Consecutive Numbers :: Papers

Consecutive Numbers Task 1 Problem 1 Write down 3 consecutive numbers. Square the middle one. Multiply the first and the third number. Compare the two numbers, what do you notice? Problem 2 ========= Write down two consecutive numbers. Square both of the numbers and find the difference between the squares. What do you notice? Problem 1 ========= I am going to investigate several sets of three consecutive numbers to see if the square of the middle is related to the product of the outer two numbers in any way. 9,10,11 10Â ²= 100 9x11= 99 3,4,5 I notice that the square of the middle number is always one more than the product of the other numbers. 4Â ²=16 3x5=15 18,19,20 19Â ²=361 18x20=360 1,2,3 2Â ²=4 1x3=3 30,31,32 31Â ²=961 30x32=960 1st Number 2nd Number 3rd Number 2nd number squared 1st number x 3rd number 9 10 11 100 99 3 4 5 16 15 18 19 20 361 360 1 2 3 4 3 30 31 32 961 960 I have put my results in a table so that they will be easier to analyse and compare. When you take three consecutive numbers, square the middle and multiply the outer two, the squared number will always be one more than the product of the outer two. If this rule is correct, then by using the three consecutive numbers: 101,102,103, I predict that 102Â ² will equal one more than 101x103. 101,102,103 102Â ²=10404 101x103= 10403 My prediction was correct as 102Â ², 10404, is one more than 101x103, 10403.

Botfly Facts and Tips for Removal

The botfly is a type of parasitic fly, best-known for disturbing images of its larval stage in skin and horror stories of infested people. The botfly is any fly from the family Oestridae. The flies are obligate internal mammalian parasites, which means they cant complete their life cycle unless the larvae have a suitable host. The only species of botfly that parasitizes humans is Dermatobia hominis. Like many species of botfly, Dermatobia grows within the skin. However, there are other species that grow within the hosts gut. Fast Facts: Botfly Common Name: Botfly or Bot FlyScientific Name: Family OestridaeAlso Known As: Warble flies, gadflies, heel fliesDistinguishing Features: Hairy fly with a metallic bot appearance. Infestation is characterized by an irritated bump, with a hole in the center for the larval breathing tube. Movement may sometimes be felt within the lump.Size: 12 to 19 mm (Dermatobia hominis)Diet: Larvae require mammalian flesh. Adults do not eat.Lifespan: 20 to 60 days after hatching (Dermatobia hominis)Habitat: The human bot fly lives primarily in Central and South America. Other botfly species are found worldwide.Conservation Status: Not evaluatedKingdom: AnimaliaPhylum: ArthropodaClass: InsectaOrder: DipteraFamily: OestroidaeFun Fact: Botfly larvae are edible and are said to taste like milk. How to Recognize a Botfly With its hairy, striped body, you could say a botfly looks like a cross between a bumblebee and a house fly. Othersv liken a botfly to a living bot or miniature flying robot, because the reflective hairs give the fly a metallic appearance. The human botfly, Dermatobia, has yellow and black bands, but other species have different coloration. The human botfly is about 12-19 mm in length, with hair and spines on its body. The adult lacks biting mouthparts and does not feed. In some species, botfly eggs are easily identified. For example, equine botflies lay eggs that resemble tiny drops of yellow paint on the horses coat. The fly is best known for its larval stage or maggot. Larvae that infest skin grow under the surface, but leave a small opening through which the maggot breathes. The larvae irritate skin, producing a swelling or warble. Dermatobia larvae have spines, which worsen the irritation. Bot fly larvae cause a lump with an open center, through which the breathing tube may be visible. Petruss Where Do Botflies Live? The human botfly lives in Mexico, Central America, and South America. People who live in other areas generally get infected while traveling. Other species of botfly are found across the globe, primarily (but not exclusively) in warm tropical and subtropical regions. These species infest pets, livestock, and wild animals. The Botfly Life Cycle Cuterebra sp. botfly larva extracted from the neck of a dead rabbit. Katja Schulz The bot fly life cycle always involves a mammalian host. Adult flies mate and then the female deposits up to 300 eggs. She may lay eggs directly on the host, but some animals are wary of botflies, so the flies have evolved to use intermediate vectors, including mosquitoes, houseflies, and ticks. If an intermediate is used, the female grasps it, rotates it, and attaches her eggs (under the wings, for flies and mosquitoes). When the botfly or its vector lands on a warm-blooded host, the increased temperature stimulates the eggs to drop onto the skin and burrow into it. The eggs hatch into larvae, which extend a breathing tube up through the skin to exchange oxygen and carbon dioxide. The larvae (instars) grow and molt, finally dropping from the host into the soil to form pupae and molt into adult flies. Some species do not develop in skin, but are ingested and burrow into the hosts intestine. This happens in animals that lick themselves or rub their nose on body parts. After several months to a year, the larvae pass through the feces to complete its maturation process. In most cases, bot flies do not kill their host. However, sometimes the irritation caused by the larvae leads to skin ulceration, which can result in infection and death. How to Remove Botfly Larvae Botfly larvae Hypoderma diana under a deers skin. Avalon_Studio / Getty Images Infestation with larval flies is termed myiasis. While its a characteristic of the botfly life cycle, it actually occurs with other types of flies, too. There are several methods used to remove fly larvae. The preferred method is to apply a topical anesthetic, slightly enlarge the opening for the mouthparts, and use forceps to remove the larvae. Other methods include: Using a venom extractor syringe from a first aid kit to suck the larvae from the skin.Oral dosing with the antiparasitic avermectin, which leads to spontaneous emergence of the larvae.Flooding the opening with iodine, which causes the fly to poke out of the hole, facilitating its removal.Applying the sap of the matatorsalo tree (found in Costa Rica), which kills the larvae, but does not remove it.Sealing the breathing hole with petroleum jelly, white glue mixed with insecticide, or nail polish, which suffocates the larvae. The hole is enlarged and the carcass is removed with forceps or tweezers.Applying adhesive tape to the breathing hole, which sticks to the mouthparts and pulls out the larvae when the tape is removed.Forcefully squeezing the warble from the base to push the larvae through the opening. Killing the larvae before removal, squeezing them out, or pulling them out with tape is not recommended because rupturing the larvae body can cause anaphylactic shock, make removal of the entire body more difficult, and increase chance of infection. How to Avoid a Botfly Infestation The easiest way to avoid getting infested with botflies is to avoid where they live. Since that isnt always practical, the next best tactic is to apply insect repellent to deter flies, as well as mosquitoes, wasps, and ticks that can carry fly eggs. Wearing a hat and clothing with long sleeves and pants helps to minimize exposed skin. Sources Felt, E.P. (1918). Caribou Warble Grubs Edible.
