TEAS version 7 quizlet science

1. Which property of matter refers to the amount of space occupied by an object?

Correct answer: B

Rationale: Volume refers to the amount of space occupied by an object. It is a measure of the three-dimensional space that an object occupies. Mass, on the other hand, refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. In this context, volume is the most appropriate choice as it directly relates to the amount of space an object occupies.

2. Which system is responsible for transporting nutrients, gases, and wastes in the body?

Correct answer: C

Rationale: The circulatory system is responsible for transporting nutrients, gases, and wastes to and from the cells in the body. It includes the heart, blood vessels, and blood, which work together to distribute oxygen, nutrients, and remove waste products throughout the body. The respiratory system is primarily involved in gas exchange, the digestive system breaks down food for absorption, and the nervous system is responsible for transmitting signals throughout the body.

3. What is the process by which cells respond to external stimuli, such as chemicals, temperature, or touch, called?

Correct answer: A

Rationale: Signal transduction is the correct answer. It is the process by which cells respond to external stimuli like chemicals, temperature, or touch. When a cell receives a signal from its environment, it triggers a series of molecular events leading to a specific cellular response. This process involves transmitting signals from the cell surface to the interior, triggering various cellular activities. Homeostasis, on the other hand, refers to an organism's ability to maintain internal stability in response to external changes. Adaptation involves an organism adjusting to its environment over time through genetic changes or behavioral modifications, which is distinct from the process of cells responding to immediate external stimuli. Metabolism, although essential for cellular functions, is not specifically about cells responding to external stimuli but rather the biochemical processes involved in energy production, storage, and utilization within cells.

4. Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

Correct answer: C

Rationale: The parietal lobe is responsible for sensation, perception, and spatial reasoning. It plays a crucial role in processing sensory information, assisting in spatial orientation, and integrating various sensory inputs to create a comprehensive perception of the surrounding environment. The frontal lobe, although important for higher cognitive functions and motor skills, is not primarily responsible for sensation, perception, or spatial reasoning. The occipital lobe is mainly involved in visual processing, and the temporal lobe is primarily associated with auditory processing, memory, and emotions, making them incorrect choices for this question.

5. What type of chemical bond connects the oxygen and hydrogen atoms in a molecule of water?

Correct answer: D

Rationale: The correct answer is D, Covalent bond. Covalent bonds are formed between oxygen and hydrogen atoms in a water molecule. In a water molecule, each hydrogen atom forms a covalent bond with the oxygen atom, sharing electrons to achieve a stable configuration. Static bond (choice A) and Aquatic bond (choice B) are not valid types of chemical bonds. Ionic bond (choice C) involves the transfer of electrons between atoms of different electronegativities, which is not the case between oxygen and hydrogen in a water molecule.
