Answer:
Chloroplast is crucial for photosynthesis not mitochondria...
Explanation:
Chloroplast isn't found in animal cells not because of it's evolutionary choice but because of it's rather different way of energy production. Chloroplast is modified by nature to produce energy using photons or photosynthesis that can only occur in plants but mitochondria does not used photons. It utilizes electron transport chain strategy instead.
Animals would never be able to make their surfaces photosensitive for photosynthesis to occur and produce energy with the help of chloroplasts.
Answer:
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
Explanation:
It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
I believe all living things can be found in the Biosphere.
