Answer:
Heat
Explanation:
Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.
Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. This explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. These prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast.
Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.
