The correct option is this: THE ORGANISM IS A PROKARYOTES.
There are basically two types of cells, prokaryotic and eukaryotic cells. The prokaryotic cells are primitive cells which contain only a few materials which are not well organised. This type of cells is usually found in microscopic organisms. The cells lack organised nucleus and cell organelles which have membranes.<span />

Answer:
Molar concentration of HCl = 0.279 M
Explanation:
Given data:
Volume of NaOH = 31.00 mL ( 31/1000 = 0.031 L)
Molarity of NaOH = 0.0900 M
Volume of HCl = 10.00 mL (0.01 L)
Molar concentration of HCl = ?
Solution:
Chemical equation:
NaOH + HCl → NaCl + H₂O
Number of moles of NaOH:
Number of moles = Molarity × volume in L
Number of moles = 0.0900 mol/L × 0.031 L
Number of moles = 0.00279 mol
For one mole of HCl one mole of NaOH is required.
Number of moles of HCl = 0.00279 mol
Molar concentration of HCl = 0.00279 mol / 0.01 L
Molar concentration of HCl = 0.279 M
Answer: Equilibrium
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction which means the products are being made as quickly as reactants
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
