Answer:

Sodium-Potassium Pumps

Explanation:

Sodium-Potassium Pumps written as Na-K Pumps are ion channels found in the cell membrane of nerve cells. These pumps are responsible for maintaining the different ion concentrations across the membrane and help in polarization and depolarization of the membrane by influencing membrane potential. During ion exchange these pumps transfer three sodium ions from inside to outside of the cell and two potassium ions from outside to inside of the cell. In this way they maintain the ion concentration gradient across membrane.

You are required to prepare 500 ml of a 6.00 M solution of HNO3 from a stock solution of 12.0 M. Describe in detail how you woul
andriy [413]

Answer: 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.

Explanation:

According to the dilution law,

C_1V_1=C_2V_2

where,

C_1 = concentration of stock solution = 12.0 M

V_1 = volume of stock solution = ?

C_2 = concentration of diluted solution= 6.00 M

V_2 = volume of diluted acid solution = 500 ml

Putting in the values we get:

12.0\times V_1=6.00\times 500

V_1=250ml

Thus 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.

The land breeze arrow is correct

The rest are incorrect.

Warm air should 'rise' by the land

This air then moves towards the sea and cools down

The cool air would then sink
