Answer 2

Answer:

Explanation:

Sticky frog saliva is a non-Newtonian fluid. ... This unusual combination of tongue and saliva allows a frog to catch insects, mice or even small birds faster than you can blink — five times faster, in fact. Once captured, the prey is yanked back toward the frog's mouth at a force up to 12 times greater than gravity.
