Are the halogens group 7 or group 17?

If by seven you mean 7A than the answer is both. 17 is the newer system which the scientific community was hoping to establish, which would get rid of the A and B classification. 7A is the older system in which all representative elements are given an A and transition metals are B.

What kingdoms do bacteria belong to?

There are two types of bacteria...Archaebacteria and Eubacteria. Archaebacteria are ancient bacteria that are in extreme environments (hot springs, etc.). Eubacteria are the newer bacteria, those that cause illness or in food production, etc.


What is the main problem with classifying protists?

Historical classificationsThe first division of the protists from other organisms came in the 1830s, when the German biologist Georg August Goldfuss introduced the word protozoa to refer to organisms such as ciliates and corals.[4] This group was expanded in 1845 to include all "unicellular animals", such as Foraminifera and amoebae. The formal taxonomic category Protoctista was first proposed in the early 1860s by John Hogg, who argued that the protists should include what he saw as primitive unicellular forms of both plants and animals. He defined the Protoctista as a "fourth kingdom of nature", in addition to the then-traditional kingdoms of plants, animals and minerals.[4] The kingdom of minerals was later removed from taxonomy by Ernst Haeckel, leaving plants, animals, and the protists as a "kingdom of primitive forms".[5]Herbert Copeland resurrected Hogg's label almost a century later, arguing that "Protoctista" literally meant "first established beings", Copeland complained that Haeckel's term protista included anucleated microbes such as bacteria. Copeland's use of the term protoctista did not. In contrast, Copeland's term included nucleated eukaryotes such as diatoms, green algae and fungi.[6] This classification was the basis for Whittaker's later definition of Fungi, Animalia, Plantae and Protista as the four kingdoms of life.[7] The kingdom Protista was later modified to separate prokaryotes into the separate kingdom of Monera, leaving the protists as a group of eukaryotic microorganisms.[8] These five kingdoms remained the accepted classification until the development of molecular phylogenetics in the late 20th century, when it became apparent that neither protists nor monera were single groups of related organisms (they were not monophyletic groups).[9]Modern classificationsCurrently, the term protist is used to refer to unicellular eukaryotes that either exist as independent cells, or if they occur in colonies, do not show differentiation into tissues.[10] The term protozoa is used to refer to heterotrophic species of protists that do not form filaments. These terms are not used in current taxonomy, and are retained only as convenient ways to refer to these organisms. The taxonomy of protists is still changing. Newer classifications attempt to present monophyletic groups based on ultrastructure, biochemistry, and genetics. Because the protists as a whole are paraphyletic, such systems often split up or abandon the kingdom, instead treating the protist groups as separate lines of eukaryotes. The recent scheme by Adl et al. (2005)[10] is an example that does not bother with formal ranks (phylum, class, etc.) and instead lists organisms in hierarchical lists. This is intended to make the classification more stable in the long term and easier to update. Some of the main groups of protists, which may be treated as phyla, are listed in the taxobox at right.[11] Many are thought to be monophyletic, though there is still uncertainty. For instance, the excavates are probably not monophyletic and the chromalveolates are probably only monophyletic if the haptophytes and cryptomonads are excluded.

What is the largest classification?

The largest classification in the biological hierarchy is the domain. There are three domains: Bacteria, Archaea, and Eukarya. Eukarya includes organisms such as plants, animals, fungi, and protists.


What kingdom is influenza in?

Viruses are classified differently than living organisms, since they are not technically alive. In taxonomy, viruses are not assigned to a Domain, Kingdom, Phylum, Class, or Order. The influenza viruses start, in most classification systems, at the level of the Family. They are in the Family of Orthomyxoviridae. There are a few newer classification systems that have been developed to better categorize and classify viruses, but these are not yet the standard.

Why do you think that Protista is often called the odds and ends kingdom?

Because it is hard to classify in a taxonomic fashion. Cladists have a very hard time finding the evolutionary relationship in this kingdom and other means of classification are just as stumped. With the newer molecular methods perhaps scientists will get a handle on the taxonomy of this kingdom.


Are newer exhaust systems designed to reduce more pollution or have they stayed the same over the years?

Yes, newer exhaust systems are being designed to reduce more pollution and simultaneously boost engine performance. One of the newest systems is designed as a single unit rather than a unit comprised of multiple parts. Newer exhaust systems have gotten more enviromentally friendly. They claim to reduce the emissions being put out. Proper maintenance of the car will also help keep our air clean.
