From about 450 to 300 million years ago, bryophytes dominated the earth's vegetation, and then about 300 million years ago, gymnosperms began to become more prominent.
<h3>Evolution of plants</h3>
About 450 to 300 million years ago, most of the plants as we currently have them are yet to evolve according to evolutionists.
Instead, seedless vascular plants such as bryophytes were around. Many years after, these seedless plants evolved into vascular plants with seeds that are not enclosed in fruits.
Vascular plants with seeds but without fruits are known as gymnosperms. Plants whose seeds are enclosed in fruits, angiosperms, evolved thereafter.

The answer is B, DNA to RNA to protein
Answer:
they have genetic materials all in common
Explanation:
oh also i forgot DNA also works
Answer: d. classification schemes for prokaryotes
Explanation:
Bergey’s manual of systematic bacteriology is the main resource for identifying the prokaryotic organisms, the main emphasis is over the bacterial species. This manual uses every characterizing aspect for classifying the organisms specially the bacteria. It is includes the classifying schemes to identify all unknown prokaryotes.
It was published by David Hendrick Bergey 1923 which describes the functional and structural features for arranging and classifying the organisms in the specific familial orders.
True
Crossing over involves homologous chromosome pairs "crossing over" and exchanging genetic information.
I have attached an image that might help you understand the concept a bit better.
I hope this helps! I'm happy to answer any other questions you might have :)
