Q: What occurs between long warm climate periods? Choices: - hurricanes - mass extinction - drought - ice ages A:
ice ages
Answer the following question given this paragraph: Q: During metamorphosis, most salamander species go through what aquatic stage on the way to becoming adults? Choices: - prophase - metaphase - anaphase - larval stage A:
larval stage
Q: Answer the following question given this paragraph: Competition is a relationship between organisms that depend on the same resources. Competition can occur between members of the same species or between members of different species. Q: What can be calculated by solving the average speed formula? Choices: - accelaration - distance or mass - mass or time - distance or time A:
A: distance or time
Question: Answer the following question given this paragraph: An important way of making ATP without oxygen is called fermentation . It involves glycolysis, but not the other two stages of aerobic respiration. Many bacteria and yeasts carry out fermentation. People use these organisms to make yogurt, bread, wine, and biofuels. Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration. Q: What is the process of making atp without oxygen called? Choices: - condensation - photosynthesis - Cell Division - fermentation A:
Answer: fermentation

Answer the following question given this paragraph: A hot-water heating system uses thermal energy to heat water and then pumps the hot water throughout the building in a system of pipes and radiators. You can see a diagram of this type of heating system in Figure below . Typically, the water is heated in a boiler that burns natural gas or heating oil. There is usually a radiator in each room that gets warm when the hot water flows through it. The radiator transfers thermal energy to the air around it by conduction and radiation. The warm air then circulates throughout the room in convection currents. The hot water cools as it flows through the system and transfers its thermal energy. When it finally returns to the boiler, it is heated again and the cycle repeats. Q: A hot-water heating system uses what type of energy to heat water? Choices: - negative energy - potential energy - atmospheric energy - thermal energy A:
**Answer**
thermal energy
