The first land plants appeared around 470 million years ago, during the Ordovician period, when life was diversifying rapidly. They were non-vascular plants, like mosses and liverworts, that didn't have deep roots
The statements that are true for S-waves are:
A. They can only travel through the solid rock inside Earth.
C. They are the second type of waves detected after an earthquake.
The S-wave is the second wave that gets detected by the seismograph. These waves do not travel through the liquid medium. They are also slower than the initially detected P-waves. S-wave also are more destructive than the P-waves but are relatively less destructive than the L-waves and the Rayleigh waves.
The bulb contains a chemical called lycorine which can cause various symptoms if eaten (so in a way poisonous)
The red spider lily is associated with death. there is a popular japanese name (Higanbana) for it which means flower of the after life.

aside from the big ones which are the DNA and RNA:
Some
proteins (such as telomerase) have bits of attached RNA. Ribosomes have a bit
of RNA. <span>
<span>We also have adenosine triphosphate, which is the energy koin
of the cell. </span></span>
The probable reason for the case would be that the sea floor 200 million years ago is now above the sea level.
The ocean floor is the eventual recycling center. While the Earth's continental crust can prevail for billions of years, the movement of tectonic plates results in subduction, that is when the crust of the ocean is pushed down into the present mantle. So, the ocean floor hardly endures longer than 200 million years.
