Explanation:
False
Elastic collision is one where two colliding particles both lose some of the kinetic energy. gases tend to have lower densities than solids because gases have lower molar mass. ... if a gas and a liquid are both at the same temperature, the particles of gas have a higher average kinetic energy.
Answer:
Independent variable: Adding/not adding soil.
Dependent variables: Does the plant grow? Amount of leaves, plant length.
Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.
Explanation:
Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.
Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.
Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.

Substances with high pH level are called alkaline.
Alkaline are substances that have a pH greater than 7 and they have a
relatively low concentration of hydrogen ions. This is the opposite of being
acidic leaning towards the other end of the spectrum. Lemons, green vegetables,
root vegetables, garlic, and cayenne pepper are some food that have high
concentrations of alkaline that balance acidity of recipes. It should be
included in one’s diet because it prevents shares of complications that are
taken from high-fat and acid types of food. </span>
