Aedes Aegypti
The mosquito that has attracted the most attention is the mosquito Aedes aegypti. It belongs to the family Culcidae, consisting of about 2,500 species
(Encyclopedia Britanica 1999), along with other genera of mosquitoes such as
Anopheles, Culex, Orthopodomyia, and the Toxorynchites, to name a few (Womack
1993, E.B. 1999). This mosquito has been known best for transmitting yellow fever and human dengue throughout the tropic and subtropic of the Americas (Womack, M 1993).
This mosquito along with others are looked upon as pests and nuisances in modern day society because of their attraction to moisture, lactic acid, carbon dioxide, body heat and movement (E.B. 1999) but we can not confuse the Aedes aegypti with any other mosquito for it has a very distinct look to it as well as a specific habitat. It has many related species and it’s geographic distribution is extremely wide and varied.
The Aedes aegypti, with regard to both sexes, are generally similar in coloration
(Womack 1993). The female adult is noticed by it’s small dark figure that is colored by white markings and banded legs. Its proboscis or snout is mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales present on the insect (Womack 1993,
Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for about three-quarters, and dark scaled for about two-thirds (Russel 1996).
The first through the fourth segments of the hind tarsi are characterized by white rings and the fifth segment is all white.
Adults can be found in abundance in towns and cities near human dwelling places., living in trees, herbaceous plants, dim closets, cabinets or even old automobile tires (Womack 1993, Juliano 1998). The species feeds mostly during the day increasing its feeding rate two hours after sunrise and several hours before sunset ( Womack
1993, Geographical Magazine 1998), while it is not rare for females to feed under artificial light at night. The above feeding habits of the Aedes aegypti contributes to the species’ life span which is dependent on nutrition, temperature and humidity (Womack
1993) as well as its ability to avoid predators such as reptiles or even sometimes other types of mosquitoes (E.B. 1999). The male mosquito can only live a short time ranging from a few days to a couple weeks whereas the female can live up to a month which allows her to reproduce longer (Womack 1993).
In the article “When Mosquitoes Were Killers in America” by Lauren Tarshis, She makes the statement “Yet mosquitoes are far more than a nuisance.” What she means is that mosquitoes aren't a little bug that just sucks a little blood and can be annoying, but instead it uses all that and more. Mosquitoes have killed millions upon millions of people by spreading disease like malaria. An example of how she supports this claim is in the article, she says “ In this way, bite by itchy bite, 212 million people are infected with malaria every year” (Tarshis 13). And that is only a year with bug spray, shots, and all the other things that help stop mosquitoes. So when the U.S. government tried to save people from these murders little insects. So they

There is a long history of single-sex schooling, in which males and females attend specific classes or schools only with members of their same sex. This separation of genders may be done for educational purposes or in combination with other factors, such as social interactions that occur between male and female students. There is some support for the idea that single-sex schooling can be beneficial, especially for outcomes related to academic achievement and more positive academic aspirations (Lee, 2008). Although, there are many benefits of children attending single-sex schools, evidence shows that sex segregation can also gender stereotyping and legitimizes institutional sexism (Kennedy, 2000).
Single Sex education supporters state that education will be “separate but equal”(Jackson, 2010). There are many reasons why this statement discriminates; history has shown us that this mind set has not worked before. This phrase is synonymous with oppression, segregation, and racism that took place in the south for decades. History has shown us that this is not the answer it is actually an infringement on equality. Single sex education feeds into many gender stereotypes. Single sex asserts that there are only two genders male and female and discounts people who are born intersex. Jackson states, “Because what counts as a standard male or female is subjective, there are no hard and fast numbers...
The reproductive system was mainly located towards the anal area and inferior to the stomach. The penis was located in the middle. It was white in color and looked like a mealworm. The seminal vesicles were located on both sides of the penis. They were grayish pink in color and looked like walnuts.
Throughout all the readings I looked at, Amy Novotney’s “Coed vs. Single-Sex Ed,” from the American Psychological Association happened to be the most useful. It was posted on February 1st, 2011, and it stated, “In 2006, at an all-male school, only four percent of the class could read at grade level, but later that year, in May to be exact, almost 100 percent of the senior class could read at different grade levels, and were being accepted into four-year colleges, or universities. Many of them were even on full academic scholarships. Thus, Single-Sex Education has been growing ever since.
The idea of single sex schools being more beneficial to students appeared in 1999 when studies showed that girls did better in math and science than boys (Niche
Imagine being a parent of a son or daughter and their being distracted by the opposite sex in class? Many parents like to believe that the opposite sex can be very distracting. The world should recognize that single gender schools can be more effective in several ways then coed schools can be.
The hornbill has a casque on top of its head, giving it its name. The casque is made of the same material of the bill itself. It is a black bird with a white stomach. The bottom of the wings are white as well. It has white around its eyes. The bird is typically 55-60 cm long. The male is 680-907 g in weight. Those are just a few of the characteristics of the hornbill.
The supporters of single-sex education believe that students are greatly interested in the educational process itself, not caring for their appearance or behavior. These types of schools help students acting freely without any motivations. Series of studies have proved that boys' and girls' brains are organized differently so each of them needs special treatment. Also each gender has its own privacy in joking and talking seriously. The scientists who support the theory of single sex education contribute their opinion religiously, saying that all religions call for separating both sexes as it is forbidden and against the religious teachings. They also think that mixing both genders inside any place is an evil deed that leads to committing sins that all religions forbid and say that there will be a severe punishment in the judgment day .While opposite opinions think that both sexes should exist together to grow up and learn how to be...
