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>
Yeah yeah so :D,
Large polar molecules can only cross the membrane with the help of protein named channel protein and carrier protein.
So, this both proteins act like a gate, the large molecules enter the protein and the protein let the large molecules in to the membrane. (see the picture so that you can understand more, its carrier protein)
the only difference between channel protein and carrier protein is, channel proteins has fixed shape while carrier protein can flip.
That would be cellular respiration.
Answer:
The products of aerobic cellular respiration are <u>CO2</u>, <u>H20 (Water Vapour)</u>, and <u>Energy</u>.
C6H1206 + O2 ➔ CO2 + H20 + Energy
Glucose + Oxygen ➔ Carbon Dioxide + Water Vapour + Energy
