Explain how organisms came to live on land and how?

Life on Earth evolved in oceans, while the land was not suitable for living due to lack of ozone and oxygen. With time, photosynthesis enriched our atmosphere with oxygen and the ozone layer was formed. This allowed the ocean-based life forms to evolve and venture onto land. From skeleton-less soft bodies, animals evolved lighter bodies with slim, strong legs to carry them against gravity. They had hard exoskeletons to protect them against weather elements such as rain,...

Explanation:

the correct answer is b, "fertility rates are increasing, so populations will grow more quickly in the future."

that could be the way we reach some of these scientific feats that we all seem to want. we could connect to many other things. that could be the way we connect to extra-terrestrial, and even spirits of the dead.

dreaming is something that humans take for ranted, when really, it could be the key to the universe.
