Answer
The reason for taking the melted agar deeps out of the water one at a time and using them immediately is to maintain the agar in a liquid state and prevent premature solidification.
Solution
a
Temperature Control: Agar solidifies at around 40-45°C. By keeping the agar deeps in hot water, we ensure they remain in a liquid state until they are ready to be used
b
Sterility: Taking the agar deeps out one at a time minimizes the risk of contamination, as each deep is exposed to the environment for a shorter period
Key Concept
Maintaining agar in a liquid state
Explanation
Agar needs to be in a liquid state to be poured and used effectively. If it solidifies prematurely, it cannot be used for its intended purpose, such as pouring into Petri dishes or tubes.
