Hexapods Are a Diverse Group of Six-Legged Arthropods

Hexapods Are a Diverse Group of Six-Legged Arthropods Hexapods are a group of arthropods that include more than one million described, species, most of which are insects, but a handful of which belong to the lesser-known group Entognatha. In terms of the sheer number of species, no other family of animals comes close to the hexapods; these six-legged arthropods are, in fact, over twice as diverse as all other vertebrate and invertebrate animals combined. Most hexapods are terrestrial animals, but there are some exceptions to this rule. Some species live in aquatic freshwater habitats such as lakes, wetlands, and rivers, while others inhabit coastal marine waters. Hexapods Avoid Sub-Tidal Marine Areas The only habitats that hexapods avoid are sub-tidal marine areas, such as oceans and shallow seas. The success of hexapods in colonizing land can be attributed to their body plan (especially the strong cuticles covering their bodies that provide protection from predators, infection and water loss), as well as their flying skills. Another successful attribute of hexapods is their  holometabolous development, a mouthful of a term which means that juvenile and adult hexapods of the same species are very different in their ecological requirements, immature hexapods using different resources (including food sources and habitat features) than the adults of the same species. Hexapods Are Vital But Also Pose Many Threats Hexapods are vital to the communities in which they live; for example, early two-thirds of all flowering plant species rely on hexapods for pollination. Yet hexapods also pose many threats. These small arthropods can inflict vast crop damage and are known to spread numerous debilitating and fatal diseases in humans and other animals. The body of a hexapod is made up of three sections, a head, a thorax, and an abdomen. The head has a pair of compound  eyes, a pair of antennae, and numerous mouthparts (such as mandibles, labrum, maxilla, and labium). The Three Segments of Thorax The thorax consists of three segments, the prothorax, the mesothorax, and the metathorax. Each segment of the thorax has a pair of legs, making for six legs in all (the forelegs, the middle legs, and the hind legs). Most adult insects also possess two pairs of wings; the forewings are located on the mesothorax and the hind-wings are attached to the metathorax. Wingless Hexapods Although most adult hexapods have wings, some species are wingless throughout their life cycles or lose their wings after a certain period before adulthood. For example, parasitic insect orders such as lice and fleas no longer have wings (although their ancestors of millions of years ago did have wings). Other groups, such as the Entognatha and Zygentoma, are more primitive than classic insects; not even the ancestors of these animals had wings. Many hexapods have evolved alongside plants in a process known as coevolution. Pollination is one example of a coevolutionary adaptation between plants and pollinators in which both parties benefit. Classification Hexapods are classified within the following taxonomic hierarchy: Animals Invertebrates Arthropods Hexapods Hexapods are divided into the following basic groups: Insects (Insecta) - There are more than one million species of insects that have been identified, and scientists estimate that there may be many millions more species yet to be named. Insects have three pairs of legs, two pairs of wings and compound eyes.Springtails and their relatives (Entognatha) - The mouthparts of springtails, such as the two-pronged bristletails and the proturans (or coneheads), can be retracted within their heads. All entognaths lack wings. Edited on February 10, 2017, by Bob Strauss

The Cedarville County jail

The Cedarville County jail Introduction The Cedarville county jail is an incarceration facility that has recently been built and it is equipped with the modern technology in security.Advertising We will write a custom essay sample on The Cedarville County jail specifically for you for only $16.05 $11/page Learn More Although this incarceration facility has an upper hand when it comes to security, it is also faced numerous problems ranging from security within the facility, administration management in terms of finance and issues of drug, alcohol and morale that have engulfed the employees within the Cedarville County jail. As the newly appointed CEO to the Cedarville County jail, my main objective is to make use of the existing security technology to deal with the insecurity issues and transform the administration of the facility by tackling head-on the issues engulfing it. Strengths One of the dominant strength of the Cedarville County jail is its latest and modern technology in secu rity. The latest technology in security, if fully exploited, will play a major role in ensuring that inmates’ presence is limited to within the confines of the facility. The Cedarville County jail facility will also attain another advantage of an experienced administrative team that has previously worked together. The separation of the adult and juvenile offenders is a strength that comes into good use especially while addressing the different issues facing the two sectors of the facility. This is because the issues facing adult offenders’ facility are different from the issues facing the juvenile facility. Weaknesses One of the major weaknesses that are evident in the Cedarville County jail is the indulgence of its employees in drugs and alcohol. This kind of behavior portrays a negative image of the jail which is meant to be a correctional facility. The poor financial and accounting system of the facility is also a weakness set to affect the operations of the facilit y. Gender equality within the administrative posts is a weakness that needs to be looked at as women are said to be employed in the lower ranks of administration posts. Opportunities The main beneficial opportunity to the Cedarville County jail is the willingness of the county government to assist the facility with funds and additional resources. This is an opportunity if put to good use, will ensure the transformation process of the facility is successful. Working with the strategic management team that I have previously worked with is a golden opportunity and a boost to the efforts of transforming the facility. Threats The low morale among the facility’s employees is a serious threat that if not properly tackled, it may lead to the failure of the transformational efforts about to be undertaken. In additional to this the lack of technical knowhow among the officers in using safety and restraint technique is a serious threat that is posed to the security of the entire facilit y. Without proper training of the officers, the transformation efforts of the facility will be null and void.Advertising Looking for essay on business economics? Let's see if we can help you!

Strengthening and emphasizing of these strengths and opportunities and at the same time tackling of the weaknesses and threats will enable the facility and its administration to attain the set objectives. Making good use of the latest technology in the facility’s security system will be a move that exploits the strength of the Cedarville County jail facility while at the same time the existing security menace within the facility will have been tackled.

Analysis movie Mr. and Mrs. Smith Essay Example | Topics and Well Written Essays - 1750 words

Analysis movie Mr. and Mrs. Smith - Essay Example The two-hour movie depicts a modern setting. The lifestyles of the character and the type of guns used by both the couple and the attackers suggest the movie was set to represent 21st-century technology. The gunfire and destruction of properties by couples and the attackers create an illusion that presents the movie as being based on future technologies. The intelligent couples represent the ideas of the movie writers. The movie is then divided into three sections. Jane and John are used to highlighting the three sections. Romance, revenge and reverse attacks are the three parts describing the movie. The movie is able to unite the three components and suggest use of high technology in both the house settings and the outdoor setting. The indoor setting targets romance and suspicion while the external setting indicates clam and waves of attacks from previous employees. The director fails to address the Space factor as a larger amount of time is allocated to John and Jane setting with f lashback being ignored (Liman, 2005). Acting and Drama The movie depicts sexual scenes and many scenes of violence. The couples (John and Jane) are the only characters in the movie that exhibits romance. The onset actors tend to force more on violence rather than the diversity of the film. The couple begins and ends with romance. In an effort to break the monotony, the film takes a twist and allows elements of violence and suspicion. The actor presents a fictional story and action thus lacking realism.
