ATI TEAS Science Questions
1. Which of the following is an example of a pivot joint?
- A. Hip
- B. Neck
- C. Shoulder
- D. Elbow
Correct answer: B
Rationale: The correct answer is B: Neck. A pivot joint, as found in the neck, allows for rotational movement around a single axis. This type of joint is essential for movements like shaking your head 'no' or looking left and right. Choices A, C, and D are incorrect because the hip, shoulder, and elbow joints are examples of ball-and-socket joints, which allow for a wide range of motion in multiple directions, not just rotational movement around a single axis like a pivot joint.
2. What is the stage of mitosis during which the nuclear envelope reforms?
- A. Prophase
- B. Metaphase
- C. Telophase
- D. Cytokinesis
Correct answer: C
Rationale: During telophase, the nuclear envelope reforms around the separated sister chromatids at opposite poles of the cell. This stage marks the reversal of the processes that occurred during prophase, where the nuclear envelope breaks down. Metaphase is characterized by the alignment of chromosomes along the metaphase plate in the cell's center. Cytokinesis is the final step of cell division involving cytoplasmic division to form two daughter cells, but it does not involve the reformation of the nuclear envelope. Therefore, choice C (Telophase) is the correct answer as it specifically involves the reformation of the nuclear envelope, distinguishing it from the other stages of mitosis.
3. What is the structure that connects the ovary to the uterus in the female reproductive system?
- A. Urethra
- B. Fallopian tube
- C. Vagina
- D. Cervix
Correct answer: B
Rationale: The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes serve as a pathway for the egg to travel from the ovary to the uterus, where fertilization typically occurs. Options (A) Urethra, (C) Vagina, and (D) Cervix are not the structures responsible for connecting the ovary to the uterus, making them incorrect choices for this question.
4. What property of a substance remains constant regardless of the amount of the substance present?
- A. Mass
- B. Weight
- C. Density
- D. Volume
Correct answer: C
Rationale: The correct answer is C, Density. Density is a physical property of a substance that remains constant regardless of the amount of the substance present. Mass (Choice A) is the amount of matter in an object and can change depending on the amount of the substance. Weight (Choice B) is the force exerted on an object due to gravity and can vary with location. Volume (Choice D) is the amount of space occupied by a substance and can change if the amount of the substance changes.
5. Which of the following terms describes the enlargement of an organ or tissue?
- A. Dystrophy
- B. Atrophy
- C. Hypertrophy
- D. Eutrophy
Correct answer: C
Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.
