Answer:
The invention of active drug loading method improves the encapsulation efficiency of some ionizable hydrophilic drugs (weak acid or weak base). The specific method is to construct pH gradient inside and outside the liposome, and then use the solubility difference of ionizable drugs under different pH conditions to realize the drug loading. With this method, the drug encapsulation rate can reach more than 95% and the drug loading can reach about 10%.

Answer:
1.0 mole per dm3 sodium chloride solution
Explanation:
<em>The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established. </em>
Hence,<u> the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick</u> when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.
Answer:
Farts — also called flatus (say: FLAY-tuss) or intestinal (say: in-TESS-tuh-null) gas — are made of, well, gas! When you eat, you don't swallow just your food. All of these gases in the digestive system have to escape somehow, so they come out as farts! Gases are also what can make farts smell bad.
Answer:
D
Explanation:
Population is generalized to all individuals.
Answer:Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
