Answer:

Nitrogen

Explanation:

Adenine is one of the four nitrogenous bases while Ribose is one of the two sugars (carbohydrates) that make up a nucleotide. Adenine is structurally composed of 5 carbon atoms, 5 hydrogen atoms and 5 nitrogen atoms to form the chemical formula C5H5N5 whereas ribose is structurally composed of five carbon atoms, ten hydrogen atoms, and five oxygen atoms to form the chemical formula; C5H10O5.

Based on the above explanation, it is evident that the element present in Adenine but not in Ribose is NITROGEN. Nitrogen is a major constituent of all nitrogenous bases (Adenine, Guanine, Cytosine and Thymine (Uracil).

Answer:

The options

a. sympatric speciation; vicariance

b. allopatric speciation; vicariance

c. sympatric speciation; dispersal

d. allopatric speciation; dispersal

The CORRECT ANSWER IS d.

d. allopatric speciation; dispersal

Explanation:

Allopatric speciation takes place either via dispersal, when some members of a species shifts it's habitat to a separate geographical area which leads to differentiation of the initial group into separate diverse varieties or species(as in our case study).

Allopatric speciation through dispersal could results in multiple speciation leading to an individual original species producing diverse new species; this occurrence is called adaptive radiation.

In some scenario, a population of an individual species disperses all over a region with each locating a separate niche or isolated habitat. In the course of time, the diverse demands of their just formed lifestyles causes multiple speciation events that comes from a singular species.
