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 option that says: Sister chromatids separate from each other and migrate to opposite ends of the cell.
Explanation:
This question wants to test us on a very interesting part in genetics that is Cell Cycle, Mitosis and Meiosis.
In mitosis, the cell divide to produce or generate two daughter cells that has the identical genetic infomation just as the one in the parent cell. After mitosis, we have Cytokinesis.
For meiosis, it is divided into two that is meiosis I and meiosis II. Meiosis I is about the separation of homologous chromosomes pairs while meiosis II is about the separation of chromosome into two chromatids.
In anaphase II of meiosis, "Sister chromatids separate from each other and migrate to opposite ends of the cell" after the division of the centromere.
Answer:
Explanation:
Plants, algae, and certain bacteria can photosynthesize and make their own food by converting carbon dioxide, water, and sunlight to glucose and oxygen.
Animals cannot undergo this process and produce their own food, so they have to eat food to obtain glucose.
Animals get glucose and energy by <u>consuming plants or other animals.</u>

Answer: The correct answer is Vacuole
Explanation:
The vacuole is an organelle found in the central portion of plant cells, and is usually filled with cell sap that acts as a "store house" for many substances entering into the cell.
Therefore, the herbicide waste absorbed by the plants will be stored in the VACUOLE.
