Answer the following question given this paragraph: When the ore leaves the mine, it is not yet a useful material ( Figure below ). Most ores are a combination of metal and other elements. The rocks are full of valuable minerals. They also contain rock that isn't valuable, which is called waste rock. The valuable minerals must be separated from the waste rock. Q: Along with other elements, most ores are made of what? A:

OPTIONS:
- coal
- crystals
- sodium
- metal

Answer: metal

Problem: OPTIONS:
- viscosity and gravity
- momentum and density
- depth and decrease
- depth and density
Q: Answer the following question given this paragraph: Two factors that affect the pressure of fluids are depth and density. This explains why water pressure is greater deeper in the ocean and air pressure is greatest at sea level. Denser fluids, such as water, exert more pressure than less dense fluids, such as air. Q: What are the two factors that affect the pressure of fluids? A:
Answer: depth and density

Problem:OPTIONS:
- mass
- gravity
- absorption
- wavelength

Answer the following question given this paragraph: a) The water forms the bottom of the tube and thus where the node of the wave will be. Thus the air column is where the sound wave can exist. The larger the air column, the larger the wavelength. Frequency is inversely proportional to wavelength, thus the tube with the smallest air column will have the highest frequency. So the answer is tube C. Q: In frequency, the larger the air column, the larger the what? A:
****
A: wavelength

Answer the following question given this paragraph: CHAPTER SUMMARY 5.1 Overview of Photosynthesis The process of photosynthesis transformed life on earth. By harnessing energy from the sun, photosynthesis allowed living things to access enormous amounts of energy. Because of photosynthesis, living things gained access to sufficient energy, allowing them to evolve new structures and achieve the biodiversity that is evident today. Only certain organisms, called autotrophs, can perform photosynthesis; they require the presence of chlorophyll, a specialized pigment that can absorb light and convert light energy into chemical energy. Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules (usually glucose) and releases oxygen into the air. Eukaryotic autotrophs, such as plants and algae, have organelles called chloroplasts in which photosynthesis takes place. Q: What are the only organisms that can perform photosynthesis? A:
OPTIONS:
- sponges
- monocots
- heterotrophs
- autotrophs
autotrophs
