ATI TEAS 7 science review

1. Classifications of human tissues exclude:

Correct answer: D

Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.

2. Which of these pairs represents an example of convergent evolution?

Correct answer: B

Rationale: Convergent evolution refers to the process by which different species independently evolve similar traits or characteristics due to similar environmental pressures. In the case of bats and birds, both have evolved wings for flight despite not sharing a recent common ancestor with wings. Bats are mammals, while birds are avians, yet they both have wings adapted for flight, which is a classic example of convergent evolution. A) Humans and chimpanzees share a common ancestor and have not independently evolved similar traits. C) Dolphins and sharks are not closely related, and their similarities are due to adaptations to their aquatic environment rather than convergent evolution. D) Snakes and earthworms belong to different classes (reptiles and annelids, respectively) and do not share recent common ancestors, making their similarities not a result of convergent evolution.

3. What is the primary function of coronary arteries?

Correct answer: B

Rationale: The primary function of coronary arteries is to supply oxygenated blood to the heart muscle itself. The heart is a muscle that needs a constant supply of oxygen and nutrients to function properly. Coronary arteries branch off the aorta and specifically deliver oxygenated blood to the heart muscle, ensuring its proper function. Choice A is incorrect because coronary arteries do not deliver blood throughout the entire body but specifically to the heart. Choice C is incorrect as coronary arteries carry oxygenated blood away from the heart. Choice D is incorrect as the primary function of the coronary arteries is not to regulate blood pressure but rather to provide oxygenated blood to the heart muscle.

4. Choose the correct pronoun to complete the sentence: 'Neither Michael nor Sarah ____ their homework finished yet.'

Correct answer: B

Rationale: In this sentence, 'neither' is followed by two subjects, 'Michael' and 'Sarah.' When 'neither' is followed by two singular subjects joined by 'nor,' the verb should agree with the subject closer to the verb, which is 'Sarah' in this case. Therefore, the correct pronoun to complete the sentence is 'have.' Choice A, 'has,' is incorrect because it is singular and does not agree with the plural subject 'Sarah.' Choice C, 'are having,' is incorrect as it changes the sentence structure and does not fit grammatically. Choice D, 'does have,' is incorrect as 'does' is unnecessary and 'have' does not agree with the singular verb 'does.'

5. Which of the following are the two major zones of the respiratory system?

Correct answer: D

Rationale: The two major zones of the respiratory system are the conducting zone and the respiratory zone. The conducting zone encompasses structures like the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles, which serve to transport air into the lungs. On the other hand, the respiratory zone includes the respiratory bronchioles, alveolar ducts, and alveoli, where the crucial gas exchange process between the air in the lungs and the blood occurs. Choices A, B, and C are incorrect as they do not represent the major zones of the respiratory system but rather individual structures within the system.
