Question

which sequence represents the correct order of events for the production of necessary complex molecules after food is taken in by a multicellular animal? 1 diffusion → synthesis → absorption → digestion → circulation 2 circulation → diffusion → synthesis → absorption → digestion 3 digestion → absorption → circulation → diffusion → synthesis 4 synthesis → digestion → absorption → diffusion → circulation

Explanation:

First, food is broken down by digestion. Then the nutrients are absorbed into the bloodstream. The blood circulates to transport these nutrients. Nutrients diffuse into cells, and finally, synthesis of necessary complex molecules occurs using these nutrients.

Answer:

C. digestion → absorption → circulation → diffusion → synthesis
