The four most abundant elements needed by the human body are carbon, hydrogen, oxygen, and nitrogen because these are needed in large amounts to support our cells, these are referred to as bulk elements.
Oxygen is the most essential element required by our body. The body requires oxygen in the form of gas which is inhaled by the air around us. All the cells in a human body require oxygen which is transported by the blood inside.
Cell is the most basic and fundamental unit of life. It can be of two types: prokaryotic and eukaryotic. Prokaryotic cell is the primitive one with no true nucleus and eukaryotic cell has a true nucleus and all the cell organelles. Generally eukaryotic cells require abundant amount of oxygen.

The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.

Answer:
The Pepsi he drinks at 10 pm
Explanation:
Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
