A(t) = ab^t
7 = 12b^20
b = (7/12)^(1/20) = 0.9488
----
Solve for "t" if:
2 = 12^t
[0.9488]^t = 1/6
---
Take the log to solve for "t":
t*ln[0.9488] = ln[1/6]
---
t = -1.7917 /-0.0525
--------------
t = 34.12 minutes (this is when he will have 2mg in his blood)

Answer:
The correct answer is A. The cell membrane is both hydrophilic and hydrophobic due to the presence of phospholipid.
Explanation:
98% of the lipids present in cell membranes are amphipathic, that is, they have a hydrophilic end (which has affinity and interacts with water) and a hydrophobic end (which repels water). The three main types of lipids in eukaryotic membranes are phospholipids, sphingoglucolipids and steroids (especially cholesterol); It is worth mentioning that phosphoglycerides and sphingolipids are found in all cells. The latter, glycolipids and steroids, do not exist or are scarce in the plasma membranes of prokaryotic cells, fungi and some protists. There are also neutral fats, which are non-amphipathic lipids, but only represent 2% of the total membrane lipids.
