Answer:
The correct answer is : prokaryotic organisms like E. coli and higher organisms share common ancestor.
Explanation:
E. Coli is a prokaryotic organism or bacteria. On the metabolic level these organisms share similar homology with the higher organism other than this these organisms also show same core functions with higher level organisms such as elephant.
These similarities suggest that the all the living organisms share a common ancestor. The french scientist Jacques Monod statement "Anything found to be true of E. Coli must also be true of elephants." is also based on this notion.
Answer:
. Identify the process that triggers the initial surge of nitrogen excretion,
The reason for this is because of the gluconeogenesis ,(in the liver and cortex of the kidney) which make up for the reduction in glucose blood level, from rapid catabolism to glucose at the beginning of fasting, by breaking down protein to glucose in the liver. Therefore excess Nitrogen is produced as the byproducts of amino acids catabolism.
Physiologically the mammalian brain prefers the keto bodies supply from fatty acids catabolism from gluconeogenesis compare to protein. These water solube subtances cross the BBB to reach the brain the CNS substituting for glucose. Thus as more fatty acids is converted to ketobodies at faster rate, the brain gets adapted to this, and therefore catabolism of amino acids drops, hence Nitrogen concentration in the blood drops.
However, with exhaustion of Glycogen and fatty acid, catabolims of amino acids resumes. therefore, more amino acids are broken down, and Nitrogen build up in the Urine for excretion.
