The results will most likely be valid because the scientists kept getting the same results after REPEATED experiments. If they just conducted one experiment then they would not have been sure if what happened was a fluke or if another thing would happen after another experiment.<span />
It would be D. Water molecules are split apart and the byproduct of that would be the O2. As energy enters the chloroplasts, the energy excited the H2O molecules and causes them to split
There appears to still be a lot of debate within science over whether humans or climate change were primarily responsible for the extinction of many of the large mammals during this period. One hypothesis supporting the link to early human hunters is that large animals in sub-Saharan Africa co-evolved with humans as they learned how to use tools and developed ever more effective weapons. When early humans moved into Europe and Asia, taking with them their weapons and hunting skills, the populations of large animals in those areas were not accustomed to human hunting, and were therefore easy prey.
