<span>Early life was too simple to fully fix the sun or use higher functions to provide it's own energy. They were probably more like archaea that are seen around vents in extreme regions, such as the floor of the ocean or in high temperature pools in Yellowstone. These items "eat" the sulfur and other energy to create their needs. This would develop by necessity into mitochondria and chloroplast like bacteria as they ventured out from the vents to other areas and competed for heat and energy</span>

5. Describe: How did Earth's oceans form?
UNO [17]

The earth began as a cloud of dust and hot, shining gas. When our planet began to cool, its surface solidified, surrounded by clouds of water vapour. When this vapour condensed (changed into liquid) and began to fall like rain, seas, and oceans formed in the hollows of the Earth’s surface. Oceans are huge expanses of water which separate the Earth’s continents. The largest ocean is the Pacific Ocean, second, the Atlantic and third largest, the Indian Ocean. Seas are smaller expanses of water, almost always flowing either into oceans or other sea. The waters of the seas and the oceans are always salty, because they are rich in mineral salts and especially sodium chloride, which is the salt used in cooking.

Do Seedless vascular plants use spores to reproduce?
Neporo4naja [7]

Answer:

In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.
