An increase in blood carbon dioxide content causes hemoglobin to ________. release all bound carbon dioxide molecules bind more oxygen molecules bind more H release more oxygen molecules denature
An increase in blood carbon dioxide content causes hemoglobin to release more oxygen molecules. Details about hemoglobin can be found below.
What is hemoglobin?Hemoglobin is the iron-containing substance in red blood cells that transports oxygen from the lungs to the rest of the body.
Hemoglobin consists of a protein (globulin) and heme (a porphyrin ring with an atom of iron at its centre). This justifies its oxygen affinity.
However, excess carbon dioxide in the blood causes blood pH to decrease, resulting in hemoglobin proteins releasing more oxygen molecules.

Approximately 2Give an example of a polymer formed by addition polymerization.
Answer:
During the addition polymerization, all monomers are consumed and no byproducts are formed. Common examples of addition polymerization are polyethylene, polyvinyl chloride (PVC), acrylics, polystyrene, polytetrafluoroethylene, and polyoxymethylene (acetal).
What is meant by addition polymer?
In polymer chemistry, an addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water.

Divers get "the bends" if they come up too fast because the gas in their blood expands, forming bubbles in their blood. If a diver has 5.0 mL of gas in his blood under a pressure of 250. atm then rises instantaneously to a depth where his blood has a pressure of 50.0 atm, what will the volume of gas in his blood be?
Solve without converting volume into dm³ as it will led into same answer
According to Boyles law
P1V1=P2V25(250)=50V21250=50V_2V_2=25mLAccording to Boyle's law, the volume of gas in his blood will be 25 ml at constant temperature.
What is Boyle's law?
Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.
According to the equation the unknown pressure and volume of any one gas can be determined if two gases are to be considered.That is,
P₁V₁=P₂V₂
substitution gives V₂=250×5/50=25 ml.
Therefore, the volume of gas in his blood will be 25 ml at constant temperature.
