TEAS version 7 quizlet science
1. A pendulum swings back and forth. What type of energy conversion occurs during its motion?
- A. Potential energy to kinetic energy and vice versa
- B. Thermal energy to mechanical energy and vice versa
- C. Chemical energy to electrical energy and vice versa
- D. Nuclear energy to radiant energy and vice versa
Correct answer: A
Rationale: As the pendulum swings back and forth, it undergoes a continuous conversion between potential energy (at the highest point of the swing) and kinetic energy (at the lowest point of the swing). At the highest point, the pendulum has maximum potential energy due to its height above the ground. As it swings down, this potential energy is converted into kinetic energy, which is the energy of motion. At the lowest point of the swing, the pendulum has maximum kinetic energy and minimal potential energy. The process repeats as the pendulum swings back in the opposite direction, demonstrating the conversion between potential and kinetic energy. Choices B, C, and D are incorrect because the energy conversion in a swinging pendulum primarily involves changes between potential and kinetic energy, not thermal, chemical, electrical, nuclear, or radiant energy.
2. Which of the following describes a difference between cytosol and the mitochondrion?
- A. Cytosol is a membrane-bound organelle, but the mitochondrion is not
- B. Cytosol is part of the cytoplasm, but the mitochondrion is not
- C. The mitochondrion is a membrane-bound organelle, but cytosol is not
- D. The mitochondrion is part of the cytoplasm, but cytosol is not
Correct answer: C
Rationale: The mitochondrion is a membrane-bound organelle, while cytosol is the fluid part of the cytoplasm. This differentiation highlights that the mitochondrion has its own membrane structure separating it from the cytoplasm, whereas cytosol is not membrane-bound and represents the liquid portion of the cytoplasm. Choice A is incorrect because cytosol is not a membrane-bound organelle, and the mitochondrion is also not described accurately. Choice B is incorrect as cytosol is indeed part of the cytoplasm. Choice D is incorrect because both the mitochondrion and cytosol are part of the cytoplasm, but the mitochondrion is a membrane-bound organelle unlike cytosol.
3. Salts are formed by the reaction between:
- A. Two acids
- B. An acid and a base
- C. Two bases
- D. A metal and a nonmetal only
Correct answer: B
Rationale: Salts are formed by the reaction between an acid and a base. This reaction is known as a neutralization reaction. In this reaction, the acid donates a proton (H+) to the base, resulting in the formation of water and a salt as the products. Choice A is incorrect because salts are not formed by the reaction of two acids. Choice C is incorrect as salts are not produced by the reaction of two bases. Choice D is incorrect because while salts can be formed from the reaction between a metal and a nonmetal, it is not the only way salts are produced.
4. What is the structure that connects the ovary to the uterus in the female reproductive system?
- A. Urethra
- B. Fallopian tube
- C. Vagina
- D. Cervix
Correct answer: B
Rationale: The fallopian tubes are the structures that connect the ovaries to the uterus in the female reproductive system. These tubes serve as a pathway for the egg to travel from the ovary to the uterus, where fertilization typically occurs. Options (A) Urethra, (C) Vagina, and (D) Cervix are not the structures responsible for connecting the ovary to the uterus, making them incorrect choices for this question.
5. Which of the following best describes a group of cells working together?
- A. Organelle
- B. Tissue
- C. Organ
- D. Organ system
Correct answer: B
Rationale: The correct answer is B: Tissue. Tissue is a group of cells that work together to perform a specific function. Organelle refers to specialized structures within a cell, organ is a structure made up of different types of tissues working together, and organ system is a group of organs working together to perform complex functions. Therefore, tissue is the most appropriate term to describe a group of cells working together.
