What Good Are Ticks 3 Reasons to Tolerate Ticks

There may be no â€Å"bug† creepier than a tick. These blood-sucking parasites can crawl up your body, embed their mouthparts in your skin, and then casually drink their fill of your blood until their bodies expand like tiny water balloons. Ticks carry and transmit a variety of diseases to people and pets, from Lyme disease to anaplasmosis. Feeding ticks can paralyze livestock, and large tick infestations can kill the host animal. So as you carefully pluck a tick from your skin, you may undoubtedly wonder what purpose they serve.   Ancient Arthropods Though it might be hard to see from the perspective as a blood host, ticks do serve an important role in the ecological system. Every organism serves a purpose, and the lowly tick is no exception. Parasitic ticks first appeared in the fossil record during the Cretaceous period, and it’s believed they were the bane of dinosaurs millions of years before they bothered humans. The oldest known fossil tick was discovered in a piece of amber recovered from a vacant lot in Sayreville, N.J. Carlos Jerseyi, as the specimen was named, is 90 million years old and may have come to North America by hitching a ride with a seabird that migrated from South America. Despised though they might be, ticks are clearly doing something right to have survived this long. Reasons to Tolerate Ticks Ticks are food for other animals. Reptiles, amphibians, and birds all consume a large number of ticks. The arachnids are an essential food source for animals that forage for sustenance in the places where ticks live—which is almost everywhere. In areas that are thick with ticks, people will sometimes deploy guinea hens as a roaming tick-control team. And the neighborhood  opossums that wander through your yard after dark are doing their part, too. Opossums eat a remarkable number of ticks. Ticks host a variety of other organisms, namely microparasites. Ticks carry viruses, bacteria, protozoa, and other microscopic life wherever they go. While you may prefer that they didn’t, since many of these stowaways are the very source of human tick-borne illnesses, in the grand, ecological scheme of things, these microorganisms are part of the diversity of life on Earth. Control Populations By virtue of their blood-draining, disease-causing ways, ticks help control the populations of their larger hosts. People understand concepts like carrying capacity and population control when they consider predator-prey relationships, but they are less sympathetic to the tiny parasites that serve the same purpose. Just as the owl keeps the population of mice and shrews in check, ticks play a role in maintaining a balance within the ecosystem. Regardless of whether the giraffe is taken down by a lion or blood-draining feast of 50,000 ticks—and that is the record for the number of ticks on a single, small ​giraffe—t’s still one less giraffe in the herd. Ticks are just doing what they’ve been doing for tens of millions of years. If you don’t want them feeding on you, be sure to take precautions to avoid tick bites.

American History Slavery - 910 Words

Slavery (APA) American History Slavery (Order #A2094863) Question #1 In the first half of the 19th century the Untied States quickly expanded westward, but as the country grew the expansion of slavery became a hotly contended issue. Those states that already allowed slavery, mostly the South, wanted to expand the institution into newly established territories and states, while non-slave states in the North wanted to curtail it. In response, a series of compromises were reached in Congress where each new non-slave state admitted to the Union was balanced by a new slave state. This balance maintained the peace between pro-slavery and non-slave states for most of the first half of the 1800s. But as both sides continued to compromise over the issue of slavery, radical splinter groups began to emerge on both sides which sought to disrupt the compromises. The Southern states, which relied on slavery for the continuation of their plantation system, argued that the expansion of slavery into new territories was critical for the nations economy. In spite of the economic advantages for the wealthy, many Southerners claimed that slavery promised the common man great wealth. (Schultz, 2011, p.234) In the North, however, there were different reasons for opposing the expansion of slavery.

Colin Poole (2239 words) Essay Colin Poole HIST 308 First Paper Throughout the Antebellum era,one issue that large in part contributed to the political and social climate of the era was the issue of slavery in the United States. This would be the subject of bitter debate over the years,culminating in the American Civil War. Before that,numerous writers and orators,both black and white,wrote and spoke on the issue,some with more moderate,peaceful views,and some with more militant,at times violent views regarding the issue of slavery. One of the more peaceful voices of the discussion was Frederick Douglass. Born into slavery,Douglass escaped his enslavement in Maryland as a young man. Upon arriving in New York,he married Anne Murray,and theysettled in New Bedford,MA to begin their life together. As Douglass became older,he became a prominent voice of the abolitionist,becoming a leader in both New York and Massachusetts. Douglass quickly became famous for incredible talent for oration,and for his passion and measure in fighting slavery. Regarded as perhaps the most prominent black abolitionist of his day,Frederick Douglass impacted the abolitionist movement and societys view of black Americans ina remarkable,reverberating way,and redefined the way American slavery literature was written. Frederick Douglass began writing and speaking during a time when the division within the Union was prominent for all to see.At this time,Douglass had a heavy hand in bringing attention to the debate of slavery.Douglass accomplished muchthroughout his life.Born aslave in 1817in Maryland,heeducated himself and became determined to escape the atrocities of slavery.Douglassattempted to escape slavery once,but failed.He later made hissuccessful escape in 1838.After settling in New Bedford,Douglasss abolitionist careerbegan at an antislavery convention at Nantucket,Massachusetts.Here,he first demonstrated his skills as a powerful and eloquent orator.Douglass became involved with many importantabolitionistcauses,through his literary works,through his work with theUndergroundRailroad (Aptheker, 1989).Due to theincreasing stringency of fugitive slave laws,Douglass found himselfin danger ofbeing captured and returned to slavery.To avoid this,he left America,and stayed in the British Isles.The re he lectured on slavery,and found similar popularity among abolition-minded British people. Some of these peopleraised money topurchase his freedom.In 1847,Douglass relocated to Rochester,New York,and becamethe person in charge of the Underground Railroad.Here he also began the abolitionistnewspaper North Star,which he edited until 1860(Bowers, 2010). During this period,Douglass became friends with another well-known Americanabolitionist,John Brown.Brown was involved with the Underground Railroad,and laterwanted Douglass to join him on terroristic attacks on a United States government arsenalat Harpers Ferry.Douglass declined to participate in such activities.In the aftermath of John Browns attack on Harpers Ferry,Douglass fled for a time to Canada,fearing that his association with John Brown could threaten him.He returnedafter several months,and supported AbrahamLincolns campaign for president.FrederickDouglass remained a prominent figure of black abolitionismbefore dying in 1895,inWashington,D.C(Aptheker, 1989). Frederick Douglasss life as a slavenaturallyhad the greatest impact on his writings.With his experiences,Douglasss experience as a former slave allowed him to paint a rather vivid picture for his audiences the cruelty the life of a slave was fraught with.Douglass recounted cruel instances ofwhippings,inadequate meals,and other harshtreatmentin a detailed way.His thirst for freedom,and his burning hatred of slavery caused him to writeNarrative Of The Life Of Frederick Douglass,and other similarworks.InhisNarrative,Douglass wrote the complete story of his miserablelife as a slave and his strife to obtain freedom.Douglasss youthful motivationwas to make it through another day so that someday he might seefreedomeventually.This would,unsurprisingly,become the subject of Douglasss writings. While these books all start with Douglasscoping with slavery,though as he was noted for his strong communication skills his writings served another purpose.As acommittedabolitionist,Douglass presented the brutality and inhumanity of slavery in an eloquent,urgent,and convincing way.Through telling his story,he won the hearts and minds of many who found themselves disgusted by the abhorrent institution of human enslavement(McFeely, 2011).

Sex Who Needs It Essays - Sexual Acts, Fertility,

Sex Who Needs It annon Ive found the past couple of years to be an eye opener in the world of sexual experiences. Im not necessarily referring to my own experiences, but those of society in general. There was a time when more smart-conscious decisions were made relating to sexual relationships. But times have changed. The pillars that hold up our individual sexual values have started to crumble. No longer can we create our own standards without feeling ostracized by the society that forms the standards for us. With influences coming from the media, infatuated hormones and opinionated peers, teenagers today have turned the act of love making into a whimsical joyride. The difference between making love and having sex is miles apart. To make love, the partners involved use their hearts more so than their parts. To have sex, the partners use their parts more so than their hearts. The key to this Dr. Seuss rhyme lies in the selected noun that the partners use in their actions. Since hormones and feelings (hearts) both exist on a different level, saying that they are the same would be to take away all the feeling, emotion and love involved in love making. Teens are letting their hormones control their sexual decisions by giving in to the pure pleasure of sex. To make up for their lack of solid reasoning behind their acts, they try to rationalize their choices. The justification that many couples come up with for having sex is love. I cant help but wonder how many couples would actually stay together if their relationship existed without sex. Friends and peers are a big pressure factor when deciding weather or not to have sex. As seen in many after school specials, the popular Cmon, everybody is doing it, isnt far off the mark. Just knowing that three or four other couples in a social group are having sex can sway a couple to give in and start hitting their own home runs on their sexual playing field. With each new couple having sex, the pressure current becomes stronger and stronger, especially for those couples not sexually active. At this point many couples get swept in the flow of the current and just go with it; they do the nasty. Once theyve committed themselves to having sex, its very hard to stop. The couple might find out that they arent ready for this big step in their relationship, but to stop having sex would mean to lose face with friends! Well, do you think that theyre going to stop having sex? Not a chance! And, so they continue their acts of whimsical joyriding, without any care to see where the ride is taking them, just to keep their status with their social group. The media is also a persuasive factor that plays a large role in the life of a teenager. Although t.v. shows, films and magazines are all supposed to offer escape from reality, many teens buy into the situations presented as if they were real. For instance, how many teens watch Beverly Hills, 90210? Now, heres a show that says to kids straight out, Its o.k. to have casual sex and not think of any consequences. The writers even took the only virgin on the show, Donna, who remained true to her faith for so long, and had her give up her virginity. The one thing the writers failed to look at however, is the number of youth that watch the show, and in that number, how many take the ideals of the show and use them as their own personal values. All of the characters on 90210, the most popular teen show on t.v., have casual sex. Teens who watch the show are going to take this into account when they have their own sexual experiences. The love and care given/received in a teenagers 90210 relationship can only reflect the fake morals seen on-screen. The reality of consequence is the fastest wake-up call anyone can have given to them. One needs not carry a glass ball around with them to predict the future. All it takes is being able to visualize the repercussions of their actions. Now, I know that every teenager has been taught in health class how the sexual reproduction system of a human works: the little male spermy-wormy goes for a swim up the canal and fertilizes the little female egg-weggy. So, I am dumbfounded when a couple that has had unprotected sex is shocked when they find out theyre expecting. Well, Hell-oOo?!? Didnt you read the label on your penis,
