Answer
In most cases when a cockroach dies, it flips on its back, now sometimes to evade predators, it does the same thing and sometimes it may not flip, therefore, to check whether a cockroach is dead or not we need only two characteristic out of seven.
Explanation
As we all know the seven characters of a living being is respiration, movement, excretion, growth, reproduction and sensitivity, now respiration, excretion, growth and reproduction are difficult to witness in a short amount of time therefore we are left with movement and sensitivity, if the cockroach is not moving or playing dead then; the antenna on the cockroach acts upon touch or external stimuli, therefore, the life properties which determine of the cockroach is dead or alive in movement and sensitivity.
