  1. Of the form

    In mathematics , the phrase of the form indicates that a mathematical object, or more frequently a collection of objects, follows a certain pattern of expression. It is frequently used to reduce the formality of Mathematical proof mathematical proofs . Example of use Here is a proof which should be appreciable with limited mathematical background Statement The product of any two Even and odd numbers even natural numbers is also even. Proof Any even natural number is of the form 2n , where n is any natural number. Therefore, let us assume that we have two even numbers which we will denote by 2k and 2l . Their product is 2k 2l 4 kl 2 2kl . Since 2kl is also a natural number, the product is even. Note In this case, both Proof by exhaustion exhaustivity and Exclusive exclusivity were needed. That is, it was not only necessary that every even number is of the form 2n exhaustivity , but also that every expression of the form 2n is an even number exclusivity . This will not be the case in every proof, but normally, at least exhaustivity is implied by the phrase of the form .

    Unreferenced date September 2008 Invertebrate zoology is the biology biological academic discipline discipline that consists of the study of invertebrate animals, i.e. animals without a vertebral column backbone a structure which is found only in fish , amphibian s, reptile s, bird s and mammal s. Invertebrates are a vast and very diverse group of animals that includes sponges , echinoderm s, tunicate s, numerous different phylum phyla of worms, mollusc s, arthropod s and many additional phyla. Single celled organisms or protist s are usually not included within the same group as invertebrates. Invertebrates are 97 of all named animal species , and because of that fact, this subdivision of zoology has many further subdivisions, including but not limited to Arthropodology the study of arthropods , which includes Arachnology the study of spiders and other arachnid s Entomology the study of insect s Carcinology the study of crustacean s Myriapodology the study of centipede s, millipede s, and other myriapod s Malacology the study of mollusk s Invertebrate paleontology the study of extinct invertebrates These divisions are sometimes further divided into more specific specialties. For example, within arachnology, acarology is the study of mite s and tick s within entomology, lepidoptery is the study of butterflies and moth s, and so on.

    unreferenced date November 2010 File Blue mussel clump.jpg thumb Blue mussels, Mytilus edulis , are sessile and exhibit clumping. In zoology , sessility is a characteristic of animal s which are not able to move about. They are usually permanently attached to a solid substrate biology substrate of some kind, such as a rock geology rock , or the Hull watercraft hull of a ship in the case of barnacle s. Coral s lay down their own substrate. Sessile animals typically have a motile phase in their development. Sponge s have a motility motile larval stage, which becomes sessile at maturity. In contrast, many jellyfish develop as sessile polyp s early in their life cycle. Many sessile animals, including sponges, coral s and hydra genus hydra , are capable of asexual reproduction in situ by the process of budding . Clumping is a behavior in an animal, usually sessile, in which individuals of a particular species group close to one another for beneficial purposes, and can be seen in coral reef s.
