<span>The four biological macromolecules are carbohydrates, lipids, proteins and nucleic acid. These macromolecules are known as polymers and are built when monomers join together by a process known as the dehydration reaction. The dehydration reaction is a chemical reaction that produces water (H2O) and the result is the covalent bonding of the two monomer molecules. The monomer molecules consist of nutrients found in the soil, as in the case of plants, and the intake of food as in the case of animals.

Regulation- the process of the blood sugar becoming regulated by insulin (glucose).
Independent grouping of qualities happens amid meiosis in eukaryotes. Meiosis could be a sort of cell division that diminishes the number of chromosomes in a parent cell by half to deliver four regenerative cells called gametes. In people, diploid cells contain 46 chromosomes, with 23 chromosomes acquired from the mother and a moment comparative set of 23 chromosomes acquired from the father. Sets of comparable chromosomes are called homologous chromosomes. Amid meiosis, the sets of homologous chromosome are separated in half to make haploid cells, and this partition, or grouping, of homologous chromosomes is arbitrary. This implies that all of the maternal chromosomes will not be isolated into one cell, whereas the all fatherly chromosomes are isolated into another. Instep, after meiosis happens, each haploid cell contains a blend of qualities from the organism's mother and father.
Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
