Answer:
Protons and neutrons have similar mass.
Electrons are smaller than a proton or a neutron.
Explanation:
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons
I think this is actually a physics question-
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.
Hope this helps :)
Correct Answer: B. Catch B
Explanation: Fish depend on dissolved oxygen to survive. Ponds with high levels of dissolved oxygen will support more fish (and larger fish) than ponds with low levels of dissolved oxygen. Trout are particularly sensitive to dissolved oxygen levels, so a pond with a healthy trout population probably has high levels of dissolved oxygen.

A population would be an organism (the same species) living in an area
Answer:
An increase in the amount of greenhouse gases in the atmosphere
Liquid; gas
Lacking oxygen
To decrease the temperature in the compost pile
Explanation:
1. Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.
2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.
3. Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.
4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
