This is the chemical equation for photosynthesis
6CO2+6H2O--->C6H12O6+6O2
the inputs are the ones on the left:
carbon dioxide used in the calvin cycle and water used in the light-dependent reactions
the outputs are on the right
glucose resulted from the calvin cycle and oxygen resulted from the light dependent reactions
They use energy from the breakdown of a molecule called ATP. ATP is often called the energy currency of our body as it is used all around in the human body for different processes that need energy - so not just active transport of proteins. ATP gets broken down into ADP and an extra group of P (phosphates).
Answer: They evolved from the same line as the cave bear, descending from Ursus abstrusus, a small, primitive black bear. Ursus Euarctos, a black bear, came to North America during the Pliocene Epoch before the brown bear.
Explanation:
it shields humans and other living things from ultraviolet rays
