Answer:
Peripheral membrane proteins (select one):
D) are generally noncovalently bound to membrane lipids.
Explanation:
Peripheral membrane proteins are membrane protenis that adhere only temporarily. These don't penetrate deeply into the lipid bilayer, just penetrate the peripheral regions. Also <em>they are bound to either face of the membrane by noncovalent interactions.</em> There are many different categories of peripheral membrane proteins: Membrane-targeting domains; transporters of small hydrophobic molecules
; electron carriers
; Polypeptide hormones, toxins, and antimicrobial peptides; structural domains; enzymes.

Answer:
Nitrogen-fixing bacteria will significantly outnumber those incapable of fixing nitrogen
Explanation:
Nitrogen-fixing bacteria are capable of growing in a medium lacking organic Nitrogen. They convert (fix) atmospheric Nitrogen (Nitrogen is abundant in air) into organic substrates. Hence, they will grow in the enrichment medium described. This is the kind of medium used to isolate nitrogen-fixing bacteria.
Non-nitrogen fixing bacteria require an organic form of Nitrogen for growth. Hence, in a medium with no nitrogen, they will rely on the Nitrogen fixers. This means delayed growth for them.
A culture medium also has limited nutrients, so the slow growers will have little or no nutrients left.
Therefore, the Nitrogen fixers will have competitive advantage and significantly outnumber those incapable fixing nitrogen.
