<h3>What is evolution?</h3>

Evolution refers to the process whereby complex life forms develop from simple life forms or non-living matter as a result of gradual changes over a long period of time.

Evidence for evolution include:

  • Fossil records
  • Anatomy
  • Embryology
  • Biogeography

Similarity in function and structure of anatomical features is known as h0mologous structures.

Hom0logous structures describes the relationship the bones in the forelimbs of penguins and seals as well as the fins of an aquatic worm and the flippers of seals.

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the?
Anvisha [2.4K]

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.

Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.

In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

Consider the observation that serine is the amino acid residue that can be replaced by another amino acid with the least effect
iVinArrow [24]

The question has incorrect option, however the question can be answered by the general explanation. On the basis of the general explanation the answer is as follows:

Answer:

The correct answer is - Serine has a small side chain that can fit in any relatively polar environment.

Explanation:

Serine is an amino acid that have a small side chain in comparison of other amino acid and can be replaced by another amino acid with very least effect on the structure and function of a particular protein as they can fit in any relatively polar environment.

Serine have hydroxyl group in their side chain. It is polar amino acid that can easily establish itself in any polar condition and cause least changes in protein structure and function.

Thus, the correct answer is - Serine has a small side chain that can fit in any relatively polar environment.
