Answer 1

556

Explanation:

So, 378/189=2. So it will double two times. x2x2=x4. 139x4=556.

Answer 2

556

Explanation:

There's an initial population of 139 bacteria in a colony. If it doubles every 189 minutes, then the population would be 556 in 378 minutes from now.

189th minute= 139+139=278

Since 189+189= 378, Just double 278 again, which gives you 556.
