Answer:
A - Gain or Lose
Explanation:
Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.
During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.
The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.
For covalent bonding atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
Answer:
Wildfires.
Explanation:
Wildfires is the phenomenon that causes combustion of large forest areas and leads to the release of large amounts of CO2 into the atmosphere.

This wildfires produced high amount of carbondioxide gas in the atmosphere that is the main cause of air pollution.
Answer:
A. Their shape
Explanation:
Receptors (mechanoreceptors) of the sense of balance are located in semicircular canals in the inner ear, which are placed in three planes at an angle of 90 degrees, one in relation to the other. When we move, the liquid in the canals waves and small hairs move from the walls of the canal.
