G Pernicious anemia is caused by impaired absorption of vitamin B12. What is the effect of this impairment on the catabolism of amino acids? Complete catabolism of phenylalanine is blocked by the inability to convert phenylalanine to tyrosine. Complete catabolism of methionine, threonine, isoleucine, and valine is blocked by inability to degrade propionyl‑CoA. Complete catabolism of valine, isoleucine, and leucine is blocked by the inability to oxidize branched chain α‑keto acids. Complete catabolism of phenylalanine is blocked by the inability to degrade homogentisate. What metabolite or metabolites appear in the urine as a result of pernicious anemia? branched chain keto acids phenylpyruvate homogentisate methylmalonic acid

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

the correct answer is:

a population changes in response to a change in the environment.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
