Explanation:
Living organisms obtain energy for cell processes from plants.
Energy for all life begins from the process of photosynthesis in plants.
Green plants manufacture food in the presence of sunlight combining carbon dioxide and water to produce glucose and oxygen gas.
- The glucose in plant stores chemical energy.
- When animals eat plant matter directly or indirectly, they release energy from the glucose.
- This is how living organisms obtains energy for cell processes.

Answer: Option 1, 4 and 5 describe acids accurately.
Explanation:
Option 1: Acids have a sour taste because of the concentration of 
ion.
Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as 
is a strong acid which can burn skin as well as fabric.
Option 3: Acids need electrons to release ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.
Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce ions.
Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
What is the resistance to motion
Answer:
D. Moles of solute (mol) ÷ liters of solution (L)
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in 1.0 L of the solution.
M = (no. of moles)solute / (V of the solution (L))
<em>So, the right choice is: D. Moles of solute (mol) ÷ liters of solution (L)</em>
