Action potential and Na+. It is a fact that Na+ ions cross the membrane and enter the cell during the rising phase of the action potential. The process happens because Na ions channels are open. Then the ions channels becomes inactivated/closed for a while. What happens to the Na+ ions that entered the cell?
Product (mathematics) In mathematics, a product is a number or a quantity obtained by multiplying two or more numbers together. For example: 4 Ã 7 = 28 Here, the number 28 is called the product of 4 and 7. The product of 6 and 4 will be 24, because 6 Ã 4 = 24.
What are compatible numbers? Compatible numbers are numbers that look nice or friendly with each other when we do mental calculation to estimate a product, but especially a division. Some examples of compatible numbers when doing division are 400 and 10, 36 and 6, 2400 and 12, and 64 and 8.
