The answer is R. The structure of singulair (montelukast), a medication used to manage asthma, the absolute absolute configuration of the chirality center is r and not s. Montelukast is aeukotriene receptor antagonist used to relieve symptoms of seasonal allergies.and used <span>for the maintenance treatment of asthma.</span>
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
Answer:
The answer is D. Calcium
Explanation:
The Electrolyte, according to the reference table in the question, which focuses mainly outside the body's cells is Calcium. Calcium has a value of 8 to 10 mEq / l in the extracellular fluid and 0.01 mg in the intracellular fluid. It is an electrolyte with positive charge: Ca ++.
Answer:
D). genetic drift
Explanation:
Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.
For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.
The plant wilted as the salt absorbed all the water in the large vacuole. For which it shrunk making the plant wilt
