Answer:
<em>6</em><em> </em><em>minutes</em>
EXPLANATION:
The brain can survive for up to about six minutes after the heart stops. The reason to learn cardiopulmonary resuscitation (CPR) is that if CPR is started within six minutes of cardiac arrest, the brain may survive the lack of oxygen. After about six minutes without CPR, however, the brain begins to die.

I think the answer is photosynthesis 2
Answer:
there are two types of endoplasmic reticulum, rough endoplasmic reticulum and smooth endoplasmic reticulum, the rough endoplasmic reticulum is the site of protein manufacture( because it has ribosomes) whereas the smooth endoplasmic reticulum manufactures fat molecules or lipids. these lipids helps in membrane biogenesis, which is the process of formation of plasma membrane. the main function of the endoplasmic reticulum is that it serves as channel for transportation of proteins etc between various cells or a cell organelle and another cell. In the liver, detoxification of poisons take place due to the help of smooth endoplasmic reticulum.
