Mitosis is responsible for growth, repair, and maintenance in an organism because A. it occurs at a faster rate than meiosis
B. The chromosomes number is reduced by half
C. exact duplicates of each mother cell are produced
D. it is the only process involves replication of genetic material

Mitosis is responsible for growth, repair and maintenance of an organism because it produces all the daughter cells that are genetically identical to one other and therefore creates new available cells that are specific to each tissue for growth and repair.

Hope this helps! Please correct me if I'm wrong!

not sure if this is what you'r looking for eubacteria and archaebacteria

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.
