<h2>Expiration is typically a passive process that happens from the relaxation of the diaphragm muscle (that contracted during inspiration). The primary reason that expiration is passive is due to the elastic recoil of the lungs. Exhalation begins when inhalation ends.

Yes, this is correct!
Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)
Isotopes are atoms with the same atomic number but different atomic weights. Atoms of different isotopes are atoms of the same chemical element. They differ in the number of neutrons in the nucleus.
Archaebacteria are like Eubacteria, which are just able to survive dangerous conditions, such as high salinity, extreme temperatures, and no oxygen.
Eubacteria are your garden-variety prokaryotic organisms that can cause the common cold and make bread rise, which don't have nuclei.
Fungi are similar to plants in the way that their cells are structured, except they have cell walls made of <em>chitin</em>, instead of cellulose like Plants. They decompose food and eat it using chemosynthesis, breaking it down into organic matter, which allows for the cycling of materials through a food chain.
Protista is really tough. You see, protists are basically a fancy word scientists picked instead of "miscellaneous", because there are plant-like, fungi-like, and animal-like protists. They really have no defining characteristics to speak of except that they have weird quirky qualities that don't allow them to fit in any groups.
Hope this helped! :)
