Answer:
As part of the phosphate group, it is a component of DNA, RNA, ATP (adenosine triphosphate), and the phospholipids that form all cell membranes.
California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.
Some common elements that are gaseous state at room temperature are:
Oxygen
Nitorgen
Fluorine
Chlorine
Hydrogen
Helium
In addition, all of the elements in group VIII are gases too, they have an octet of electrons (complete outer electron shell) , they're really stable and therefore they're called noble gases. Some examples from group VIII include helium, krypton, xenon etc.
Substance exist as gases in room temperature is due to their boiling point, where is it lower than the room temperature (usually around 25°C). If their boiling point is higher than room temperature, they should exist as either solid or liquid, which is how the majority of the elements in the periodic table is.
