ATI TEAS Practice Science Test

1. Which structure protects the lungs?

Correct answer: B

Rationale: The ribcage is the correct answer. It protects the lungs by providing structural support and shielding them from injury. The femur is a bone in the thigh and does not protect the lungs. The scapula is a shoulder blade bone, and the skull protects the brain, not the lungs.

2. Which organ is responsible for filtering blood and removing waste products?

Correct answer: B

Rationale: The correct answer is the kidneys. The kidneys filter blood and remove waste products through the formation of urine. The liver primarily functions in detoxification and metabolism. The spleen is involved in blood filtering and immune function. The pancreas produces digestive enzymes and insulin, not involved in filtering blood.

3. How does RNA polymerase differ from DNA polymerase?

Correct answer: B

Rationale: Rationale: A) This statement is incorrect. RNA polymerase and DNA polymerase are not identical in function and structure. They have different roles in the cell. B) This statement is correct. Unlike DNA polymerase, RNA polymerase does not require a primer to initiate RNA synthesis. RNA polymerase can start the synthesis of RNA de novo. C) This statement is incorrect. RNA polymerase is specialized for synthesizing RNA, not DNA. DNA polymerase is responsible for synthesizing DNA. D) This statement is correct. RNA polymerase can only synthesize RNA, while DNA polymerase is responsible for synthesizing DNA.

4. Which of the following is NOT a function of the muscular system?

Correct answer: D

Rationale: The muscular system is responsible for movement, maintaining posture, and generating heat. Regulating blood sugar levels is not a function of the muscular system. This function is primarily carried out by the endocrine system, specifically the pancreas and its production of insulin and glucagon. Choices A, B, and C are all correct functions of the muscular system as they involve the contraction and relaxation of muscles to produce movement, support the body's structure, and generate heat as a byproduct of muscle activity.

5. Which of the following is an example of a zoonotic disease?

Correct answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.
