Question

A tiger develops lockjaw and can no longer open its mouth. Which of the four life functions will not be able to perform? (it obviously cannot eat. This question is asking for one of the four functions that we used to define life.)

Answer 1

I believe the answer is: It won't be able to eat.

In wild life, this type of condition is basically a death sentence for the organism who experience it. The only way for the tiger to survive in such situation is only if humans making an intervention by surgically fix them or find another pathways to injects the nutrition into the tiger's body.
