Answer:
Ions are atoms with a positive or negative charge.
Explanation:
Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.
The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.
The other options are not correct because of:
- <em>There are usually as many or more neutrons than protons.
</em>
- <em>Uncharged atoms are neutral.
</em>
- <em>The number of protons or neutrons does not affect the electric charge of the atom.</em>
- <em>Atoms that joined in fixed proportions can form molecules.</em>
Answer:
Mainly water
Explanation:
The main function of a plant's vacuole is to provide pressure to give structure to the cell itself. As for central vacuoles, they fill up and store water which pushes against the cell wall.
Hopefully this made sense
returns freshwater to the earth
occurs after condensation
is roughly equal to the amount of evaporation
Explanation:
Precipitation returns fresh water to the earth, occurs after condensation and is roughly equal to the amount of evaporation.
The process of precipitation is a key component of the hydrologic cycle.
- In the hydrologic cycle, precipitation follows condensation of water vapor in the atmosphere.
- Precipitation often takes the form of rainfall and snow.
- It is any product of condensation of water in the atmosphere that falls back under the influence of gravity.
- In the hydrologic cycle, water leaves the surface of the earth in form of vapor as result of evaporation.
- Most times , the amount of evaporation is roughly equal to that of precipitation.
