ATI TEAS 7
English TEAS Practice Test
1. Which of the following prefixes would be used to indicate that something is inside or within?
- A. intra–
- B. trans–
- C. anti–
- D. hyper–
Correct answer: A
Rationale: The correct answer is A: "intra–". The prefix "intra-" is used to indicate that something is inside or within. For example, "intracellular" means within a cell, and "intrapersonal" means within oneself. Choice B, "trans–", typically indicates across, beyond, or through, not inside or within. Choice C, "anti–", is used to indicate against or opposed to. Choice D, "hyper–", usually denotes excessive or above normal levels, not inside or within.
2. Which type of muscle tissue has a unique branching network and is found in the heart?
- A. Skeletal muscle
- B. Cardiac muscle
- C. Smooth muscle
- D. Multifidus muscle
Correct answer: B
Rationale: The correct answer is B, Cardiac muscle. Cardiac muscle is the type of muscle tissue that has a unique branching network and is found in the heart. This type of muscle is involuntary and contracts rhythmically to pump blood throughout the body. Skeletal muscle, choice A, is attached to bones and is responsible for voluntary movements. Smooth muscle, choice C, is found in the walls of internal organs and blood vessels, playing a role in involuntary movements. Multifidus muscle, choice D, is a specific muscle in the back that helps with spinal stability, unrelated to the unique branching network found in cardiac muscle.
3. Identify the indirect object in the following sentence: 'He gave his mother a bouquet of flowers.'
- A. mother
- B. bouquet
- C. flowers
- D. gave
Correct answer: A
Rationale: In the sentence 'He gave his mother a bouquet of flowers,' the indirect object is 'his mother' because she is the recipient of the action of giving. The direct object is 'a bouquet of flowers' because it is the thing being given. The verb 'gave' is the action being performed. Choice B, 'bouquet,' is incorrect as it is the direct object, not the indirect object. Choice C, 'flowers,' is incorrect as it is part of the direct object phrase. Choice D, 'gave,' is incorrect as it is the verb indicating the action, not an object.
4. Homologous structures are those that:
- A. Have the same function but different origins
- B. Have different functions but the same origin
- C. Are similar in appearance and function due to shared ancestry
- D. Are identical in both appearance and function
Correct answer: C
Rationale: Homologous structures are defined as anatomical features that are similar in appearance and function due to shared ancestry. This means that these structures are inherited from a common ancestor and may have evolved to fulfill different functions in different species. Option A, which mentions structures with the same function but different origins, describes analogous structures, not homologous ones. Option B, which refers to structures with different functions but the same origin, actually characterizes vestigial structures. Option D, stating that structures are identical in appearance and function, does not necessarily imply homology; such structures could result from convergent evolution rather than shared ancestry. Understanding homologous structures provides insights into the evolutionary relationships between different species and supports the concept of common descent.
5. What is the SI unit of measurement for momentum?
- A. Newton (N)
- B. Kilogram-meter per second (kg·m/s)
- C. Joule (J)
- D. Newton-second (N·s)
Correct answer: B
Rationale: The correct SI unit of measurement for momentum is kilogram-meter per second (kg·m/s). Momentum is a vector quantity that is calculated by multiplying an object's mass (in kilograms) by its velocity (in meters per second), resulting in the unit kg·m/s. This unit represents the quantity of motion an object possesses, taking into account both the mass and velocity of the object. Choice A, Newton (N), is the unit of force, not momentum. Choice C, Joule (J), is the unit of energy, not momentum. Choice D, Newton-second (N·s), is the unit of impulse, not momentum.
