It is unlikely that gene duplication events in the hox complex played a role in the adaptive radiation of animals. a) the new gene copies led to lower metabolic rates. b) the new gene copies facilitate the evolution of more complex body plans. c) the new gene copies facilitate the evolution of smaller bodies.

C & A

Explanation:

The HOX genes encodes important transcription factors. This factors causes protein to be made that specify cell fate and identify; embryonic primary axis, secondary axis and plays important roles in various tracts development.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
