Answer: Hemoglobin
Explanation: Hemoglobin is a protein very rich in iron found in red blood cells and is responsible for the transportation of Oxygen from the lungs to the whole body. Oxygen binds to the hemoglobin in red blood cells and the red pigmentation of blood that is highly oxygenated is due to the hemoglobin content found in RBC's.
<span>The answer is B) cell wall. The cell wall is a structure important cell protection and shape. It is necessary for the survival of unicellular organisms, such as Archaea and bacteria. Plants, some fungi, and algae also have cell walls with major function in structural support and protection against environmental conditions and infection. However, animal cells do not have cell walls.</span>

Answer:
All because they not representative of every possible scenario.
Explanation:
They use current knowledge and scientific date‚but as those are subject to change‚the based off that knowledge and data subject to change as well.
A polygenic trait can have many possible genotypes, producing many possible phenotypes
Explanation:
The polygenic trait is influenced by more than one gene leading to the possibility of many genotypes and phenotypes. This trait itself is a characteristic or a phenotype which is controlled or influenced by multiple genes.
The phenotypes are produced with addition of each dominant allele. Phenotypes like height, skin color of a person are controlled by many genes and the dominant alleles finally produce the respective phenotype.
These does not follow Mendel’s rule of inheritance, where one phenotype is controlled by one genotype.
