Answer:
Na+ only
Explanation:
Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.
This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.
In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.
Thus, Na+ only is correct.
The word "cycle" in cell cycle refers to the regular pattern of growth, DNA duplication, and cell division that occurs in eukaryotic cells.
The cell cycle is the term that describes the development and growth of a cell, after its formation and until its reproduction (division into two daughter cells). In eukaryotic cells (cells that include a nucleus) the cell cycle is comprised of two major phases, the interphase and the mitosis. During interphase, the cell grows larger and duplicates its genetic material. During mitosis, the cell divides its genetic material and cytoplasm, creating two daughter cells.
Answer:
According to neuroscientists, everything we perceive is a construction of the brain, thus, human perception is largely a linguistic and cultural process that assigns meaning to the millions of sensations we encounter daily.
Explanation:
The answer is most likely to be D, because when the photon hits an electron within a molecule of chlorophyl, the energy from the light excites an electron from its normal energy level to an excited energy level!
Because the earths orbit around the Sun is not in the same plane as the moon orbit around the earth.
