Explanation:
This is what I found hopefully it helps :)
Following glycolysis, the mechanism of cellular respiration involves another multi-step process—the Krebs cycle, which is also called the citric acid cycle or the tricarboxylic acid cycle. The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH2), as well as some ATP.
The correct answer is C. The three germ layers.
The feature which is only shows higher invertebrates as compared to lower invertebrates is referred to s the three germ layers.
Germ layers is termed as the primary layer of cells which forms during embryogenesis. Three germ layers which are invertebrates are pronounced as eumetazoans which includes animals.
An example of an animal which produces two germ layers is Cnidarian which are endoderm and ectoderm and makes them diploblastic.
Chordates produce third layer which is mesoderm and makes triploblastic. Germ layers they give rise to all animals organs and tissues under process known as organogenesis.
