Answer:

C. ATP is required to move substance A into the cell.

Explanation:

As the model shows a cell with the movement of substances A and B, so the correct statement following the model is "ATP is required to move substance A into the cell".

This is so because ATP is required by a cell to move the substance such as ions across a membrane against a concentration and at the same time another substance moves out of the cell by the process called diffusion.

<u>As in the model, we can see substance A is moving in the cell while B is moving out of the cell (distance between cell membrane and substance B is more).</u>

Hence, the correct answer is "C. ATP is required to move substance A into the cell."

High doses of caffeine interfere with the dna replication checkpoint mechanism in mammalian cells. why then do you suppose the s

Kipish [7]

Molarity = $\frac{Solute(in Moles)}{Solution (in Liters)}$

Moles of Caffeine = Mass of Caffeine/Molar Mass
Mass = 100 mg = 0.1 g
Molar Mass = 196 g/mole

Moles of Caffeine in one cup = 0.1/196 moles
= 5.102 * 10^-4 moles

If one cup of coffee is ingested (A typical adult contains about 40 liters of water),

Molarity of caffeine = [(5.1 * 10^-4)/ 40] M
= 0.012755 mM

The toxic molarity of caffeine in the body 10mM

How many cups will be toxic?
= Toxic Molarity/ Molarity of 1 cup
= 10/ 0.012755
= 784

In other words, you would have to drink 784 cups of coffee to reach the dose required to interfere with the DNA replication checkpoint mechanism.
