There are four postulates of Darwin in which individual of species are not identical, traits are eased from one generation to the other and more offspring are born than that can survive. survivor of the competition for resources will reproduce only.
The four principle or postulates of Darwin are - variation , inheritance , selection and time. these all are considered the evolutionary component natural selection mechanism.
One is origin species by means of naturally selective mechanism, then preserve in the struggle of race of life.Darwin selection is mainly depends on the environment and heritable variations.All species of organisms which arise through natural selection of survive and reproduce.

Answer:
Something called side groups
Explanation:
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called "R" groups, interact with the environment.
1) Producing more offspring at a time
2)Reproducing more often
3)Reproducing earlier in life
Destruction of the pancreatic "Beta Cells" can lead to hyperglycemia is enough of them are annihilated. This is because the beta cells of the organ the pancreas are responsible for producing the hormone insulin, whose job is to lower blood-glucose levels when they rise (as after a high-carbohydrate meal).
Without enough insulin secreted by beta cells, glucose levels will continue to rise in the blood plasma, a condition called hyperglycemia.
This is actually the main cause of insulin-dependent diabetes mellitus (IDDM, aka Type 1 Diabetes).
