TEAS version 7 quizlet science
1. What is the significance of cell division?
- A. Growth and repair of tissues
- B. Sexual reproduction
- C. Genetic diversity
- D. All of the above
Correct answer: D
Rationale: Cell division is a fundamental process that serves multiple critical functions in living organisms. It is essential for the growth and repair of tissues by enabling the formation of new cells to replace old or damaged ones. Moreover, cell division plays a pivotal role in sexual reproduction as it is involved in the production of gametes necessary for fertilization. Additionally, cell division contributes to genetic diversity through processes like meiosis, which leads to the formation of genetically distinct gametes. Therefore, the correct answer is D, 'All of the above,' as cell division is significant for growth, repair, sexual reproduction, and genetic diversity. Choices A, B, and C are incorrect because they each represent only one aspect of the significance of cell division, whereas the correct answer encompasses all the essential roles that cell division plays in living organisms.
2. Muscle tissues often require quick bursts of energy. As a result, which of the following organelles would be most likely to be found in higher than normal amounts in muscle cells?
- A. ribosomes
- B. chloroplasts
- C. vacuoles
- D. mitochondria
Correct answer: D
Rationale: Muscle tissues require quick bursts of energy for activities such as contraction and relaxation. Mitochondria are known as the powerhouse of the cell, producing energy in the form of ATP through cellular respiration. Therefore, muscle cells would require higher amounts of mitochondria to meet their energy demands. Ribosomes are involved in protein synthesis and are not directly related to energy production. Chloroplasts are found in plant cells and are responsible for photosynthesis, not in animal muscle cells. Vacuoles are primarily involved in storage, maintaining turgor pressure, and digestion, but they are not the main organelles involved in energy production.
3. What is the main function of the large intestine?
- A. To absorb proteins
- B. To absorb water and form feces
- C. To produce enzymes for digestion
- D. To store fat
Correct answer: B
Rationale: The main function of the large intestine is to absorb water and form feces from waste material. Choice A is incorrect because the absorption of proteins primarily occurs in the small intestine. Choice C is incorrect as the production of enzymes for digestion mainly takes place in the pancreas and small intestine. Choice D is incorrect as the storage of fat is not a primary function of the large intestine.
4. Which property of a substance refers to its ability to be hammered or pressed into thin sheets without breaking?
- A. Malleability
- B. Ductility
- C. Viscosity
- D. Conductivity
Correct answer: A
Rationale: Malleability is the correct answer as it is the property of a substance that allows it to be hammered or pressed into thin sheets without breaking. This property is crucial for materials like metals that need to be shaped without breaking. Ductility, on the other hand, refers to the ability of a substance to be drawn into thin wires, not hammered into sheets. Viscosity is a measure of a fluid's resistance to flow, indicating its thickness or thinness, and is unrelated to the ability to be hammered. Conductivity, on the other hand, refers to a substance's ability to conduct electricity or heat, which is not related to its ability to be hammered or pressed into thin sheets.
5. Which group of elements is known for their vibrant colors and is commonly used in fireworks?
- A. Noble gases
- B. Alkali metals
- C. Halogens
- D. Transition metals
Correct answer: D
Rationale: The correct answer is D: Transition metals. Transition metals are known for their vibrant colors and are commonly used in fireworks due to their ability to emit specific colors of light. The diverse electronic configurations of transition metals allow them to produce a variety of hues, making them ideal for creating colorful displays in fireworks. Choice A, Noble gases, do not typically produce vibrant colors in fireworks as they are colorless and odorless gases. Choice B, Alkali metals, are not known for their colorful displays in fireworks. Choice C, Halogens, can produce colors in fireworks, but they are not as commonly used for their vibrant hues compared to transition metals.
