Answer:
The correct option is: A) sympatric speciation
Explanation:
Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the existing common descent. The new species and the ancestral species all live in the same geographic area or location.
The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.
Answer:
osmolarity depends upon molarity.
glucose is a non-ionizing substance. it won't break down and will go as a whole.
osmolarity means the solute concentration of a solution.
here, the solvent is water.
therefore, 1 osmole = 1 mol
the ions of glucose after forming a solution (i) = 1
osmolarity = 1.5 M glucose × 1
= 1.5 osmoles of glucose.
