Biodiversity hotspots

This is an overview of the world's most diverse areas. It includes any area with over 0.5% of either the world's vertebrate species or plant species. Some of these locations are under serious threat due to habitat degradation and introduced species, so if you want to see these places in their curren...

Mosses are considered to be non-vascular plants because they lack xylem and phloem. The phloem and xylem are used to transport fluids and gases through vascular plants. Instead, in mosses, water is transported by cell-to-cell diffusion and this inefficient way to transport fluid limits the height an...

The volume of air that is inhaled varies between person and with the depth of each breath. Obviously some breaths inhale more air than others and inhalation can range between ~400ml to ~5L. The efficiency of respiration also reduces with age and is reduced in smokers. Anyway, to give you an answer: ...

My first thought would be that r-selection strategy would be the most the most successful, mostly because it sounds like there is a high amount of variability in the environment.

That's true, it isn't really answering the question of what is the origin of life and is really only considering what might be the origin of life on Earth. I wasn't trying to say there is a consensus on the origin of life, but rather just saying that that is what was said in that documentary series ...

I'm sorry but plants still respire during the night. Their cells are still doing things other than photosynthesizing that require energy.

Topic: Is thiamin (thiamine) amine or not?

From what it looks like to me, thiamine might not be an amine because the amino group is connected to an aromatic ring. I know phenylamines are amine groups connected to benzene rings. In thiamine, the amine group is connected to a pyrimidine ring. So I'm not sure but this may be why thiamine is not...
