Approximately 2 million years ago the genus Australopithecus gave rise to a new genus, Homo. Today, we retain the genus as Homo
nydimaria [60]
There was two of the same question, but here is the answer again with a little more depth.

D - spine alignment and foot size.

It was only the late Australopiths that had an S-shaped spine. This allowed for them to be bipedal, that is, the ability to walk on two legs as we do. This is because the S-shaped spine allowed them to balance when they were standing. The late Australopiths also have shorter and less flexible toes. These smaller, but sturdier feet made pushing off the ground much easier - aiding in their bipedalism.

Answer:

  • Blood sugar regulation in a diabetic patient is done by
  1. Injecting prescribed quantity of hormone insulin after definite time intervals.
  2. Consuming prescribed amount of sugars.
  3. Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.

Explanation:

  • The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
  • When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
  • When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
  • In a diabetic patient, usually the beta cells of the pancreas are affected  but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
  • But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.
