There are so many capillaries in the lungs because capillaries are the only cells small enough to continuously carry the blood because the lungs and small intestine need more blood.
The transfer of the energy in the living organisms from one cell to another occurs via the ATP (Adenosine Triphosphate) molecules. The functional group involved in this transfer of the energy is the phosphate group.
The ADP (Adenosine diphosphate), and ATP (Adenosine Triphosphate) are the molecules involved in the transfer of the energy from one cell to another.
Hence, the answer is 'phosphate'.
Darwin also suggested a mechanism for evolution: natural selection, in which heritable traits that help organisms survive and reproduce become more common in a population over time. A heritable trait is one that's passed on from parents to children by way of genes.
Answer: premaxilla bone (or maxilla) and the maxillary beak (or rhinotheca).
Explanation:
The beak is composed of keratin, the same tough, insoluble protein found in fingernails, hoofs, antlers and horns. A bird's bill comprises two parts. The upper portion of a bird's bill is called the maxillary rostrum, which consists of the premaxilla bone (or maxilla) and the maxillary beak (or rhinotheca).
The phenotype is called Roan, a mix of white and red
