TEAS 7 science practice questions

1. Differentiate between epithelial and connective tissue.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ. Epithelial tissue acts as a barrier to protect underlying tissues and organs, while connective tissue connects, supports, and separates different types of tissues and organs in the body. Choice A is incorrect as connective tissue supports and binds other tissues, not just tendons. Choice C is incorrect because connective tissue does not support muscle contraction; it provides support to various structures in the body. Choice D is incorrect as the size of a tissue type does not define its function; epithelial tissue and connective tissue serve different purposes in the body.

2. What is the purpose of the periosteum, the tough outer layer of bone?

Correct answer: B

Rationale: The periosteum, the tough outer layer of bone, serves the purpose of providing protection to the bone and nourishing it through the blood vessels it contains. It acts as a protective layer for the bone structures. Choices A, C, and D are incorrect because the periosteum does not produce red blood cells (which is the function of bone marrow), form joint surfaces (which is typically the role of articular cartilage), or store minerals (which is primarily done by bone tissue itself and not the periosteum).

3. Which of the following is an example of an aromatic hydrocarbon?

Correct answer: B

Rationale: Benzene is indeed an example of an aromatic hydrocarbon. Aromatic hydrocarbons are characterized by having a cyclic structure with alternating single and double bonds (pi bonds). Benzene fits this description, making it aromatic. On the other hand, ethane, propane, and butene are aliphatic hydrocarbons, which do not have the distinct cyclic structure of aromatic hydrocarbons. Ethane, propane, and butene are aliphatic hydrocarbons, which contain only single bonds and are not cyclic in nature. Therefore, they are not examples of aromatic hydrocarbons.

4. An object is initially at rest. Which of the following will definitely NOT cause it to move?

Correct answer: B

Rationale: The correct answer is B because if an object is initially at rest and no force is acting on it, it will remain at rest due to Newton's First Law of Motion. This law states that an object at rest will stay at rest unless acted upon by an external force. Choices A, C, and D all involve forces acting on the object, which would cause it to move according to Newton's laws of motion. Choice A, a constant force acting on the object, would cause it to move at a constant velocity. Choice C, a force that increases in magnitude over time, would accelerate the object. Choice D, a force that decreases in magnitude over time, would decelerate the object.

5. Which organ in the human body is the largest and is responsible for detoxification, metabolism, and storage of nutrients?

Correct answer: B

Rationale: The liver is the largest internal organ in the human body and is responsible for detoxification, metabolism, storage of nutrients, and various other essential functions. It plays a critical role in maintaining overall health by processing nutrients, filtering blood, and detoxifying harmful substances. While the skin is the largest organ by surface area, the liver is the largest internal organ and is crucial for various physiological processes. The heart is responsible for pumping blood, the lungs for respiration, and the skin for protection and temperature regulation, but they do not perform the functions specified in the question.
