Lynn Margulis developed the endosymbiont theory to explain the evolution of certain eukaryotic organelles, such as chloroplasts and mitochondria. According to this theory, which of these events occurred to an ancient prokaryotic cell?

Endosymbiosis theory suggests that eukaryotic cells emerge from prokaryotic cells.

Explanation:

Biologist Lynn Margulis was the first person who studied the endosymbiosis in 1960. According to him the chloroplasts and mitochondria have been originated from ancient bacteria which was free living. These organelles are found in eukaryotic cells. The chloroplasts are found in plant cells and they have a green pigment called as chlorophyll which helps in the process of photosynthesis by absorbing the sunlight energy. The mitochondria produce energy in the form of ATP by the biochemical oxidation of the food.

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.

answer; both surfaces of the membrane are nonpermeable
