Any cosmetic or medical companies will tell consumers that their products are the best since it has been tested on animals for safety, but the truth behind animal testing will make buyers think twice about their merchandise. Nowadays, more and more people are teaming up against animal testing. Laboratory testing is done on substances that make up medication and cosmetics, such as perfume, lotion, soap, etc. Animals are used to develop medical treatments, determine the toxicity of medications,…

ZO3017-Gerhand Schlosser Student Name: Claudia Speight Student Id: 13402132 The role of Modularity is important in evolutionary development The role of modularity is important in the developmental repatterning in evolutionary development. Organisms are composed of modules which are units of elements. Developmental modules serve as building blocks for evolution. They can been seen in heterotopy, heterochrony, heterometry, loss of modules and redeployment of modules. Here we will see…

World On The Turtle’s Back Analysis In the creational myth, “The World On The Turtle’s Back,” the Iroquois demonstrate the four functions of a myth: metaphysical (to instill awe), sociological (to support customs), cosmological (to explain the world), and pedagogical (to guide people). The Iroquois use these devices all throughout the story to tell their ideas on how the world began and what helped establish it. At the beginning of the story, a pregnant Sky woman falls from the Sky-World.…

species with similar niches and limited resources available. A niche is defined as an area that a species inhabits, the role or function of the species in the ecosystem and the species relationship with all is biotic and abiotic factors affecting it (Biology online dictionary, 2015).The limiting resources could be resources such as mates’ nutrients and space (M. Beals, L. Gross, S. Harrell, 1999). Competition exists between species with similar niches and limited resources because they are…

3. Results 3.1. Bumblebees We recorded a total of 98 bumblebee individuals (Bombus sp.) comprising 13 species (Appendix A, Table A.1). Sixty-four individuals belonging to 12 species were identified in managed meadows, and 34 individuals belonging to 8 species in abandoned meadows. Three of the total species were cuckoo bumblebees (Bombus [Psithyrus] sp). Five species were classified as long-tongued and 8 species as short-tongued. Total species richness and number of long-tongued species were…

In your own words describe Darwin's theory of evolution by natural selection. Charles Darwin is given the credit for bringing the theory of evolution is to the mainstream of modern science. this is why the evolution theory is sometimes called “Darwinism”. Charles Darwin was the youngest son of a wealthy physician. most of his life he was a lackluster student. door and dropped out of medical school, and enrolled at Cambridge University to study for the ministry. this was encouraged by his…

Are humans aware of the important role of more than one hundred thousands of genes that we have? I would say not all of us have. This question is not often ask unless we form part of a science club or have careers that are associated with biology, as a college student and future professional woman I do think it is important to ask this type of questions and to know the answer. People always tend to ignore the scientific side of the how our personality, behavior, temperament and experience…

Scientists learn about Earth’s history from rock layers, radiocarbon dating, and relative dating. The first way scientists learn about Earth's layers is by studying rock layers. Scientist discover fossils in different layers in the Earth and draw conclusions to the ones buried in the same layer to get an understanding of what kind of creatures were living in a time period. After studying the layers scientist also develop theories that turn into laws, for example the Law of Superposition states…

From both the article and the textbook, some of the unique qualities of humans are its bipedalism, large brain, complex language, and the ability to forge tools. Of all the traits listed above, bipedalism is one of the most vital. Not only was it essential for the survival and expansion of our species, but according to Darwin it is considered a key force for human evolution. (Ironically enough, one of the major health problems that people face today is living a sedentary life style.) Before we…

Each trust is like a step you must take to protect the animal kingdom. Through these trusts, a human’s cruelty can be transformed into compassion for all living beings. The authors want us to respect the interconnection through all living species. Every day humans harm the natural world more, without realizing the damage they are causing. The purpose of The Ten Trusts is to change your perspective on how we live on this planet. The authors want you to follow these trusts so the natural world…
