History of biology

birds remained. As with any small wild population, the Puerto Rican Parrot was bound to be affected by intrinsic factors. For example, a smaller parrot population increases the possibility of inbreeding depression. Genetic issues based on the life history of the parrot could also contribute. The bird mates for life and the average clutch size is between 2 to 4 eggs but the pairs don’t always successfully mate every breeding season. If a parrot loses its mate it may never try to find a new one…

Founder effect occurs if a small group moves from home to new settlements, this new family will have dissimilar allele frequencies from the original population it may be by chance either lack come alleles or have high frequency of others while population bottlenecks occurs when a large decrease in the size of an original population can eliminate a large amount of genes. 23. How does mutation increase genetic variation in a way that crossing over and independent assortment do not? This because…

pursue a degree in the Master of Occupational Therapy. Occupational Therapy school requires a lot of biology courses, which explains why I chose Biological Sciences as my major primarily. General Science was a better fit because it offers the option of having 30 hours of one science, and it introduced me to a variety of other science courses. In my case, my 30 hours of one science consisted of biology courses. Furthermore,…

The focus of this investigation is to record, process and interpret the zonation of a community of species on the rocky shore of Te Raekaihou Point. The site data was collected from the rocky shore at Te Raekaihou Point, and my chosen species are the Blue-Banded-Periwinkle (Austrolittorina antipodum), and the Brown-Barnacles (Chamaesipho brunnea). The community pattern found in the rocky shore is zonation. Zonation is the division of plants and animals into distinct horizontal bands, or ‘zones’…

Describe how you would perform a random sampling to estimate the size of the population of your species you chose in the Galapagos. Use some actual numbers in your description. Try to base it on real numbers (this may take some research). What underlying assumptions must be made for this technique to be effective? [ /6 marks] Random sampling is a method used by biologists to estimate the size of a population by collecting data as each organism usually can’t be accounted for separately. By using…

Introduction: History of the life on Earth shows species gain new traits as they evolve. Evolution is a development over time in response to the environment. Evolution is a scientific theory. Some evidence scientists have in order to prove this theory are fossils, homology, analogy, vestigial structures and embryology. The purpose of measuring these skulls is to show how our ancestors have evolved over the years. . Hypothesis: If the skull has similar measurements as the homosapien, then the…

started with scientific attempts to create genetically perfect plants. This then converted into laws that prohibited the marriage and mating of individuals of different social statuses (Black, 2003). One of the most productive scholars in the history of…

The LGBT (lesbian, gay, bisexual, transgender) community is always being discussed whether it be because, people do not agree with the life style or simply because they are trying to discover why someone is homosexual. The largest part of this discussion is if it is a genetic doing or if it is the environment in which someone is raised in. Some communities of people believe that it can actually be a combination of both that is the ultimate determination of someone being homosexual. Nature versus…

A dog, cat, and any other mammal you see today have a common ancestor with you and other humans. Scientists believe that evolution took place and can be proven through the homologous structures of prehistoric/modern whales and other mammals and DNA comparisons between species of mammals. The advancement of the whale species and their bone structures is an example of how evolution takes place in mammals. From the film “Morphed: When Whales Had Legs,” I took notes of how prehistoric whale species…

The Spillway or City Park: Which has more arthropod diversity? Author: Madeline Lafargue BIOS1071-007 Group Members: Rebecca Ostrowski and Khayla Wright ABSTRACT The purpose of this study is to find out how habitat type affects arthropod diversity. There are many different types of arthropods, making up the majority of animal life on Earth. Arthropods vary among different climates and conditions, including some near water habitats and some habitats without water. The following…
