Answer the following question given this paragraph: What happens when forces of evolution work over a long period of time? The answer is macroevolution. An example is the evolution of a new species. Q: What happens when forces of evolution work over a long period of time? Choices: - substantial evolution - Microevolution - developmental evolution - macroevolution A:
macroevolution
Answer the following question given this paragraph: It can be. Achondroplasia is the most common form of dwarfism in humans, and it is caused by a dominant mutation. The mutation can be passed from one generation to the next. Over 95% of unrelated individuals with Achondroplasia have the same mutation, making it one of the most common mutations in the human genome. Why?. Q: What is the most common form of dwarfism in humans? Choices: - anemia - alopecia - malnutrition - achondroplasia A:
achondroplasia
Q: Answer the following question given this paragraph: Each kind of pigment absorbs specific wavelengths (colors) of light (dashed lines). Sunlight contains many different wavelengths, which you see when they separate into a rainbow. Not all colors of light are used in photosynthesis (solid line). Most plants, algae, and photosynthetic bacteria appear green because they reflect green wavelengths. Their pigments have absorbed the violet-blue and red wavelengths. The amount of photosynthesis depends on the wavelength of light available. Beta-carotene is another type of pigment that absorbs sunlight. Q: Sunlight contains many different wavelengths, which you see when they separate into what? Choices: - shadows - charges - sounds - rainbow A:
A: rainbow
Question: Answer the following question given this paragraph: Earth has north and south magnetic poles like a bar magnet. Earth's magnetic poles are not the same as the geographic poles. Q: Earth's magnetic north and south poles are not the same as what? Choices: - equatorial planes - geographic currents - geographic hemispheres - geographic poles A:
Answer: geographic poles

Answer the following question given this paragraph: The weathering of rocks and minerals can be mechanical or chemical. Mechanical weathering changes the size of a mineral or rock. Mechanical weathering does not change the chemical composition of that material. Chemical weathering changes the composition of a mineral or rock. Different types of weathering can alter the same material. Soil forms on top of rock. The type of soil that forms depends on the environment of the region. For example, warm and wet climates form different soils than cold and dry climates. A profile through the soil shows different horizons. Topsoil is the most important layer for crops. Water, ice, wind, and gravity create or modify landforms on Earth's surface. These agents can erode or deposit features that indicate their presence. Erosion by water and ice lowered and rounded the Appalachians. These old mountains no longer look like the Himalaya. Someday the Himalaya may look like the Appalachians do now. Q: What kind of weathering changes the size of a mineral or rock but does not change its chemical composition? Choices: - molecular weathering - chemical reaction - radiation - mechanical weathering A:
**Answer**
mechanical weathering

Answer the following question given this paragraph: Metamorphic rocks form when an existing rock is changed by heat or pressure. The minerals in the rock change but do not melt. The rock experiences these changes within the Earth. Q: Metamorphic rocks form when an existing rock is changed by heat or what? Choices: - radiation - chemical reaction - cold - pressure A:
**Answer**
pressure
