TEAS version 7 quizlet science
1. Which of the following is a characteristic of a solution with high viscosity?
- A. It flows easily
- B. It has a low resistance to flow
- C. It has a high resistance to flow
- D. It does not mix with other liquids
Correct answer: C
Rationale: The correct answer is C: 'It has a high resistance to flow.' A solution with high viscosity exhibits a high resistance to flow. Viscosity measures the fluid's resistance to deformation or flow, with higher viscosity indicating thicker and slower-flowing fluids. Choice A is incorrect because high viscosity means the solution flows slowly, not easily. Choice B is incorrect as high viscosity implies a high resistance to flow, not a low one. Choice D is irrelevant to viscosity and does not describe a characteristic associated with high viscosity.
2. The hypodermis is primarily composed of which tissue?
- A. Adipose
- B. Connective
- C. Epithelial
- D. Muscle
Correct answer: A
Rationale: The hypodermis, also known as the subcutaneous layer, is primarily composed of adipose (fat) tissue. Adipose tissue in the hypodermis serves as an insulator, energy reserve, and cushioning for the body. Choice B, Connective tissue, is a broad category that includes various types of tissue like adipose, but the hypodermis is specifically rich in adipose tissue. Choice C, Epithelial tissue, is not the primary component of the hypodermis; it is mainly found covering body surfaces and lining cavities. Choice D, Muscle tissue, is not a major component of the hypodermis; muscle tissue is mainly located deeper in the body and serves in movement and support functions.
3. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?
- A. 0.5 m/s²
- B. 1 m/s²
- C. 2 m/s²
- D. 10 m/s²
Correct answer: B
Rationale: The acceleration of an object is given by the formula \(a = \frac{F}{m}\), where \(F\) is the net force acting on the object and \(m\) is the mass of the object. In this case, the net force acting on the box is 20 N, and the mass of the box is 10 kg. Plugging these values into the formula, we get \(a = \frac{20}{10} = 2\) m/s².
4. Which of the following is NOT a function of the skeletal system?
- A. Support and structure
- B. Production of red blood cells
- C. Storage of minerals like calcium
- D. Insulation of the body
Correct answer: D
Rationale: The skeletal system's primary functions include support and structure, protection of internal organs, movement facilitation, production of blood cells, and storage of minerals like calcium. Insulation of the body is not a function of the skeletal system. Insulation, typically involving fat under the skin, helps regulate body temperature but is not a direct function of the skeletal system. Choice B, the production of red blood cells, is a function of the skeletal system as it occurs in the bone marrow within the bones. Choices A and C are also correct functions of the skeletal system.
5. Which part of the brain is responsible for processing vision?
- A. Occipital lobe
- B. Frontal lobe
- C. Temporal lobe
- D. Parietal lobe
Correct answer: A
Rationale: The occipital lobe is the part of the brain responsible for processing visual information. Located at the back of the brain, the occipital lobe contains the primary visual cortex, which plays a crucial role in interpreting visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, decision-making, and motor control, not vision processing. The temporal lobe is responsible for auditory processing, memory, and emotion, not vision. The parietal lobe is involved in sensory integration, spatial awareness, and perception of stimuli, but not specifically for visual processing.
