Answer:
because when it gets cold, it weakens our immune system and we become more vulnerable to sickness
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.
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
