The answer D. guanine (G)
Answer:
Electric current is the flow of electrons and they carry negative charge so electrons inside an atom repels the flow where as a proton attracts the flow.
Explanation:
- Electricity is the process of flow of electrons. During the flow these electrons share bonds or even transfer them.
- These electrons get energy when the potential difference is applied to a conductor that is moving in the direction from low to high therefore, the electrons move from one to another creating electricity.
- Though the electron repels the continuous flow but proton develops the force of attraction.
Evaporation happens when a liquid substance becomes a gas. When water is heated, evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Once water evaporates, it also helps form clouds.

<span>What is the difference between calories and kilocalories? The "calorie" we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (upper case C). A kilocalorie is the amount of heat required to raise the temperature of 1 kilogram of water one degree Celsius.</span>
