ATI TEAS Science Test Questions

Question 1 of 5

Are red hair and a height of six feet part of an individual's genotype or phenotype?

Correct Answer: D

Rationale: In the context of genetics, genotype refers to an individual's genetic makeup, while phenotype refers to the observable characteristics resulting from the interaction of the genotype with the environment. Red hair and a height of six feet are observable characteristics, making them part of the individual's phenotype. Therefore, both red hair and height are aspects of the individual's phenotype. Choices A and B are incorrect as they incorrectly assign one characteristic to the genotype and the other to the phenotype, which is not accurate. Choice C is incorrect as it states that both characteristics describe the genotype, which is inaccurate as they are observable traits. The correct answer is D, as both red hair and height are observable traits or characteristics, falling under the definition of phenotype in genetics.

Question 2 of 5

When defending a scientific argument, which technique is most effective?

Correct Answer: B

Rationale: The most effective technique when defending a scientific argument is to show the results of scientific experiments that support your argument. In the realm of science, evidence-based support is crucial. By presenting concrete data and experimental results, you provide a convincing and reliable foundation for your argument. This method allows others to review, replicate, and verify the findings, thus strengthening the credibility of your position. Choices A, C, and D are not as effective as choice B because citing other scientists who agree with your argument (Choice A) may not carry the same weight as empirical evidence, describing your scientific credentials, education, and past accomplishments (Choice C) may not directly address the validity of your argument, and pointing out that no one has come up with a proven alternative explanation (Choice D) does not provide direct evidence supporting your argument.

Question 3 of 5

What is the primary function of Bartholin's glands?

Correct Answer: B

Rationale: Bartholin's glands are two small glands located on each side of the vaginal opening. Their primary function is to secrete fluids that help lubricate the vagina during sexual arousal. This lubrication helps to reduce friction and discomfort during sexual activity, making intercourse more comfortable and pleasurable. Choices A, C, and D are incorrect because Bartholin's glands do not secrete hormones to respond to stress, control growth and development, or stimulate the development of T cells. Their main role is specifically related to vaginal lubrication.

Question 4 of 5

Which of the following statements best defines an organelle?

Correct Answer: C

Rationale: The correct answer is C: 'Specialized structures within a cell.' An organelle is a specialized subunit within a cell that has a specific function. Organelles are membrane-bound structures found within the cytoplasm of eukaryotic cells, each performing distinct roles that contribute to the overall functioning of the cell. Choices A, B, and D are incorrect. Option A describes the glycocalyx, which is a layer of polysaccharides outside the plasma membrane of cells. Option B refers to prions, abnormal infectious proteins. Option D defines an organ, a collection of tissues used to serve a specific function, rather than an organelle within a cell.

Question 5 of 5

In the human skeleton, which of the following lists some of the vertebrae in descending order?

Correct Answer: A

Rationale: The correct order of some of the vertebrae in the human skeleton in descending order is Atlas, Axis, Thoracic, Lumbar, Sacral, Coccyx. This sequence follows the typical arrangement from the top of the spine down towards the pelvis. Choice B is incorrect as it does not follow the descending order of vertebrae. Choice C is incorrect as it starts with Thoracic which is not the first vertebra in the descending order. Choice D is incorrect as it starts with Coccyx which is the last vertebra in the descending order.
