Q: Answer the following question given this paragraph: Q: All new alleles are formed by what types of mutations? Choices: - chaotic - systemic - ordinary - random A:
A: random

Q: Answer the following question given this paragraph: Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains . During the light reactions, water is used and oxygen is produced. These reactions can only occur during daylight as the process needs sunlight to begin. Q: What is produced during the light reactions in photosynthesis? Choices: - carbon - waste - nitrogen - oxygen A:
A: oxygen

Q: Answer the following question given this paragraph: A fluorescent light bulb produces visible light by fluorescence. Fluorescence occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light. The compact fluorescent light bulb (CFL) in the Figure below contains mercury gas that gives off ultraviolet light when electricity passes through it. The inside of the bulb is coated with a substance called phosphor. Phosphor absorbs the ultraviolet light and then gives off most of the energy as visible light. Q: What light-producing process occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light? Choices: - candescence - resistance - luminescence - fluorescence A:
A: fluorescence

Q: Answer the following question given this paragraph: Stress is the force applied to a rock, which can cause the rock to change. The three main types of stress go along with the three types of plate boundaries. Compression is common at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries. Q: Compression, tension and shear refer to what type of force that can cause rock to change? Choices: - seismic force - process - gravity - stress A:
A: stress
