Answer:
There is not junk DNA
Explanation:
All DNA is necessary for the cycle in our bodies
Depolarisation
A membrane depolarization is a decrease in the potential difference between the outside of a cell and the intracellular medium, on either side of the plasma membrane, most often due to a positive ion input (Na +, Ca ++, etc.) inside the cell or sometimes due to the release of chloride ions, and involved in the mechanisms of transmission of nerve impulses and muscle contraction.
Hyperpolarization:
The depolarization is followed by a repolarization, thanks to the output of an equivalent quantity of ions k + which causes the return to the state of equilibrium. Then there is a hyperpolarization due to the output of more k + ions than Na + ions, because the potassium channels are slow to close. Finally there is a return to the resting potential.
Hyperpolarization is a term opposite to that of depolarization, it refers to values lower than that observed during the resting potential.
The correct answer is D. Vacuole
Explanation:
In cells, the vacuole is the organelle in which different substances or solutions are stored, this includes wastes, water, food, and even solids that the cell does not require because they are waste and therefore might contaminate the cell or substances the cell store to be used later. Due to this, the vacuole is a chamber that contains specialized membranes that allow certain substances to go in or out. Also, vacuoles can be found in plants, animals, fungi, among others although in organisms such as plants they are bigger. According to this, it is vacuoles the organelle that stores wastes, water or food.
