ATI TEAS Practice Test Science Questions

Question 1 of 5

Which type of blood cell is responsible for clotting?

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.

Question 2 of 5

An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?

Correct Answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.

Question 3 of 5

Which of the following is a function of the liver?

Correct Answer: B

Rationale: The correct function of the liver is to store bile. Bile is produced in the liver and stored in the gallbladder until it is needed to aid in the digestion of fats. While the liver does produce bile, its primary role is to store and release it. Choices A, C, and D are incorrect. Producing digestive enzymes is mainly the function of the pancreas, filtering waste products from the blood is primarily done by the kidneys, and transporting nutrients to cells is typically associated with the circulatory system rather than the liver.

Question 4 of 5

What type of bond is present in salt?

Correct Answer: A

Rationale: The correct answer is 'Ionic.' Ionic bonds are formed in salts through the transfer of electrons between atoms, leading to the attraction between positively and negatively charged ions. This results in a stable ionic compound, such as common table salt (sodium chloride). Nonpolar covalent, polar covalent, and peptide bonds are not typically found in salts. Nonpolar covalent bonds involve the equal sharing of electrons, polar covalent bonds involve unequal sharing of electrons, and peptide bonds are specific to proteins, not salts.
