ATI TEAS Science Test Questions
Question 1 of 5
Which of the following is an example of a tissue?
Correct Answer: B
Rationale: The correct answer is 'B: liver.' The liver is an example of a tissue. Tissues are groups of cells that work together to perform specific functions in the body. The liver is made up of different types of cells that work together to carry out various essential functions, such as detoxification, metabolism, and storage of nutrients. Option A (chloroplasts) refers to organelles, not tissues. Option D (hamstring) is a muscle, not a tissue. Option C (mammal) represents a higher level of organization than tissues, as it refers to a classification of organisms, not a specific tissue type.
Question 2 of 5
To which of the following bone types do the spine and hips belong?
Correct Answer: B
Rationale: The correct answer is B: Irregular bones. The spine and hips belong to the category of irregular bones. Irregular bones have complex shapes that do not fit into other bone type categories. These bones serve functions such as support and protection, and their shapes vary depending on their specific roles in the body. Choice A, curved bones, is incorrect because bones like ribs are typically described as curved, not the spine and hips. Choice C, flat bones, is incorrect as flat bones include the skull and ribs, but not the spine and hips. Choice D, long bones, is also incorrect because long bones include bones like the femur and humerus, which are elongated with a shaft and distinct ends, unlike the spine and hips.
Question 3 of 5
Which of the following functions is NOT performed by the integumentary system, the skin?
Correct Answer: D
Rationale: The integumentary system, which includes the skin, performs various functions like protecting internal tissues from injury, waterproofing the body, and helping regulate body temperature. The function of returning fluid to the blood vessels is primarily associated with the lymphatic system, not the integumentary system. The skin contributes to fluid balance by regulating sweating and preventing excessive water loss, but it does not directly return fluid to the blood vessels, making this the correct answer. Choices A, B, and C are functions directly related to the integumentary system and are essential for maintaining the body's overall health and well-being.
Question 4 of 5
During the process of oogenesis, primary oocytes produce:
Correct Answer: B
Rationale: During the process of oogenesis, primary oocytes undergo meiosis to develop into secondary oocytes, which are the matured eggs released during ovulation for potential fertilization. Therefore, primary oocytes produce eggs, not sperm, oogonia, or stem cells, during oogenesis. Choice A (sperm) is incorrect as sperm is produced through spermatogenesis in males. Choice C (oogonia) is incorrect as oogonia are the cells that give rise to primary oocytes but are not the direct product of primary oocytes. Choice D (stem cells) is incorrect as primary oocytes do not directly produce stem cells during oogenesis.
Question 5 of 5
What is essential for an experiment to be considered successful?
Correct Answer: C
Rationale: For an experiment to be considered successful, it is essential that the data collected and results obtained can be reproduced or replicated by others. This reproducibility ensures the reliability and validity of the experiment's findings. It allows for independent verification of the results and contributes to the overall scientific rigor of the study. While having a reasonable hypothesis, a well-written lab report, and computer-aided statistical analysis are important aspects of an experiment, the ability to reproduce the data is crucial for establishing the experiment's credibility and success. Without reproducibility, the findings may not be reliable, and the experiment's outcomes cannot be verified independently, leading to doubts about its validity.
