Explanation:
Hemoglobin is a blood hemoprotein, with a molecular mass of 64,000 g / mol (64 kDa), of a characteristic red color, which transports the dioxygen (commonly called oxygen), O2, from the respiratory organs to the tissues, the dioxide of carbon, CO2, from the tissues to the lungs that eliminate it and also participates in the regulation of blood pH, in vertebrates and some invertebrates.
Hemoglobin is a quaternary structure protein, which consists of four subunits. This protein is part of the hemoprotein family, since it has 1 heme group in each subunit
Hemoglobin is a tetrameric protein, which consists of four polypeptide chains with different primary structures. ... Each hemoglobin polypeptide chain is attached to a heme group to form a subunit. The four subunits of hemoglobin in its quaternary structure form a tetrahedron.

Answer:
it would actually be B.
Explanation:
you may ask why, well its because the fur color is debated weather the fur color will be recessive or dominate, its not up the nature and environment. Lets say the mouse got a recessive fur color from its mom(white fur) and a dominate fur color from its dad (brown), the offspring will obviously get the dominate trait and get brown fur. So that is why it would be B. I am a A student in science, so i know what i'm talking about when it comes to science.
The blood is collected in heparinized capillary tubes to prevent clotting. Heparin is a blood thinner and this anticoagulant is produced naturally by mast cells and basophils. But heparin can not dissolve or break the preformed clots.
