For any galvanic cell to operate at standard conditions, a) ΔG° and ΔE° are both positive
b) ΔG° and ΔE° are both negative
c) ΔG° is positive and ΔE° is negative
d) ΔG° is negative and ΔE° is positive

ΔG° is negative and ΔE° is positive

Explanation:

A galvanic cell produces electrical energy from spontaneous electrochemical processes.

In a galvanic cell, ∆E° is always positive since the reaction is spontaneous at room temperature.

Generally in thermodynamics, a negative value of ∆G shows a spontaneous chemical process. Hence in a galvanic cell, ΔG° is negative and ΔE° is positive.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
