sergeinik [125]

Answer:

The professor Bonefinder has made a mistake.

Explanation:

I't is true the Hominoid had a long snout, a large orbits that are partially enclosed, but they have no tail. This point is really critical because the morphology of an species is really important. The taxonomists use the information that morphology gave for many years to identify species, nowadays with molecular techniques some of those species are pulled apart, but the important matter is that hominoids had no tail.

So the professor Bonefinder analysis is incorrect because the hominoids have no tail.

The correct sequence for aerobic metabolic breakdown of glucose is
Luba_88 [7]

Answer:

a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system

Explanation:

  • Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
  • In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
  • The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
  • The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
