Answer:
A. Compounds contain fixed ratios of different elements.
Explanation:
Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition.
<span>The bacteria are probably eubacteria because they live on common plant leaves.
</span>Archaebacteria living in extreme places(like the thermophile bacteria that in a volcano) while eubacteria lives in normal places. L<span>eaves of common houseplants is not an extreme location, so </span>Archaebacteria is less likely found there<span>. </span>Both <span>eubacteria and archaebacteria could be autotroph or heterotroph, so the information cannot be used to conclude anything.

Charlidamelio is overrated
C seems like the correct answer
<span>adding a unit to move a susceptible group enough to prevent metabolism is known as shifting.
These phenomena happen especially for liposoluble organism circulating in blood like drugs an hormones.
these molecules circulating blood can be divided into two forms :
The free-form: which is the active part, it circulates freely in the blood, but are easily metabolised.
The bound form: it can be bound to other molecules from the organisms depending on its affinity like proteins (albumin, glycoproteins). this form is not active but is prevented from metabolism.
Competition for bounding proteins can happen between two drugs for example. If they have a different degree of affinity for proteins, then the most affine will displace the less affine from the protein and bound it, and that is call shifting</span>
