ATI TEAS 7
English Grammar
1. Which word is misspelled?
- A. accommodate
- B. acquiesce
- C. circumstance
- D. indelible
Correct answer: D
Rationale: "Indelible" is spelled correctly, while "circumstance" should be "circumstance."
2. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?
- A. 60 cu cm
- B. 120 cu cm
- C. 150 cu cm
- D. 180 cu cm
Correct answer: C
Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.
3. Which respiratory structure is responsible for the humidification and warming of inhaled air?
- A. Trachea
- B. Larynx
- C. Nasal passages
- D. Bronchi
Correct answer: c
Rationale: The correct answer is C: Nasal passages. The nasal passages are lined with mucous membranes that produce mucus to humidify and warm the inhaled air before it reaches the lungs. This process helps to protect the delicate lung tissues from drying out and becoming irritated. The trachea, larynx, and bronchi play important roles in the respiratory system, but specifically, the nasal passages are primarily responsible for humidifying and warming the air as it enters the body.
4. What is the relationship between the Pauli exclusion principle and the structure of the atom?
- A. It defines the maximum number of electrons allowed in each energy level.
- B. It explains why oppositely charged particles attract each other.
- C. It describes the wave-particle duality of electrons.
- D. It determines the arrangement of protons and neutrons in the nucleus.
Correct answer: A
Rationale: It defines the maximum number of electrons allowed in each energy level. The Pauli exclusion principle states that no two electrons in an atom can occupy the same quantum state, which explains the specific sequence and structure of electron shells within the atom.
5. What is the process of transporting molecules across the cell membrane against a concentration gradient called?
- A. Diffusion
- B. Osmosis
- C. Active transport
- D. Facilitated diffusion
Correct answer: C
Rationale: Rationale: A) Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, which does not require energy input. B) Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. C) Active transport is the process of transporting molecules across the cell membrane against a concentration gradient, requiring energy in the form of ATP to move substances from an area of lower concentration to an area of higher concentration. D) Facilitated diffusion is a type of passive transport that involves the use of transport proteins to move molecules across the cell membrane from an area of higher concentration to an area of lower concentration, without the need for energy input.
6. Which element is a component of baking soda and is important for maintaining pH balance in the body?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Sodium bicarbonate
Correct answer: D
Rationale: Sodium bicarbonate acts as a base and helps regulate pH in various biological systems
