Answer:
7.5 mg/L
Explanation:
As the drug elimination is following the first order of reaction mechanism so for such reactions the following equation relates the final and initial amount
The values given in the question are
Initial concentration = 120 mg/L
Half life = 3 hours.
Time = 12 hours
Thus, putting the given values in the above equation, we get
Thus, after 12 hours the concentration of the remaining drug will be 7.5 mg/L.
The correct answer to this question is this one: "C. The plant exists as a diploid organism, and at other times as a haploid." Vascular plants exhibit alternation of generation. The alternation of generation is presented as the plant exists as a diploid organism, and at other times as a haploid.<span>

Answer:
Cohesion; the water molecules attract each other and are responsible for the surface tension of water.
Adhesion; the water molecule is also able to attract other non-water molecules. This allows water to be able to ‘cling’ to the sides of a capillary tube.
The complementary action of these two forces allows water to rise in a narrow capillary tube such as the xylem tissues of plants.
Answer:
B
Explanation:
The experimental drug has a direct effect on the dependent variable which is the presence of the headache.
I believe the answer is 90%.
