The correct statement about hydrochloric acid and acetic acid is : ( A )
The pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.
Given that pH is the inverse of concentration of H₃O⁺ ions , The stronger acid ( Hydrochloric acid ) dissociates in solution producing a maximum amount of H₃O⁺ ion, while the weak acid ( acetic ) will disassociate partially in a solution producing a lesser amount of H₃O⁺ ion.
Therefore the pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.

I cook for my family every day, on my way back home, I phone my family to see what kind of food is in the fridge, so I can go shopping in the market.

Once home I chop the vegetable and cook the pasta, and we sit down for dinner.
Answer: 1,2 and 3.
The following are common to transformation, transduction and conjugation.
1. Unidirectional transfer of genes.
2. Incomplete gene transfer.
3. Homologous recombination.
Explanation:
Transformation is the taking up of free DNA from the environment.
Transduction is the transfer of DNA by bacteria to a viruses.
Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional .
