Five extinctions of Earth and Who will be Next? The Earth we live on now is drastically different from how it was millions of years ago. The Earth has gone through many changes and events though time. There are five major events in history that have changed the world. Without these five mass extinctions who knows what Earth would have looked like, and if humans would even be alive. In the ordovician period 439 million years ago there was a mass extinction that wiped out 89% of life on Earth.…

In 1845, Frederick Douglass wrote his astounding novel entitled “Narrative of the Life of Frederick Douglass, an American Slave”. This text was revolutionary at the time, with a message for both slaves unknown to the freedoms of the world, and slave owners questioning the morality of slavery. His purpose was to educate, it was to prove himself in the eyes of all who doubted the intelligence of a black man. For slaves, it was to inspire to rise up, to grow and educate themselves. For slave owners…

opinions on whether cloning is right or wrong. In 1885, the first practice of cloning begun when Hans Adolf Edward Dreisch proved it was not just a dream by demonstrating cloning by simply shaking two-celled sea urchin embryos, separating the cells into two totally different sea urchins. Since then cloning has been taken even further…

One type of sediment to note is diatomaceous earth, an uplifted siliceous ooze which contains the remains of the microscopic algae known as diatoms (Garrison and Ellis 152). With a density lower than most other sediments—measured at 0.2816 g/ml in our lab results—the powdery and apparently sticky sediment has rather tiny grains as expected from this sort of sediment. As diatomaceous earth derives from the diatom ooze of the deep ocean floor, it originates from the slow dissolution of diatom…

My mom always asked me, “If your friends jump off a cliff, would you jump too?” Evidently, I would. As I was falling off the End of the World, I realized what a stupid idea it was. No, not the actual end of the world, but a cliff that lives up to its name. I plunged into the ocean, salt water rushed into my nose, and I struggled to catch my breath. While clinging onto a rock for dear life, I had another realization; my mother would never let me do this. In the early years of my childhood I lived…

landmass' frigid ocean will have sufficiently warmed (by around 1.8 degrees Fahrenheit, or 1 degree Celsius) to permit these titan crabs to move up onto the rack and begin eating up the echinoderms (a gathering that incorporates ocean stars and ocean urchins) and mollusks, (for example, shellfishes and mussels) that live there. "That is the thing that must concerned — that in the event that they get up onto the mainland rack they will draw down those populaces that have lived in segregation…

Kids and adults today don’t care as much for an education like Keller and Douglass did in these stories. Keller and Douglass wanted to learn so badly that they went through the struggles that they had to. Hellen Keller was a blind and deaf woman and Fredrick Douglass was an African American slave that was not allowed to learn. Both "The Story of My Life" and "Narrative or the Life of Fredrick Douglas, an American Slave" share the central idea that education is worth the struggle they had to go…

The book, Coral Reefs, by Simon Rose, presents that categories of coral reefs, what coral reefs are home to, and the dangers that they may face. Coral reefs are made up of coral polyps that attach and multiply to a limestone skeleton called a calicle. Coral reefs are categorized in three ways, which is by their type. 1. Fringed reef, 2. Barrier reef, 3. Atolls. The fringed reef either borderers the shore near a lagoon, or it will be directly attached, next is the barrier reef. The barrier reef,…

Douglass a firsthand experience of slavery with being a former slave. Knowledge was influential to him and he states that, “This bread I used to bestow upon the hungry little urchins, who, in return, would give me that more valuable bread of knowledge”(49). In this, he values education and his knowledge as power. Douglass also would read arguments that were against slavery and would realize how wrong and evil the society is. This…
