It is not correct to use the term "ancestral" to describe platypuses relative to mammals that bear live young because although they share a common ancestor platypuses diverged into a separate group before the mammals that bear live young evolved to acquire the trait. Platypuses can however be described as being "more primitive", because they have gone through far fewer evolutionary changes than the mammals that bear live young have. 

Ecology being a branch of biology that deals with relations between different organisms and their physical surroundings, I believe relates to healthcare. The way that organisms around us behave essentially affects the way that us(humans) live and vise versa. Our interactions on a day to day basis is not only affecting organisms, but it is affecting ourselves as well. Environmental conditions are a major factor in determining our lifestyle including; the amount of pollution which is eventually leading to global warming and affecting air circulation and atmospheric convection cells. Global warming soon then leads to extinction of animals which then will affect other organisms food chain/living habits. As global warming increases, peoples health conditions begin to decrease and that’s where healthcare comes in.

For this draft I wanted to do some observational writing. I am going to observe my calculator. On the back it scratched, scuffed, and discolored complete with my name and phone number that my mother required I put on it in high school. The battery pack has education.ti.com enscribed on it. One of the three screw holes is filled with dust to the point in which you can’t see the screw anymore. The worn out serial number still remains 1215082533 K-0414B. Flipped over the cover has a graph etched into the plastic with the title TEXAS INSTRUMENTS above it. Once opened a blank yellow green screen is coated with dirt and scratches. Purple, black, green, yellow, and gray buttons line the face of the calculator. All the buttons serve their own unique purpose, with the purpose changing based on the previous buttons pressed. This seemingly simple machine has such incredible capabilities. This machine has and will carry me through exams plugging hundreds of commands into it. I wonder how long this took to craft, to assemble, to even conceive the idea of a handheld computing device that can calculate math problems beyond my comprehension in the blink of an eye. It really is something that is incredibly intricate but yet so simple.

Throwing the nutrient cycle of soil out of balance will only begin to hurt us rather than benefit us in the future. One way in which ecology can play a role in helping with this issue of soil fertility would be water filtration and oxidation reduction. However, although ecology can play a role in protecting our world’s soil fertility, humans themselves play a more important role. Humans have the ability of reducing global pollution which can then help with weather change in respect to soil fertility. Humans also have the ability of changing the way in which they practice farming which has substantially affected soil fertility at most. Nutrients that are stored in soil are needed for everyday life as well as the soil organisms that help with the decomposition of these nutrients.

Model genetic organisms are used to perform studies for better understanding of how the body functions and for genetic analysis. More specifically, systems of the body, such as the nervous system and digestive system, are closely observed over time. Drugs are also most commonly tested on model genetic organisms to collect results before being tested and available for human use. Aspects of model genetic organisms include having a short generation time and producing numerous offspring. This allows for transfer of genes and characteristics to be observed faster and therefore more efficient for the researcher. In addition, using models that are well known are most convenient to use. For example, mice is a common model organism because their bodily systems resemble those of humans. Not only are they easy to be reared in laboratories but they are also inexpensive to purchase. Research performed on model genetic organism have greatly contributed to advancements in medical treatment and the understanding of the transfer of genes today.

Update on the Unknown Organism (Larva)

The larva was given a peel of clementine skin. The organsim reacts be exploring the peel and proceeds to crawl beneath the tender, white, inner portion of the skin and appears to be eating the peel. Later, the organism remains still, lying beneath the peel. When disturbed, the larva retreats and clings onto the white portion of the skin. Over the course of three days, the organism changes physically and behaviorally. Changes include darkening of the skin, the spots along the side of the organsim, as well as the legs.There is also a decrease in activity and lesser response to disturbances (such as shaking the container). On the third day with the peel introduced, the organism does not seem to be eating the skin, but simply remains still, rarely moving beneath the white side of the clementine peel.

By the third day, the organism does not seem to be eating the skin, but simply remains still beneath it.

A subject that most interests me would definitely have to be healthcare. The improvement of health through science, diagnosis, prevention and the treatment of disease is fascinating and will always be changing. Not only is healthcare always changing, but there are so many careers within this industry including; dentistry, nursing, medicine, pharmacy, psychology, etc. I personally want to get into medicine and hopefully attend med school. Healthcare has a variety of aspects including both the physical practice itself and its policies. Healthcare policies are vastly dependent on the country itself and the community influence within its people. The fact that healthcare is such a wide field and always developing will continue to keep me interested in the field.
