Invasive Species Essay

Many things live in your mouth. Bacteria live in it. You ask, “What kinds of bacteria? Why can’t we sense it? Is it good or bad?” Be brave, take a reading adventure and find out answers to all these questions, and more. How much bacteria exactly? A lot of bacteria live in your mouth, colonies, and colonies. About 6 billion live in your mouth. That’s interesting because about 7.3 billion people live on earth. All those bacteria that live in your mouth actually live in diverse communities,…

removed of technology, this species would not have survived as long as we have: since we do not have much hair, we would have frozen to death because there would have been no way to create and keep a fire going to warm us up enough to stay alive and keep predators away. If there was an encounter with a predator, the predator would have most likely prevailed due to our inferiority in strength and speed. The aid of technology has made us evolve into the smartest species dominating the earth. As we…

Tullis, Paul. "When You Walk Into a Zoo, Are You Helping Animals or Hurting Them?" TakePart. N.p., 02 May 2014. Web. 16 May 2017. . Paul Tullis, an editor at TakePart and writer for the New York Times Magazine, tries to answer the question “When you walk into a zoo, are you helping animals or hurting them?” Tullis covers many different topics and stories throughout his article providing evidence that zoos are helping animals along with zoos not helping them. Tullis believes his…

John Endler conducted two studies documenting the relationship between guppy coloration patterns in correlation to predation and sexual selection. Endler (1980) references his previous field study (Endler, 1978) in regards to coloration patterns present in the presence and absence of different predators. The relationship that was found there (Endler, 1978) was that in areas of high predation, coloring was less conspicuous and more closely blended to their background, whereas in areas of low…

with other organisms. A result of natural selection is an increase of offspring, which leads to an increase in the population of specific species.…

As they approached the beach, they saw the purple flags and no swimming signs. They asked the lifeguard why the purple fag was up, and the lifeguard said one word, “jellyfish.” Jellyfish can paralyze and kill other small animals, and sometimes they kill humans. Most jellyfish are transparent and have very long tentacles. These are good qualities for a predator. However, now you can buy anti-jellyfish sunscreen. Many cultures cook and eat jellyfish, and we are using them in medical research.…

Likdisha AP Biology Essay #2 The modern synthesis incorporated Charles Darwin’s theory of natural selection and many other fields of science, including genetics, to explain evolution more accurately. When Darwin wrote “On the Origin of Species “, he only explained the first mechanism of evolution, which was natural selection. The modern theory of evolution now highlights three more important mechanisms for evolution, which are mutations, genetic drift, and gene flow. Many fields…

Microevolution “Microevolution is evolution on a small scale, within a [shared gene pool] population” (Berkeley 2006). The shared gene pool experiences genetic changes that can create differences within a species. These genetic differences are inherited from one or both parents. Genes are either lost or combined differently and can result in things such as different hair color, longer legs or bigger ears. There are four processes that contribute to microevolution: 1. Mutation – a physical…

What are the traits that are unique to primates and enable them to be well suited to an arboreal environment? Ability to adapt to new or changing circumstances, live almost anywhere; they inhabit many different landscapes and climates. With that, they have a variety of traits that enable them to live in arboreal environments. The overall bone structure gives primates great flexibility and long limb allows them to swing from tree to tree easily. Having dermal ridges on the hands and feet is…

Bryan Vongkhamdy Articulation of Human Hands in Comparison to Bear Paws Chimpanzees, apes, and gorilla share a very similar anatomy but another mammal also shares a similar anatomy to humans as well. The bear in particular also shares a similar anatomy, specifically the paws of a bear when compared to a human’s hands. Even with similar anatomy, the bear is mostly a quadruped mammal, but is capable of bipedalism, while humans are bipedal mammals. In humans, the hand is meant for a variety of…
