While there is no graph provided and I cannot find the graph online, I will base my answer through theory.
In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
Answer:
c. Only 1, 2, and 3 are correct.
Explanation:
Metabolism includes all the chemical reactions that occur inside a living cell. Metabolism consists of multistep chemical pathways. The metabolic pathways are of two types: catabolic pathways and anabolic pathways. The catabolic pathways are the chemical pathways that breakdown the complex substances in the simpler ones and result in the release of energy. Catabolism is exergonic in nature.
On the other hand, anabolic chemical pathways form complex substances from the simpler elements and require an input of energy. The formation of long chains of the polypeptide by joining monomer amino acids together is an example of anabolism. The breakdown of the polypeptide chain into the amino acids is an example of catabolism.
