TEAS Test 7 science quizlet
1. Which organelle is responsible for carrying out photosynthesis in plant cells?
- A. Golgi apparatus
- B. Mitochondria
- C. Chloroplasts
- D. Lysosomes
Correct answer: C
Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion or for use within the cell. It is not involved in photosynthesis. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in photosynthesis. C) Chloroplasts: Chloroplasts are the organelles responsible for carrying out photosynthesis in plant cells. They contain chlorophyll, a pigment that captures light energy and converts it into chemical energy in the form of glucose. D) Lysosomes: Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials and cellular debris. They are not involved in photosynthesis. Therefore, the correct answer is C) Chloroplasts, as they are specifically responsible for carrying out photosynthesis in plant
2. What is the relationship between the frequency and period of a wave?
- A. They are unrelated
- B. Frequency = Period
- C. Frequency = 1/Period
- D. Period = 1/Frequency
Correct answer: D
Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This relationship indicates that the period of a wave is the reciprocal of its frequency. Frequency refers to the number of complete cycles of a wave occurring in a unit of time, while the period is the time taken for one complete cycle of the wave to occur. As frequency and period are inversely related, the correct formula to express this relationship is Period = 1/Frequency. Choice A is incorrect as frequency and period are related. Choice B is incorrect as frequency and period are not equal. Choice C is incorrect as it suggests that frequency is directly proportional to period, which is not the case.
3. What is the sensory threshold?
- A. The smallest amount of stimulus required for an individual to feel a sensation
- B. The amount of stimulus required for an individual to feel pain
- C. The amount of stimulus required to cause an individual to move away from the stimulus
- D. The place from which the stimulus is coming
Correct answer: A
Rationale: The sensory threshold refers to the smallest amount of stimulus required for an individual to perceive or feel a sensation. It is the minimum level of stimulus intensity that is detectable by an individual. Choice B is incorrect because the sensory threshold is not specifically related to feeling pain but rather to perceiving any sensation. Choice C is incorrect as the sensory threshold is about perception and not necessarily physical reaction. Choice D is incorrect as it describes the source of the stimulus, not the threshold for perception.
4. Where is the scapula in relation to the olecranon?
- A. Distal
- B. Lateral
- C. Ventral
- D. Superior
Correct answer: D
Rationale: The correct answer is D: 'Superior.' The scapula is located superior to the olecranon. In anatomical terms, 'superior' refers to a position above or higher than a reference point. 'Distal' is a term used to describe a position farther away from the point of attachment or origin. 'Lateral' refers to a position further away from the midline of the body. 'Ventral' refers to the front or anterior side of the body. In this case, the scapula being superior to the olecranon means it is positioned above the olecranon bone.
5. What is the independent variable in the botanist's experiment?
- A. Temperature
- B. Root tissue
- C. Light exposure
- D. Root length
Correct answer: A
Rationale: In an experiment, the independent variable is the factor that is deliberately manipulated or changed by the researcher. The botanist is likely altering the temperature to observe its effect on the plants. Therefore, temperature is the independent variable in the botanist's experiment. Choice B, root tissue, is not the independent variable as it is not the factor being intentionally changed in the experiment. Choice C, light exposure, and choice D, root length, are also not the independent variables as they are not the factors being purposely manipulated by the researcher in this scenario.
