Answer:
12.5m/s^2
Explanation:
Acceleration of an object can be calculated by using the formula;
a = v-u/t
Where; a= acceleration
v= final speed
u= initial speed
t= time
According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.
Since time is 12s, the acceleration is thus:
a = 150-0/12
a= 150/12
a= 12.5
Hence, the acceleration of the flying object is 12.5m/s^2

Explanation:
Earthworms, frog and squid have different respiratory systems in that such evolutionary features are in accord with their thriving environment. They differ basically in the adaptive makeup of these morphological features. For instance, frogs have lungs, squid have siphons and earthworms through their skin.
