English Grammar
1. Identify the interrogative sentence in the following options:
- A. The delicious pie disappeared quickly.
- B. What is your favorite color?
- C. Please open the window.
- D. He ran as fast as he could.
Correct answer: B
Rationale: An interrogative sentence asks a question and typically ends with a question mark.
2. What is the scientific term for a muscle that helps another muscle perform its action?
- A. Agonist
- B. Antagonist
- C. Synergist
- D. Fixator
Correct answer: C
Rationale: The correct answer is C: Synergist. A synergist muscle is a muscle that assists the prime mover (agonist) in performing its action by stabilizing joints or contributing extra force to the movement. Antagonist muscles oppose the action of the prime mover, while fixator muscles stabilize the origin of the prime mover to allow efficient movement. Understanding the roles of these muscles is essential in comprehending how various muscle groups work together to produce coordinated movements.
3. Which statement accurately describes the relationship between electron configuration and the periodic table?
- A. Elements within the same period have similar electron configurations.
- B. Elements within the same group have similar electron configurations in their outermost shell.
- C. Electron configuration has no influence on an element's position on the periodic table.
- D. The number of electron shells an element has determines its group on the periodic table.
Correct answer: B
Rationale: Elements within the same group have similar electron configurations in their outermost shell. This explains why elements in the same group often share similar chemical properties.
4. A table shows the average blood pressure readings for different age groups. How do you determine the highest average systolic pressure?
- A. Find the largest number in the "systolic pressure" column.
- B. Compare the means (averages) of each age group.
- C. Add all systolic pressure values and divide by the total number of patients.
- D. Subtract the lowest systolic pressure from the highest.
Correct answer: A
Rationale: Rationale: - To determine the highest average systolic pressure, you need to identify the highest individual systolic pressure reading in the dataset. - Option A instructs you to find the largest number in the "systolic pressure" column, which directly addresses the task of identifying the highest systolic pressure reading. - Comparing means (Option B) would not necessarily give you the highest individual systolic pressure reading, as averages can be influenced by the distribution of values within each age group. - Adding all systolic pressure values and dividing by the total number of patients (Option C) would give you the overall average systolic pressure, not the highest individual reading. - Subtracting the lowest systolic pressure from the highest (Option D) would give you the range of systolic pressures, not specifically the highest individual reading. Therefore, the correct approach to determine the highest average systolic pressure
5. What is the building block of RNA?
- A. Amino acid
- B. Nucleotide
- C. Protein
- D. Fatty acid
Correct answer: B
Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.
6. The T wave on an ECG corresponds to:
- A. Atrial depolarization
- B. Ventricular depolarization
- C. Atrial repolarization
- D. Ventricular repolarization
Correct answer: D
Rationale: The T wave on an ECG corresponds to ventricular repolarization. During this phase, the ventricles are resetting electrically after contraction, preparing for the next heartbeat. Atrial depolarization is represented by the P wave, ventricular depolarization by the QRS complex, and atrial repolarization is typically hidden within the QRS complex. Therefore, option D, 'Ventricular repolarization,' is the correct choice when identifying the electrical activity represented by the T wave on an ECG.
