Answer:
Lipids and proteins
Explanation:
It gets lipids from the membrane of the host cell it attaches to.
The proteins on the envelope are from the original virus itself.
Competitive inhibition vs allosteric inhibition
In competitive the substrate and inhibitor bind at the same active site - pretty straightforward. In allosteric regulation (speaking specifically about inhibition here), the inhibitor is binding at a site other than the active site, and changing the enzyme in some way to make it inactive.
Mutualism because both animals benefit. The Elephant gets relived from the parasites that are on it and the bird gets food.

Explanation:
Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.
