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:
all of them apply
Explanation:
In my opinion all of them apply (except the 4th one). Ecosystems can be small, big, have living and non-living parts and they are made of biomes. Not only can ecosystems vary in size, but they can also differ in just about every imaginable biotic or abiotic feature.
Earth’s axis passes through the North and South Poles. It takes Earth 24 hours to rotate once around its axis. Earth revolves once around the Sun in 365 days during a non-leap year.

Answer:
positive feedback
Explanation:
Negative feedback makes the body back to normal, for example, the body releases less glucose into the blood when there is a high blood sugar. Since more growth hormones are released because of the presence of growth hormones, this cannot be negative feedback.
Positive feedback increases a stimulus, for example, the body's release of Oxycontin during labor, causing contractions. These contractions cause more Oxycontin to be released. Since the stimuli is increasing, we can say its positive feedback
