Consider the cladogram representing most of the major categories of animals. what physical characteristic is used to divide the animals into the two main clades?

Kingdom Animalia is divided into seven phyla.  Phylum Chordata includes vertebrates (animals with spinal columns and spinal cords).  The other six phyla are made up of invertebrates (animals without spinal columns and spinal cords).  The presence or absence of a spine is the physical characteristic that is used to divide animals into two main clades.

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.

its temperature is increasing. this causes molecular vibrations to increase.
