Young cultures must be used when doing a gram stain to get more accurate results. The cell was is the part of the bacterial cell that is most involved with gram staining because it holds the crystal violet.
Why must young cultures be used when doing a Gram stain Young cultures must be used so the crystal violet can stick to the cell walls of Gram positive bacteria. The cell walls break down in old cultures and the staining process is not accurate
Bacteria should be around 24 hours old to properly interpret Gram staining results. Younger cultures may not have developed mature cell walls, affecting the staining pattern observed. Older cultures may display autolysis, altering cell morphology.

No. For any staining it must be dry and not too cold.

All samples must be under 24 hours old or you might get an incorrect reading.
Platypuses are not particularly playful, and they do not play with their young. Females are excellent mothers, and they nurture their young carefully, doing what they can to protect them. They must leave the young in a chamber at the end of a burrow when they go out hunting for food in the creeks and rivers alongside of which they live. They teach their young to dive and hunt for food, but they do not play with them.
there can be existence of different cultures (sub-cultures) in an organization. but there must be a main culture of the organization. if there are more than one strong main cultures in an organization, there must be cultural & value conflict.
we must shake it because crystals of crystal violt preceptiate in the bottle
