TEAS 7 Science Practice Test

1. Which of the following lobes in the cerebral cortex is primarily responsible for processing and integrating sensory information received from the rest of the body?

A. frontal lobe
B. occipital lobe
C. parietal lobe
D. temporal lobe

Correct answer: C

Rationale: The parietal lobe is the correct answer because it is primarily responsible for processing and integrating sensory information received from the rest of the body, including touch, pressure, temperature, and pain. This lobe plays a crucial role in spatial awareness, perception, and attention to sensory stimuli. It helps individuals make sense of the world around them and is essential for various sensory processes. The frontal lobe (choice A) is more associated with functions like reasoning, planning, and problem-solving. The occipital lobe (choice B) is responsible for processing visual information. The temporal lobe (choice D) is involved in functions like memory, auditory processing, and language comprehension, but it is not the primary lobe responsible for processing and integrating sensory information from the body.

2. During REM sleep, which type of brain wave activity is often seen and associated with dreaming?

A. Delta waves
B. Alpha waves
C. Beta waves
D. Theta waves

Correct answer: D

Rationale: Theta waves are the correct answer as they are often seen during REM (rapid eye movement) sleep, the stage of sleep closely related to dreaming. Theta waves have a frequency of 4-7 Hz and are typically present during deep relaxation, meditation, and light sleep stages. Delta waves (choice A) are associated with deep sleep stages, not REM sleep. Alpha waves (choice B) are present during wakefulness and relaxation but not predominantly during REM sleep. Beta waves (choice C) are associated with alertness, problem-solving, and active thinking, not specifically with REM sleep or dreaming.

3. Which of the following is a characteristic of an interneuron?

A. Forms neural circuits
B. Interacts with effectors
C. Sends impulses to the CNS
D. Functions as an efferent nerve cell

Correct answer: A

Rationale: The correct characteristic of an interneuron is that it forms neural circuits, connecting sensory and motor neurons within the central nervous system. Interneurons facilitate communication between different neurons in the central nervous system, helping in the processing and integration of signals. Choice B is incorrect as interneurons primarily interact with other neurons, not effectors. Choice C is incorrect as interneurons typically do not send impulses to the CNS; they operate within the CNS. Choice D is incorrect as interneurons are not efferent nerve cells; they are mainly involved in processing signals within the CNS rather than transmitting signals to effectors.

4. Which type of reasoning has the FBI agent used?

A. Deductive Reasoning
B. Conductive Reasoning
C. Quantitative Reasoning
D. Inductive Reasoning

Correct answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing general conclusions from specific observations or instances. In this case, the FBI agent is creating a theory based on observations of specific cases rather than applying a general rule to a specific situation (which would be deductive reasoning). Conductive reasoning is not a recognized type of reasoning, and quantitative reasoning involves interpreting and analyzing quantitative information.

5. What is the length of DNA that can code for a particular protein?

A. Chromosome
B. Nucleotide
C. Gene
D. Ribosome

Correct answer: C

Rationale: The correct answer is C: Gene. A gene is a specific segment of DNA that contains the information necessary to produce a particular protein. Genes are responsible for coding proteins, and each gene carries the instructions for a specific protein. Chromosomes consist of many genes and are not a specific length that codes for a protein. Nucleotides are the building blocks of DNA and are not a length that codes for a protein. Ribosomes are cellular organelles involved in protein synthesis and do not directly code for proteins.
