C. It needs oxygen in order to happen
The right answer is 5 - 10 seconds.
The heartbeat check according to ACLS should not take more than that.
The steps for checking your heartbeat are:
Have a watch. It will be used to measure your heart rate.Choose a place to take your pulse. It is better to choose either the neck or the wrist.
Place your fingers so that you feel your heartbeat. Choose a duration for the measurement (5 to 10 seconds).
Start counting.
Multiply the number by 12 if you counted for 5 seconds (by 6 if it is 10 seconds).
The normal frequency is between 50 and 80 bpm
Cells are simply the basic units from which living things are made of, some are single cell organisms while others could be made of thousands, millions or billions of cells.
Metabolism refers to the sum total of chemical reactions that take place usually, but not by any means always, inside cells e.g they could also occur in the blood plasma or in inter-cellular spaces. They are indispensable for sustaining life.
Explanation:
Surprisingly, until recently, not much was known about the genes that control melanin production. 6 were known (MC1R, TYR, OCA2, SLC24A5, MATP and ASIP) and 17 more have been recently identified (DTNBP1, GPR143, HPS3, KITGL, MLPH, MYO5A, MYO7A, SLC45A2, TYRP1, ERCC6, GNAS, HERC2, IRF4, OBSCN, SKC24A5, TPNC2 and MITF), all of them directly or indirectly related to the process of melanin formation and distribution. Since there are so many different genes, if we count all the possible alterations, many different color variants can be produced.
