Answer: A. Carbon Dioxide
Explanation: This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2
Convert 24 hours into minutes
24 hours = 1440 minutes
Divide 1440 by 15
There’s 96 divisions
Now take 2^96 power
You will have 7.9 x 10^28 bacteria
The left side of the heart collects oxygen-rich blood from the lungs and pumps it to the body. The left and right sides of the heart are divided by walls<span> called septums. There is an atrial septum that separates the right and left atriums, and a ventricular septum that separates the right and left ventricles.</span>
Answer:
The right answer is (B) the extracted lipids cover twice the surface area of the intact red blood cells.
Explanation:
To explain this statement is necessary to take into consideration the structure of a lipid. On the first place lipids that form membranes are called phospholipids, this means they have one 'head' that is hydrophilic and a tail composed by the lipidic chain that is hydrophobic.
In a biologic context, the phospholipids form the cellular membrane. They do so by a bi-layer disposition, meaning that one the external side of the cell there is a layer of phospholipids with the hydrophilic head and in the internal side, there is a second layer of phospholipids with the hydrophilic head. The hydrophobic 'tails' are in the middle. This disposition is due to the fact that both the external and the internal environments are water based.
Therefore, since each cell has a bilayer membrane of phospholipids, when the cells are dissolved and all the lipids that used to form the membrane are put together, they will occupy twice the surface of the red blood cells.
