Question

How can we differentiate so many different foods if we can only taste four flavours on our tongue: sweet, bitter, sour, and salty?​

If the taste is sour then it is acid.

If the taste is bitter then it is base.

And if u feel slippery then it is neutral like soap..etc.

Answer 2

Answer:

Those are called papillae (say: puh-PILL-ee), and most of them contain taste buds. Taste buds have very sensitive microscopic hairs called microvilli (say: mye-kro-VILL-eye). Those tiny hairs send messages to the brain about how something tastes, so you know if it's sweet, sour, bitter, or salty.
