The rapid depolarization phase of the action potentials of myocardial contractile cells is due to Na⁺ ion.
The depolarization is caused when Na⁺ ions rapidly enters into neuron through open sodium channels. Sodium ions plays important role in various physiological process such as regulating blood volume, ph regulation, maintaining blood pressure, energy metabolism,osmotic equilibrium, excitation-contraction coupling, maintenance of cellular homeostasis, development and growth.

Answer;
The above statement is false.
The ballistic method of developing flexibility is not the safest form of stretching.
Explanation;
-Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. It involves stretching by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position. An example is the ballistic method of touching your toes would be to bounce and move toward your feet.

4) Class is dicotyledonae.
5) Order is sapindales.
6) Family is anacardiaceae.
7) Genus is magnifera.
8) Specie is indica.
Explanation:
Eukaryote are those organisms having true nucleus. Dicotyledons are those plants in which seeds have two cotyledons. Mango plant belongs to Angiosperm i. e. seeds are hidden in the ovary.
