What you Need to Know About Gypsy Moths By Mike Perri, The Davey Tree Expert Company Gypsy moth caterpillars defoliated thousands of trees in Toronto last year, creating a symphony of chomping and leaving behind a mess of droppings. To combat the infestation, the Toronto Urban Forestry staff implemented control measures in 2017. Because of their successful efforts, the city will focus on treating individual trees, instead of doing widespread aerial spraying, in 2018. But keep in mind that…

In this chapter, Darwin begins by how he is appalled by the lack of a defined term for species. He asks whether variation found in natural species can be analogous to similar variations found in the domesticated species. He relates this point by discussing domestication monstrosities involving pigs. Darwin defines monstrosities as variations that transpire in the natural world that are useless, and in some instances, inauspicious and harmful to the organism caused by reproduction creating…

Before one we can discuss some misconceptions about Evolution; we have to define the term first. Evolution is a process that is observed over time to see which different kinds of organisms have shown signs of development and diversified from earlier forms during the history of the earth. A few misconceptions that I have heard about evolution is one that my grandfather is always telling me; that us as humans are not letting natural take its course on us as humans, because we are always using…

The following piece of writing is a persuasive speech that will be presented in a seminar at aropened to the public, on organ donation. Presented by an organ donor recipient, who was able share their views today, all thanks a donation someone made, this speech may educate the community by covering facts, benefits and anecdote relating to organ donation. This persuasive speech will be directed to both females and male audiences (18+) in Australia, with the intend to persuade the them to see the…

I think that designer genes are morally wrong, except when it’s used to cure diseases. There are many reasons designer genes are wrong, and many unforeseen consequences. The majority of scientists think that customizing genes is wrong. You can’t just make “better people” using engineering (theoretically). In World War II, Adolf Hitler tried to make his own “Master Race”. He wanted to give everyone blonde hair and blue eyes by means of genetic engineering (O.I). Scientists in China…

The Spotted Wing Drosophila fly (SWD) is a quickly spreading across the United States of America. As SWD numbers get larger the number of fruit crops gets smaller. Aijun Zhang, a chemist working with the Agriculture Research Service, Invasive Insect Biocontrol, and the Behavior Laboratory in Beltsville Maryland, has found a solution to the SWD problem, Methyl benzoate. Methyl benzoate is emitted by snapdragons and petunias, to attract bees. SWD, unlike bees, is repelled from Methyl benzoate,…

Our group was assigned fruit flies with the mutated traits of shadow body and stubby wings. These traits were easily identifiable. A shadowed body was gray instead of the wild-type color of light brown, and stubby wings were nearly absent from the organism when they should be prominent. In this experiment, we attempted to determine the mode of inheritance for these two traits. After the parents mated, we viewed their F1 offspring. We noticed this generation didn’t contain either of the…

Finding species-specific markers within the genomes of organisms has proven to be an important practice in determining the dividing lines between species. Much of the subject of molecular genetics involves the determination of ancestry as well as common ancestry between species. Using molecular genetics, the concept of phylogenetic species has proven to be one of the more effective methods of differentiating between the species. For example, while other species classifier methods have had…

Traditionally, family members were defined as someone who was born into the family, adopted into the family, or united by marriage. Today’s family members have a broader spectrum which includes committed family households beyond legally married heterosexual couples and their children (McGoldrick & Carter, 2010). The complexities within each type of family structure were brought about by marriage, interracial coupling, foster parenting, informal kinship adoptions, social class position, and more.…

- Genetic testing is a medical assessment that detects any changes occurring in your genes, proteins or chromosomes. ("What Is Genetic Testing? - Genetics Home Reference." U.S. National Library of Medicine. National Institutes of Health, n.d. Web. 29 Nov. 2016.) - It is used to rule out any genetic condition as well as it can be used to determine a person’s chance of developing a genetic disorder. ("What Is Genetic Testing? - Genetics Home Reference." U.S. National Library of Medicine. National…
