It depends upon the amount of natural selection that occurs. None of these. Genera to Family to Order to Species to Phylum to Kingdom to Class e. Class to Family to Genera to Kingdom to Order to Phylum to Species 16. A number of genetic maladies, like maple syrup urine disease and Ellis-van Crevald syndrome, are found in the population of the Amish of Lancaster, Pennsylvania at rates higher than the surrounding general population and the population from which the Amish were originally derived. Several populations of small lizards live in the Tennessee River system, but individuals can move from population to population.
Genetic analysis indicates that all the populations are very similar.
The first cells on the planet almost certainly lived off of the nutrients that had built up in the oceans since they were incapable of producing their own food. DNA contains deoxiribose sugar and RNA contains ribose sugar. DNA is more stable as a double helix and RNA usually occurs as a single strand. DNA bases include A, T, C and G and RNA bases include A, U, C, and G. e. DNA is relatively immobile, confined to the nucleus, and RNA is mobile and moves from the nucleus to the cytoplasm. Eventually, cells arose that could harness light energy and use it to produce chemicals that store energy.
