Because freezing will often burst the cell walls and destroy tissue. The crystals of ice are very sharp and hard to control AFAIK. Note what happens to a banana or many types of fruit after you dethaw — it becomes all mushy and not of the same structure, fiber and cell form as before, like a bad beam up in Star Trek.
Well, it depends on the type of hippo.
A common hippo would live in a grassland or savanna kind of place in Africa.
Pygmy Hippos, though, live in Tropical Rainforests.
The ducts empty the saliva from the submandibular salivary glands into the two sublingual carnicles.
The saliva produces in the salivary glands contains an enzyme named amylase, which is responsible for the chemical breakdown of starch. The saliva also helps to add moisture to the food and make it easier for it to pass through the ailementary canal. Further break down of starch then occurs when amylase is secreted into the small intestines.

I have no straight answer with ABDE as of your lack there-of. But here.
Gene flow is the introduction of genes/alleles between populations. An example is a flower having it´s pollen carried by a bee. The bee then introduces it (intentional or not.) to other flowers.
Another example is a pack of gray wolves suddenly having a different wolf introduced. *As long as it can breed, that is* They will slowly incorporate the new alleles/genes into the pack.
I wish you luck young lad.
