The answer is; The slower the cooling the larger the crystals
Slow cooling allows the aqueous molecules of the compound to find a perfect geometry and grow into a large crystal. Fast cooling causes impurities to be incorporated into the growing lattice hence atagonizing the growing crystals.
I think 1 is C and 2 is A
The most common source of contamination with E.coli is by eating contaminated food like meat and eggs.
There are basically 3 types of pharynx- nasopharynx, oropharynx and laryngopharynx.
The function of the pharynx are:-
1. To transport the food from mouth to esophagus.
2. To warm, moisten and filter the air, before it moves to the trachea, and then to the bronchi, the bronchioles, the alveoli and at last to the lungs.
Therefore, pharynx(or throat) is a part of both- digestive and respiratory systems.
3. It is also important for vocalization.
