Suppose that a gene originally identified in nematodes (roundworms) is found to be homologous with a gene that can cause developmental abnormalities in humans. Would it be possible to study this same gene in fruit flies? Explain.

That statement point out that the gene is homologous. Homologous gene are evolved from common ancestor.So this gene can found in the ancestral population of both protostomes and deuterostomes.

Explanation:

Evolutionary relationship of three animal species (human,nematode and fruit fly) are closely related.The gene sequence of human and fruits fly are closely related than nematodes.There are 100 common genes among these three species.so it is possible to genetic study among them..

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.
