areas thrushes feed mainly on a snail with dark shells with no light bands. In the forests they feed on snails with light band shells. These two different phenotypes each adapted to its environment. They are similar because they both lead to the evolution of a species to have certain traits. When given antibiotics some bacteria may be able to survive. Therefore the ones that survive can withstand the effects of the antibiotics. So if they are able to reproduce inside the person’s body (if a patient

continue to pass on those genes. Over time, more bacteria will contain DNA with genes allowing them to resist antibiotics and continue to reproduce. Because mutations do occur, it is possible to mutate genes to make them more or less fit for survival. Evolution / development does not occur in an

Round 1 = b. Round 2 = c. Round 3 = d. Round 4 = 2. Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = Action affecting Trees = Action affecting Flowers = Action affecting Bees = 3. Provide three specific actions that humans can take to minimize our impact on the ecosystem and ensure the survival of lichens, trees, flowers, and bees.

let me define the difference between extinct and threatened species; • Extinction is the process by which a species die out, this means that all genetic buildup of that species is gone forever. Extinction can be the cause of Natural disaster, from human activities. • Threatened species are living organism that can become endangered in our nearby future. Endangered species represent the living species of plants and animals. That have become scarce, this means that they are in danger

early 19th century) between Christian scientists and new theorists concerning how Earth came into being. In short, Christian scientists believe Earth was a process of divine creation; non-scientists believe Earth came about through a process of evolution (Mortenson, 2003). Article Strengths Mortenson did an excellent job when describing the differences between the beliefs of the scriptural geologists (Christian scientists) and the new theorists. For the most noted ones, he gave a brief description

Three indices were used for the analysis of abundance and diversity of the collected periphyton. The Shannon’s diversity index (H) (Shannon & Wiener, 1949) is a diversity index that is used to characterize species or genera diversity and account for their abundance and even the evenness. A high value of H would represent a diverse and equally distributed community and lower values would represent the opposite. A value of 0 would represent a community with just one species. Based on the periphyton

Developed in the 1950’s through to the 1970’s, plate tectonics is the scientific theory first proposed and elaborated by scientist, Alfred Wegener in 1912. The theory explains that the lithosphere is divided up into multiple plates that are moving constantly. (Cloos, 2018). This theory is regularly being adapted and developed as it has been through the past 400 years by several scientists. At first scientists, including Wegener only compiled a small amount of evidence supporting this theory. However

Genetically modified foods might cause illness such as cancer, according to Dr. Stanley Ewen, raised the concern that food and water contaminated with genetically engineered material could increase the growth of malignant tumors upon contact with humans. One of the disadvantages of using GMOs is adverse effects on the immune system. A study in 2008 showed that feeding mice engineered food for 30 days caused an immune reaction and altered the number of cells that regulated the immune functions in

a. Define biodiversity b. Explain how species diversity arises Explain how species diversity arises c. Explain the patterns of biodiversity on Earth d. List several regions of high biodiversity e. Define evolution. This week we are doing an assignment on teach back and I have chosen Biodiversity. I have found some great information on biodiversity but before I can go any further I need to understand what biodiversity is. What is biodiversity? Biodiversity means the diversity

Unit 12 Critical Thinking Assignment While Darwin brought us the theory of evolution, William Hamilton contributed with significant views on such evolution through a genetic standpoint. More specifically, after lengthy research and important demonstrations Hamilton became one of the most important evolutionary theorists of the twentieth century through his concepts of kin selection and altruist behavior in nature. As he realized that the simplicity of natural selection could only be seen in an
