All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.
<span>Chest
compression can save the lives of patient in cardiac arrest as it generate a
small but critical amount of blood flow to the heart and brain. It provides
oxygen quickly to the brain, heart, lungs and other organs until normal
function of the heart and lung restored. When the patient is unresponsive without
definite pulse or normal breathing then the responder should assume that the
patient is in cardiac arrest. CPR or chest compression is used to keep oxygen
circulating around the body until a defibrillator can be used or until the
ambulance arrives. Moreover, defibrillator is a device used to help blood flow
in order to help the patient survive or recover from cardiac arrest. This
procedure can momentarily stops the heart and the chaotic rhythm and often
allows the normal heart rhythm to resume. However, chest compression be given
when the patient has no pulse while CPR is performed when the patient is
unresponsive, not breathing and has no pulse.</span>
The correct answer is A. The oxygen molecule accepts electrons from a compound called cytochrome a3. Cytochromes contain a central Iron atom that can either be in the oxidised state(ferric state) Fe3+ or reduced state(ferris state) Fe2+. The cytochrome is oxidized by giving the electron to O2(O2 is reduced).O2 becomes 2O- that quickly react with H+ to form H2O.
