5) The process of natural selection favors certain characteristics in organisms, while it selects against other characteristios. What would happen if there was zero variation between all of the organisms on Earth?

If there was zero variation between all organisms on Earth, natural selection would have no role to play. Without variation, there would be no differences in traits for natural selection to act on. This would likely lead to a lack of adaptation to changing environments, making organisms more vulnerable to extinction. Additionally, with no variation, there would be no diversity in species, leading to a less resilient and less complex ecosystem. In essence, zero variation would disrupt the balance of nature and potentially lead to the decline of many species.
