It has been proposed that mitochondria and chloroplasts are modern descendants of early prokaryotic cells that began to reside and gradually evolve within primitive cells. which statement supports this view? a) mitochondria and chloroplasts both have prokaryotic ribosomes b) mitochondria and chloroplasts cannot conduct protein synthesis c) prokaryotic cells, mitochondria, and chloroplasts are void of any dna d) mitochondria and chloroplasts are found in all modern prokaryotic cells

The mitochondria and chloroplasts are the modern descendants of the early prokaryotic cells. These resided in the primitive cells and then evolved with them as a part of them. This hypothesis is supported by the fact that both the mitochondria and chloroplasts contain their own primitive ribosomes. Both these organelles have the 70s ribosomes.

Hence, the correct answer is 'option A - mitochondria and chloroplasts both have prokaryotic ribososmes'.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
