Scientists and biologists study the world using experimentation. This can be done through observation, or by performing scientific tests in a lab.
Answer:
Angiosperms
Explanation:
As per the evolution of plants the order is moss (Bryophytes), fern (Pteridophytes), Gymnosperm, and Angiosperm. Bryophytes are the most basic plant with only the capability of photosynthesis. Pterdophytes are an upgrade with being able to transport water and nuterients from the ground into vascular tissue. Gymnosperms and Angiosperms both are seeding plants , but angiosperms use flowers to reproduce.
<span>Archaeas and Bacterias are both Prokaryotes. Both used to be classified in Monera kingdom, but later genetists found that they have actually very different genes, despite they both have a similar metabolism. So they think they have a totally different evolutionary origin and they decided to classify them in 2 different domains. The other domain, Eukarya, includes every other organism (all the ones who are not Prokaryots), which are: plants, animals, fungi and protists.</span>
Proterozoic is the answer.
