Genetic variations lead to different adaptations. What are adaptations? User: Organisms could reproduce exponentially but they don't. Why not? User: What is the current accepted kingdom-domain system?
Weegy: The current system, the Three Domain System, groups organisms primarily based on differences in ribosomal RNA structure. [ Ribosomal RNA is a molecular building block for ribosomes. Under this system, organisms are classified into three domains and six kingdoms. The domains are Archaea, Bacteria, and Eukarya. The kingdoms are Archaebacteria (ancient bacteria), Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia The Archaea and Bacteria domains contain prokaryotic organisms. These are organisms that do not have a membrane bound nucleus. ] (More)

How are DNA and biochemical analysis, embryology, and morphology used to classify organisms?
Weegy: Morphology – Scientists used to classify organisms strictly by morphology (what their bodies looked like), but they have learned along the way that looks aren’t everything. [ First, just because something can fly…doesn’t mean that it is a bird (like a bat). Or, just because something can swim, that does not mean that is a fish (a dolphin for example). So, although scientists use morphology to classify organisms today, it is not their first choice. They use other methods such as Embryology and, more preferably, DNA and Biochemical Analysis. Embryology – Scientists have been using embryology to classify organisms for a while now. Embryology is the study of how an organism develops from an embryo (after the sperm and egg join). It has been found that the more similarly two different organisms develop as embryos, the more closely they are related in their evolutionary lineage. However, again, embryology is not the number one choice for classifying organisms today. DNA and Biochemical Analysis – Today, scientists prefer to use DNA and Biochemical analysis to classify organisms. They feel that it is more accurate in determining the evolutionary lineage of organisms. The closer two organisms are in their evolutionary descent, the closer they should be in our classification system. Our classification system is constantly changing and DNA and Biochemical analysis is being used to reclassify many organisms at this very moment. DNA analysis is when scientists analyze the DNA of an organism and compare it to other organism. If the DNA is very similar, it is believed that the two organisms are more closely related in their evolutionary decent. If the DNA is very different, scientists believe that they are further away in their evolutionary decent. Biochemical Analysis analyzes other biochemicals in the organism, such as enzymes, proteins, chemical reactions, etc. Again, the more similarities the two organisms have, the more closely related they are considered to be. ] ...
