Answer:
According to the result recorded, there was no cholesterol in the albumin solution. This is probably because the cholesterol is in the egg yolk and not the egg white. In order to get a positive response on the presence of cholesterol in eggs, an egg yolk albumin stock needs to be prepared. So using the same procedure as before and only replacing the egg yolk for the egg white, prepare a 0.5 mL of egg yolk with 4.5 mL distilled water mixture in a test tube. Follow the steps given in the lab manual to check for presence of lipids in this albumin stock. Take a filter paper and add one drop of Sudan III solution onto it, let it dry and then place a drop of the stock prepared and analyze if the color transfer happens.
Hope that answers the question, have a great day!
Answer:
You would pop. And that would be sad.
Explanation:
The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.
