The answer is A.
Prokaryotic organisms are simpler than eukaryotic organisms are are single-celled. They do not contain the genetic information to form complex, specialized structures as eukaryotes do, so they cannot form multi-cellular bodies. The remaining options apply to both prokaryotes and eukaryotes.
Answer:
Resistance = 30 Ω
Explanation:
The resistance of an electric circuit = 
voltage = 24V
current (I) = 0.80A
Therefore, R =
R = 30 ohms
