The diagram represents a taxonomic tree showing the possible evolution of six species of finches. The most likely explanation for the branching pattern seen in the circled region labeled X is that:
A.
environmental changes resulted in extinction
B.
speciation occurred as a result of inbreeding
C.
no speciation occurred during this time
D.
environmental changes influenced speciation

Option B

Explanation:

As we can see in the figure,  three species of the finches in circle lie on the same main branch as three sub branches. This is an example of speciation caused by interbreeding of species which led to removal  of deleterious genes and then caused emergence of three species adaptable to the existing environmental conditions.

Hence, option B is correct

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
