oxygen flow rate is set at 4 liters per minute. How many cubic centimeters of oxygen are delivered per minute?
- A. 400 cubic centimeters
- B. 4,000 cubic centimeters
- C. 40,000 cubic centimeters
- D. 400,000 cubic centimeters
Correct answer: B
Rationale: Remember 1 liter is equal to 1000 cubic centimeters. Multiply the flow rate in liters per minute by the conversion factor: 4 liters/minute * 1000 cm³/liter = 4,000 cubic centimeters/minute.
5. Which element has the lowest electronegativity value?
- A. Oxygen
- B. Fluorine
- C. Helium
- D. Chlorine
Correct answer: C
Rationale: Electronegativity is the tendency of an atom to attract electrons towards itself in a bond. Noble gases like helium have very low electronegativity because their outer electron shell is already full and stable.
6. Which cartilage type allows for smooth movement at joints and absorbs shock?
- A. Hyaline cartilage
- B. Fibrocartilage
- C. Elastic cartilage
- D. None of the above
Correct answer: A
Rationale: The correct answer is A: Hyaline cartilage. Hyaline cartilage is the most abundant type of cartilage in the body and is found in the joints, providing a smooth surface for movement. It also acts as a shock absorber, cushioning the joints during activities. Fibrocartilage is found in intervertebral discs and provides strength and support, but it is not as effective at absorbing shock as hyaline cartilage. Elastic cartilage is found in the external ear and epiglottis, providing flexibility and maintaining shape, but it does not have the same shock-absorbing properties as hyaline cartilage. Therefore, hyaline cartilage is the best choice for a cartilage type that allows for smooth movement at joints and absorbs shock.
