Answer:
51.859 grams
Explanation:
Given:
Mass of sugar in the crunch cereal per serving= 11.0 grams
Mass of cereal served per serving = 60.0 grams
Molar mass of the sugar (C₁₂H₂₂O₁₁) = ( 12 × 12 + 22 × 1 + 16 × 11 ) = 342 grams
Number of moles of sugar per serving = Mass / Molar mass
= 11.0 / 342
= 0.03216 moles
Now,
0.03216 moles sugar requires 60 grams cereal
for 0.0278 moles of sugar, cereal required = (60 / 0.03216) × 0.0278
or
for 0.0278 moles of sugar, cereal required = 51.859 grams
Answer:
a. Remaining at rest requires the use of ATP.
Explanation:
The resting membrane potential is maintained by the sodium-potassium pump. The sodium potassium pump does this by actively pumping sodium ions out of the cell and potassium ions inside the cell in a ratio of 3:2. This movement of ions by the sodium-potassium pump is against their concentration gradient. In a neuron at rest, there are more sodium ions outside the cell than there are inside the cell. Also, there are are more potassium ions inside the cell than there are outside the cell. However, there are ion channels through which these ions enter and leave the cell. Sodium ion channels allow sodium to enter the cell following its concentration gradient, whereas, potassium ion channels allow potassium to leave the cell following its concentration gradient. However, more potassium ions leave the cell than do sodium ions enter the cell because of the higher permeability of the cell to potassium ions.
In order to maintain the resting membrane potential, the sodium potassium pump powered by the hydrolysis of an ATP molecules pumps sodium ions out of the cell and potassium ions into the cell.
<em>Therefore, the correct option is A, as ATP is needed by the sodium-potassium pump in order to maintain the resting membrane potential.</em>
Answer:
I think Water because it keeps you dehydrated. You will still survive with out any food or any place to live but it's not air i know that for a fact because we need oxygen to live.
