Answer:
Length of <em>P</em><em> </em>is greater
Step-by-step explanation:
Length of Oragnism P = 25 nanometer
Length of Organism Q = 2500 picometer
Let's convert both of them to same unit
1 nanometer = 10^(-9) m
1 Picometer = 10 ^ (-12) m
Length of P = 25 × 10^(-9) m
Length of Q = 2500 × 10^(-12)m = 25 × 10 ^(-10)m
Hence
<em>Length of P > Length of Q</em>
