The genetic code is considered universal because the same four nucleotide bases are used by all known organisms
Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge. In allopatric speciation, groups from an ancestral population evolve into separate species due to a period of geographical separation.
The isolation barriers prevents two of the species to mate, resulting in them evolving into different species
There are choices for this question namely:
A. A second more extensive rise in glucose.
B. An overwhelmed insulin-adjusting mechanism.
C. A distention of the duodenum from an excessive amount of chyme.
<span>D. An overproduction of insulin that occurs in response to the rise in blood glucose
Dumping syndrome is an unsynchronized mechanism wherein there is a higher than normal rise of insulin levels causing transient but severe hypoglycemia. This typically presents within 1 and a half hour after eating wherein there is a physiological transient hypoglycemia but then overwhelmed by the non-synchrony of insulin effects causing severe hyperglycemia. Therefore the correct answer is "a</span>n overwhelmed insulin-adjusting mechanism." The choice "an overproduction of insulin that occurs in response to the rise in blood glucose" is wrong because an overproduction of insulin will result to lower blood glucose.
