History of biology

psychologists and sociologist claim environmental factors are responsible. Keep in mind, three factors are responsible for gender development that includes biology, natural selection, and the environment. While each of these approaches has made their contribution to gender development, caution should be practiced…

Evolution, as defined in (what is evolution), is change in the characteristics of living organisms over generations. Natural selection is used as a mechanism for evolution; organisms that are “picked” by natural selection evolve and pass on their genes. Drastic changes in environment, such as the nuclear apocalypse in The Day After, or the frigid blizzard-hurricanes in The Day After Tomorrow, can alter natural selection and by relation evolution. All catastrophes- natural or manmade- have a…

fruit fly (drosophila melanogaster) to the offspring and we are able to do the test precision of the 3:1(monohybrid) and 9:3:3:1(Dihybrid) ratios. The model of fruit fly (drosophila melanogaster) is a really great model to work with in the field of biology more precisely (genetics) because it an organism that has been used many times to show scientific principles. We use fruit fly (drosophila melanogaster) as our model in this experiment because they are easy to get (cheap). They are small in…

Although people develop and change until the day they die, a vast amount of human development happens throughout the first few years of life, particularly infancy. An inseparable combination of both nature and nurture shape the baby and affect the infant throughout their whole life. In nature we see that the parent’s genes control what the child will look like and whether they will have any inherited, genetic diseases or dispositions. Additionally, habits during pregnancy, such as smoking or…

In Sigrid’s article, “Why should donating an organ cost so much?” he makes the argument that the Transplant Act set is doing more harm than good. The finical complications in organ donation is an important issue today because there are so many lives affected. The process of donating organs affects not only the patient’s lives, but those lives of the family and friends. Lingering thoughts of worst case scenarios and rejection are just half of the turmoil that the patients, friends, and families…

Evolution is a theory while it also is a fact. Facts are the data while theories explain those facts. Just because something is a fact does not mean it has a complete certainty, it just has enough data and evidence to verify a phenomenon. Darwin continually emphasized the difference between the fact of evolution and the theory of natural selection. In the 19th century when Darwin published his book On the Origin of Species the theory of natural selection became quickly accepted, besides a few…

1. Darwin understood that variations in the finch species pointed towards the idea that variation is the origin of evolution. Peter Boag continued to work tentatively alongside the Grants by extracting blood samples and DNA from the finches in his lab, then giving the Grants the data he would find. Boag and Hans Gelter have been running these various DNA tests on the finches provided by the Grants and hope to find the finch that created the different variations of finches along the Galapagos…

Scientists have shown that there is a development in polyploidy, which means that you have more than two sets of chromosomes. As polyploidy is somewhat confusing, there is two articles of explanation on this subject. I want to start by explaining gene doubling in an easier sense due to its confusion. Polyploidy can occur when organisms self-fertilize or through sexual reproduction. Through research, it's said that this process can possibly create a new species after being done. Although,…

Biology plays quite a lot on personality, people can be more likely to develop certain personality traits because they inherited them genetically. That is what biological psychologist’s study’s. There is an entire field of science called epigenetics that is all about how changes in behavior due to experience can affect people on a biological level and cause changes in genetics across generations. It’s far from the only thing that influences personality but it plays the part. Heredity plays a…

The experiences in the Biology 230 course will certainly continue to influence me in my understand of and how I approach topics in following biology and science courses. The reason why I say this is that the process that information is taught in the lecture course was a bit different from how some other courses would normally be taught. Comparing this course to previously biology and chemistry courses, this course focuses on the why rather than what is the answer. This certainly helps as it…
