or negatively that we forget the usefulness of stress response. To illustrate, the release of glucocorticoids could, in part, protect against other aspects of defensive systems. Moreover, ACTH (hormone involved on stress release) is also found in amphibians, reptiles, and insect, and they are usually associated with immune cells that set defensive processes in motion. If stress is so useful, it is reasonable for one to ask why it is not expressed all the time. There are few reasons for why its…

class Chrondrichthyes are cartilaginous fish found alongside the class, Actinopterygii, otherwise known as the bony fish, in various aquatic environments. The next several classes are more well known in basic science classes. Class Amphibia are amphibians known as the first creature to have limbs and now are commonly live near water. Class Reptilia evolved from the class Amphibia during the Carboniferous period and now primarily reside in warm dry climates. Classes Aves and Mammilia both evolved…

ago it became free of the ice. When Mount Rainier had been freed of the ice a short time later it had developed plant and animal life. Mount Rainier has about 182 species of birds, 14 species of native fish, 5 species of reptiles, 14 species of amphibians, and 65 species of mammals; invertebrates represent about 85% of the animal biomass in the park. It also has more than 890 vascular plants, more than 260 non vascular plants, and more than 100 exotic plants. Mount Rainier is a volcano that can…

Introduction Perhaps the most controversial principle of biology, this is due to many reasons ranging from the ignorance of the population to religious beliefs. I have chosen this principle as I wish to portray an unbiased look at this bold claim made by scientists where I present the facts in a scientific manner. So is there really any evidence that claim is true? Of course, we cannot tackle the entire tree of life at once, so instead, we’ll focus most of our attention on one small but…

Journalist, author, environmental activist, and founder of Friends of the Everglades, Marjory Stoneman Douglas, said in her book, The Everglades: River of Grass, “There are no other Everglades in the world. They are, they have always been, one of the unique regions of the earth; remote, never wholly known. Nothing anywhere else is like them…” (Douglas) The Everglades are located in the southern part of Florida. The Everglades National Park was established on December 6, 1947. The reason the park…

Creature from the Black Lagoon. In his essay, King describes the creature as being a “scaly, batrachian monster” and compares it to the ones created by H.P. Lovecraft, who is also an American horror author. While batrachian is defined as a tailless amphibian, such as a frog or a toad, when King uses this term, it almost sounds as if batrachian means prehistoric or ancient instead. The diction throughout his essay is what makes the monster sound terrifying, even if you have not seen the…

ancestor, or a close relative to an organism, they still helped the organisms we know today evolve and adapt to the environment that we now share. During the extinction events some species are more probable to survive than others are (Futuyma 173). Amphibians have survived through many of the great extinctions (Kolbert, 2009). They once were an all marine organism but have evolved throughout time and now can live on…

Captivity or Death Species reintroduction may sound great on paper as animals are brought back home to the wild and are once again happy. Humans are able to save endangered species and nurture the populations back from the brink. Injured animals have a safe haven in which to rehabilitate and thrive, then return to their family at home in the wild. Animals in animal testing are released from their suffering of being poked and prodded. In theory, this all sounds great, but in reality, one forgets…

During the field trip, which was held Thursday, February 22, I have made a lot of realizations. Throughout the field trip, numerous amounts of knowledge were gained. For example, I learned about the history of downtown Albany, Georgia. This included the renowned Flint River. I also learned how somewhere out there in the universe there could be more existing life. Making these new realizations there was some things that I was not to excited to learn about. For instance, I was well-informed that…

Big Idea 1: The process of evolution drives the diversity and unit of life. Passage 1: “There are two types of such cells: one is very sensitive to light, the other less so. The more sensitive cells record only in black and white; the less sensitive cells record in color. If we look around the animal world, we can assess whether animals are specialized for daylight or night by looking at the percentages of each type of light-sensing cell in their eyes.” (page 150) Enduring Understanding: 1.A:…
