Which structures join with the cell’s membrane during exocytosis?

erma4kov [3.2K]

Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.

A certain flexible weather balloon contains 7.4 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur

<h2>The new volume of the balloon at the top of Pikes Peak is 10.2 L</h2>

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 577.0 torr

$P_2$ = final pressure of gas = 400 torr

$V_1$ = initial volume of gas = 7.4 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $20.6^oC=273+20.6=293.6K$

$T_2$ = final temperature of gas = $7.5^oC=273+7.5=280.5K$

Now put all the given values in the above equation, we get:

$\frac{577.0\times 7.4}{293.6K}=\frac{400.0\times V_2}{280.5K}$

$V_2=10.2L$

Thus the new volume of the balloon at the top of Pikes Peak is 10.2 L

Explain why indicators are useful for measuring pH

ycow [4]

Explanation:

pH indicators are weak acids that exist as natural dyes and indicate the concentration of H+ (H3O+) ions in a solution via color change. A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing.

A chemist is using a solution of HNO3 that has a pH of 3. 75. What is [H ] for the solution? Round to the nearest hundredth. × 1

Alexeev081 [22]

The estimation of the acidic and the basic character of a solution is called and defined by the pH. The $\rm [H^{+}]$ concentration of the solution will be $\rm 1.77\times 10^{-4}.$
