Answer:
The dissolving power of water is very important for the transport of nutrients in blood.
Explanation:
Water is known as the "universal solvent" because it can dissolve more substances than any other liquid. The dissolving power of water means that it can effectively transport nutrients, chemicals, and minerals. Plants rely on water to carry dissolved nutrients from the soil. Animals also benefit from water as a solvent.
The answer is duplications.
Gene family consists of several similar genes. Duplications of single genes, exons, multigene families, or whole genome have given rise to families of related genes. The example is the globin family of genes in primates. About 500 million years ago, a duplication of single globin gene began. Much later, during primate evolution, the additional duplications occurred together with some point mutations. So the end result is diversity in globin chains that arose from original globin gene.
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein.
