18.     based on this image, what can be inferred about the organization of life?  
            a.  there are only two organisms within one population.    b.  bigger systems build on smaller systems.    c.  there are no connections among organisms.    d.  smaller systems build on larger systems. 
   

Answer choice B

Explanation:

As you move clockwise in the systems, each picture shows that the bigger systems come from and build off of the smaller systems

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
