Answer:
When animal cells are hypotonic means, the cell has absorbed too much water through the membrane. Therefore, the osmotic pressure is very high. Consequently,they deform and could eventually burst.
They all have pollen in the center which makes them duplicate and make more of their species of flower
The crayfish have its nerve cord on the ventral side rather than on the dorsal side. The ventral side is under the Crayfishes' exoskeleton, as opposed to the dorsal side where the exoskeleton is . If it is attacked it will be from the dorsal side and the nerve cord would be snapped easier. The function of the nerve cord is that if it gets attacked by a predator they will go for the top and it will still be able to move.
