Answer: I think the answer is B. measure one side with a ruler, and multiply that number by itself three times.
Explanation:
Answer;
-Measure one side with a ruler, and then cube it, or in other words multiply that number by itself and then by itself again.
Explanation;
-Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains.
- Volume is measured in cubic units, such as the cubic meters, cubic centimeters. The SI units of volume is cubic meters.
A cube has all edges (sides) of the same length. The volume of a cube is found by multiplying the length of any edge by itself twice.

Desertification is when an environment becomes drier, like a desert.The Dry climate causes plant life to decrease, which causes pray life to decrease, which causes predators life to decrease. This significant change is vary harmful to the environment. This can happen to any environment. Deserts expand when this happens to deserts.
B. The enthalpy of the reaction doubles.
C. The sign of the enthalpy of the reaction reverses.
D. The enthalpy of the reaction is halved.
Answer: C. The sign of the enthalpy of the reaction reverses.
Explanation: Enthalpy of a reaction is the net heat absorbed or released during a chemical reaction.It is represented by . It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.
When a chemical reaction is reversed the heat of the reaction changes its sign.
The decomposition of calcium carbonate is an endothermic reaction as heat is required to break the bonds and thus energy is absorbed.
When the reaction is reversed, the reaction becomes exothermic as now bonds are getting formed and energy is released.

Arabic is the most commonly spoken language in the Sahara.
The Sahara is an African desert that is inhabited by several people (about 2.5 million) from different origin and with different languages. Arabic is the most commonly spoken language in the Sahara.

The Sahara contains 11 countries which include Sudan, Morocco, Niger, Chad, Mali and Libya and it is very large with a land area of about 9,400,000 square kilometers.
Answer:
4) The neuron receives a stimulus great enough to start an impulse.
5) Gated Na+ channels open. The net movement of Na+ ions into the cell produces the action potential..
2) Na+ gates close and K+ ions flow back out of the cell restoring the resting potential.
1) The impulse continues to travel down the axon away from the cell body.
3) Gated K+ and Na+ channels are closed. The inside of the cell is slightly negative compared to the outside.
