When did seedless vascular plants evolve?
The first seedless vascular plants evolved over 439 million years ago during the Silurian period. These early vascular plants developed the ability to synthesize lignin which gave them support.
How does part of a tree become fossilized?
If a piece of the tree does not rot (decompose) when it dies, and it rests (initially) in a very wet environment, then, over a long period of time, organic atoms (compounds) will be replaced by inorganic atoms (compounds). Thus a fossil.
What importance do vascular plants have to humans?
1. Vascular plants are very tall so the non-vascular plants are food for them. 2. The spore-producing plants provide food for humans.3. And vascular plants provide shade for other plants during hot, dry seasons.

What is Ehliers-Danlos Syndrome Dermatosparaxis Type?
To get horny for a long period of time. Um, no. And if that lasts more than four hours, dude, call your doctor. ;-) The Dermatosparaxis Type of EDS (formerly Type 7C) is extremely rare, with about 10 cases identified ever. It is characterized by extremely fragile, sagging skin and is caused by a defect in the ADAMTS2 gene. Mutations in this gene cause a dramatic reduction in the enzyme produced by this gene; the reduction in the enzyme means that procollagen is not processed correctly, so that collagen fibrils aren't formed correctly, so that the connective tissue within the body is very weak. My understanding is that the common symptoms of the three more prevalent types (hypermobility, classic, and vascular) can be present in any of the more rare forms of EDS.
What plants first developed during the Sirulian period?
Vascular
The Devonian period corresponds to the diversification of seedless vascular plants?
true
What period of the paleozoic Era did the first vascular plants invade the land successfully and became widespread?
Silurian period
During which period did eurypterids swim the oceans and the first jawed fish and vascular plants evolve?
Silurian period
Could a fossil found in a river be a fossilized snake?
Yes, it could because that river might not have been there back in the time period of the snake. The snake would have died, became fossilized, then the river formed over. The snake was BEFORE the river.
When did vascular plants most likely evolve What is the evidence for the time scale?
During the Devonian Period is when vascular plants most likely evolved. The evidence of this time scale is that fossils dating back to the Devonian Period have been found.

Does the megalodon still alive?
The megalodon is only known from fossilized teeth. They date from 25 to 2 million years ago. Megalodon died out during the early Quaternary period of the Cenozoic era.
Who identified the nucleus?
In the early period of the 1900s, Ernest Rutherford became famous for his discovery of the nucleus. He was an English physicist.
