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>
1 Distance ( more the distance less will the gravitational pull)
2 mass ( if masses are doubled force will be doubled )
Matter is made up of atoms and has mass. This is because for anything to be considered matter it must contain atoms and atoms must have mass.
Answer:
D) energy from the sun, air, and water
Explanation:
Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.
For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+
. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.
Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.
