What does the tree of life represent? (1 point)

a. the current hypothesis of the evolutionary relationships between organisms
b. the relationship between different taxa in the three domains based on dna evidence
c. the linnaean relationships between kingdom, phylum, class, order, family, genus, and species
d. only the clades that include living organisms

Correct A). The current hypothesis of the evolutionary relationships between organisms

The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.

Hence, the correct answer would be option A.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
