this better to say blood with high CO2 concentration is dark and blood with high CO (Carbon monoxide toxemia) is bright, so O2 saturated blood is just NORMAL.
because of the presence of oxygen gas in the haemoglobin of the red blood cell.
Red blood cells are red due to the presence of the protein hemoglobin. Each molecule of hemoglobin has 4 molecules of iron associated with it. When oxygen bonds to the iron it causes a reaction that makes the hemoglobin appear red. And because the density of hemoglobin in is so dense in a red blood cell (approximately 97% of its volume is filled with it) the cell also looks red.
In the presence of oxygen, blood is typically bright red due to the oxygenated hemoglobin molecule.
the white bright light produced in fire works is due to burning of magnesium in the presence of oxygen magnesium+oxygen=magnesiumoxide
Blood is brighter red when it is oxygenated, as oxygen binds to hemoglobin in red blood cells to form oxyhemoglobin, giving blood its bright red color. Deoxygenated blood appears darker red due to the presence of reduced hemoglobin.
As altitude increases, the level of oxygen decreases. This is because the air becomes thinner at higher altitudes, leading to lower oxygen concentrations.
Microaerophiles are microorganisms which are unable to grow when oxygen concentrations reach those found in air (20%) but nevertheless whose growth requires the presence of some oxygen (e.g., 2 to 10%). "Microaerophiles appear to grow best in the presence of a small amount of free oxygen. They grow below the surface of the medium in a culture tube at the level where oxygen availability matches their needs
Blood will appear bright red when it has high oxygen content. This is because oxygen binds to hemoglobin in red blood cells, forming oxyhemoglobin, which gives the blood its bright red color.
Yes, oxygenated blood is bright red
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
As altitude increases, the percentage of oxygen in the air decreases. This is because the air becomes thinner at higher altitudes, leading to lower oxygen concentrations.
Oxygen can be toxic in hydro concentrations, but it is essential in lower concentrations. Neither helium nor hydrogen are toxic, but they can displace oxygen simply because they take up space and so can cause asphyxiation. Hydrogen is dangerous because it is highly flammable.
