ATI TEAS 7 English quizlet
1. Identify the noun in the following sentence: The aroma of freshly baked bread filled the kitchen.
- A. filled
- B. kitchen
- C. aroma
- D. freshly
Correct answer: C
Rationale: A noun is a word that names a person, place, thing, or idea. In the given sentence, 'aroma' is the noun as it names a specific thing, in this case, a smell. 'Filled' is a verb showing an action, 'kitchen' is a place, and 'freshly' is an adverb modifying the adjective 'baked.' Therefore, 'aroma' is the correct choice as the noun in this sentence.
2. Which mineral is crucial for bone strength and is stored in bones and teeth?
- A. Calcium
- B. Iron
- C. Magnesium
- D. Potassium
Correct answer: A
Rationale: Calcium is crucial for bone strength as it is a major mineral stored in bones and teeth. It plays a vital role in maintaining bone density and strength, making it essential for overall bone health. Calcium is essential for various physiological functions, including muscle contraction, nerve transmission, and blood clotting. Inadequate calcium intake can lead to conditions like osteoporosis, where bones become weak and brittle. Iron (Choice B) is important for transporting oxygen in the blood, but it is not stored in bones and does not play a significant role in bone strength. Magnesium (Choice C) is essential for bone health, but it is not primarily stored in bones and teeth. Potassium (Choice D) is crucial for various physiological functions, such as fluid balance and muscle function, but it is not a major mineral stored in bones and teeth for bone strength.
3. Which type of blood cell is responsible for clotting?
- A. Red blood cells
- B. Platelets
- C. White blood cells
- D. Plasma
Correct answer: B
Rationale: Platelets are responsible for blood clotting. They help prevent excessive bleeding by forming clots at the site of blood vessel injuries. Platelets release chemicals that initiate the clotting process, leading to the formation of a stable clot that stops bleeding. Red blood cells are primarily responsible for carrying oxygen throughout the body and do not play a direct role in clotting. White blood cells are part of the immune system, fighting off infections and foreign invaders. Plasma is the liquid component of blood that carries various substances such as nutrients, hormones, and waste products, but it is not directly involved in clotting.
4. Which of the following is produced by Natural Killer Cells to create pores for target cell rupture?
- A. Interferon
- B. Apoptosis
- C. Perforin
- D. Antibody
Correct answer: C
Rationale: The correct answer is C, Perforin. Natural Killer cells release perforin, which forms pores in the membrane of target cells, leading to their lysis. Interferon (choice A) is a protein released by cells in response to viral infections, apoptosis (choice B) is programmed cell death, and antibodies (choice D) are produced by B cells to neutralize pathogens but are not directly involved in creating pores for cell rupture like perforin.
5. What are the subdivisions of the dorsal cavity, located at the back of the human body?
- A. Cranial and spinal
- B. Dorsal and ventral
- C. Lateral and proximal
- D. Inferior and superior
Correct answer: A
Rationale: The correct answer is A: Cranial and spinal. The dorsal cavity, situated at the back of the human body, is divided into the cranial cavity (housing the brain) and the spinal cavity (housing the spinal cord). Choices B, C, and D are incorrect as they do not represent the correct subdivisions of the dorsal cavity. Option B (Dorsal and ventral) is incorrect as it confuses the dorsal cavity with the dorsal and ventral body planes. Option C (Lateral and proximal) and option D (Inferior and superior) are incorrect as they refer to different anatomical terms that do not apply to the subdivisions of the dorsal cavity.
