Answer:
The gravitational pull of the moon and the rotational force of the Earth cause tides to rise and fall across the planet. The species living in coastal areas most affected by changing tides have unique ways of surviving.
So, the answer is B.
The buoyant force is the upward force or thrust...Simply, consider immersing your hand into a bucket of water. What happens to it? It raises (a little). The raising is due to the buoyant force. Basically it is the upward force/thrust that acts on any object immersed into a fluid. Hence why things float when out in water. Hope this helped!!

two potassium and one oxygen
Explanation:
Oxidation number of K = +1
Oxidation number of O = -2
- During the formation of a compound the elements exchange their combining powers.
- The combining power corresponds to the number of electrons usually gained or lost or shared by atoms of elements during a chemical combination.
- It is also the number of negative and positive charges carried by ions.
This combining power corresponds with the oxidation number given:
K O
Combining power 1 2
Exchange of valencies 2 1
Molecular formula of the compound is K₂O
This shows two atoms of potassium and one atom of oxygen.
