INTRODUCTION On the 9th our Biology class went on a trip to Sirens Rock Wellington to investigate the organisms living at the rocky shore and their relationships with each other our task was to display information on the relationships between two species we discovered at the Rocky Shore we then use this information to form a report and explain the species and their relationship with one another, but before this we need to understand the definition of zonation; zonation is the distribution of…

Chapter 01: Introduction 1.1. Xenobiotics The term xenobiotic is derived from Greek words, “xenos”, meaning strange or foreign, and “bios”, meaning life. Thus xenobiotics are exogenous chemicals which includes natural and synthetic chemicals. These can be pesticides, chemical vapors from automobiles, industrial chemicals, plastics, secondary plant metabolites, toxins produced by plants, molds and animals, food additives etc. Xenobiotics are considered as pollutants, but all the pollutants are…

Justin Dubler August 31, 2015 Mrs. Werle Period #1-2 AP Biology Summer Assignment Survival of the Sickest Big Idea 1: The process of evolution drives the diversity and unit of life. Passage 1: “Our genetic makeup has been adapting in response to where we live and what the weather’s like. The food we eat has evolved to cope with the organisms that eat it, and we’ve evolved to cope with that. We’ve looked at the way we’ve evolved to resist or manage the threat posed by specific infectious diseases…

While there is a belief that humans have evolved from apes, religion has an explanation. Evolution is the theory that modern life has descended from a common ancestor, through the process of natural selection. Faith on the other hand, claims that life was created in the form it is today with some alterations from God. Since evolution was found it has been debated by all faiths. Evolution generates an explanation for the origin of life which is not necessary when there is religion, logic, and…

What is Evolution? Many people believe that evolution is the answer to the question where life came from. This, however, is a complete misunderstanding of the actual origin of the word. The term evolution comes from Latin and literally means “the change in the gene pool of a population from generation to generation by [undergoing] different processes” (“Evolution”). This theory of evolution specifies only on the question about how life arrived at the point it has, not about the origin of life…

Charles Darwin was a renowned English naturalist and geologist that has since been described as one of the most prominent figures in both scientific and human history. He was best known for his compelling theories and contribution to evolution and is now considered the founder of Biological/Physical anthropology. Darwin was born on February 12, 1809, in Shrewsbury, England. He was born into wealth and power as he was part of a long line of scientists and doctors, which included his father,…

Charles Darwin: Observations and Struggles Everyone has heard of Charles Darwin; he was a scientist and naturalist and to some people the most important scientist of modern times. He is best known for introducing the theory of evolution based on natural selection. His most famous book, and the one that introduced this theory, is On the Origin of Species. A big thing that influenced his decision to write this book was his voyage on The Beagle, especially his trip to the Galapagos Islands.…

Evolution is a change in populations over time. It is the population that evolves, rather than an individual. There are four mechanisms of evolution: mutation, gene flow, genetic drift, and natural selection. There were multiple contributors to the ideas of evolution, including Charles Darwin and Alfred Wallace. To begin with, mutations cause genetic variation. Genetic variations are the differences in DNA sequences. The differences in DNA sequences caused by mutations are known as alleles…

Bawazer relate to Bronowski’s belief about science as imaginative and creative? We will find out if this bond between James Bronowski his notion of the nature of scientific reasoning and Luke Bawazer comparing to Edward Wilsons theory of intelligent evolution. Jacob Bronowski (2012) writes about Copernicus’s route to enlightenment as an obscure theorist challenging the common science of his time, his first stage was his mind to raise him from the planet, and put him enthusiastically,…
