Snail is found to be attracted towards some leaves such as coriander leaves, Manasi from Mumbai is trying to study behavior of snails using coriander leaves.
When coriander leaves are kept in-front of snail, it moves towards them to eat it.
Now Manasi is designing an experiment where she mixes quinine (a bitter tasting chemical) with coriander leaves and keeps infront of Snail.
The snail initially gets attracted to the leaves, and tastes it. But as it tastes it finds the taste of it very bitter and unlikable and withdraws its tentacles and body away from coriander leaves mixed with quinine.
Manasi is asking a question, how long snail will have the memory of this bitter experience?
How long the snail will keep moving away from even a normal coriander leaves without any quinine.
Manasi is planning experiment to check memory in snails.
Please help Manasi by providing suggestions here on how could she design the experiment to test memory in snails?
