Why is some blood bright red?
because of the presence of oxygen gas in the haemoglobin of the red blood cell.
Red blood cells with high oxygen concentrations are bright red because of the presence of?
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.
What color is BTB when oxygen is present?
In the presence of oxygen, blood is typically bright red due to the oxygenated hemoglobin molecule.
What kind of simple chemical reaction goes on in a firework?
the white bright light produced in fire works is due to burning of magnesium in the presence of oxygen magnesium+oxygen=magnesiumoxide
Is bloood brighter with oxygen or no oxygen?
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.
How does the level of oxygen change as altitude increases?
As altitude increases, the level of oxygen decreases. This is because the air becomes thinner at higher altitudes, leading to lower oxygen concentrations.
What is microaerophile?
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
What color will blood exhibit when it has high oxygen?
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.
Is blood red because it has rich oxygen in it?
Yes, oxygenated blood is bright red
How does oxygen enter the capillaries?
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
How does the percentage of oxygen in the air change as altitude increases?
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.
Are hydrogen and helium and oxygen poisonous?
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.
