Evolution and Antibiotic Resistance | 11/5/18-11/9/18


Summary:

       Antibiotic resistance is when a consumer consumes the antibiotic drugs more than prescripted. This allows bacteria to grow resistant to the antibiotic drug faster than at a regular pace. When the bacteria gains resistant to the antibiotic the only resort is to use a stronger (and more expensive) antibiotic biotic. Bacteria’s resistance towards antibiotics are absurd. Being able to go through versions of antibiotics multiplied, once, ten times, one hundred times, and even one thousand times in less than 11 days. The bacteria evolves and gains resistance of the antibiotics so fast it becomes terrifying. This means that humans can be in severe danger as bacteria are becoming incredibly resistant to antibiotics which is what most humans rely on to fight bacteria, viruses, and diseases. Natural selection influences the effectiveness of antibiotics and the virulence of infectious agents through the most fit bacteria (diseases, and/or viruses) that is resistant towards antibiotics reproducing and the bacteria that is not resistant dying off. This will cause only strong bacteria to be alive and thus making antibiotics almost pointless as they won’t do much to stop the evolved bacteria. So natural selection of bacteria, viruses, and diseases will eventually lead to almost all of these harmful things to be resistant towards antibiotics, drugs, and medicine. So, natural selection will essentially make antibiotics ineffective through evolving bacteria, diseases, and viruses to make them immune to antibiotics.

S&EP 6-Constructing Explanations and Designing Solutions:

The Evolution of Bacteria on a “Mega-Plate” Petri Dish by Rkishony
       I constructed an explanation of how natural selection influences the effectiveness of antibiotics and the virulence of infectious agents when researching to develop a public relations campaign to help inform the general public about the threat of antibiotic resistance. I constructed this explanation by following the ACE strategy where your explanation consists of an answer, cite, and extension/explanation. Through doing so, I created a very complete response to this question that can truly give a better understanding on the topic. It teaches you how natural selection effects antibiotics, where we got that information (how we know), and a further extension of how we know and where we got that information. Natural selection changes the effectiveness of antibiotics through the most fit bacteria (the bacteria that is resistant towards antibiotics) living long enough to pass on their superior traits/genes. This can be seen in a video created by Science News titled, "Watch Antibiotic Resistance Evolve." In this video bacteria go through versions of antibiotics multiplied, once, ten times, one hundred times, and even one thousand times in less than 11 days. This allows us to understand that over time, the only bacteria that will be left are bacteria that are not affected by antibiotics. Thus causing antibiotics to be pointless, and over time, less and less effective.


XCC-Stability and Change:

       The system that I identified this week is the system between antibiotics and bacteria. The system is that as humans continue to use more antibiotics to fight bacteria. Bacteria evolves through a process known as natural selection and becomes more resistant towards the antibiotics that we are using. What would make this process more stable is taking prescribed vaccinations from doctors and cleaning up scratches, scrapes, cuts, wounds, etc. As well as critical or chronic conditions. Two other ways would be being able to recognize if a wound is infected; contact or get further help and clean the environment around you, anything and everything carries germs and bacteria. THe last way would be just to use antibiotics more responsibly and wisely (through using them less often and only when you really need them).

The Sulfur Cycle 1/20/18

Summary:        This week in science we learned about biogeochemical cycles, more specifically, I learned about the biogeochemical cycle known as the Sulfur Cycle. What I now know about the Sulfur Cycle because of what I learned this week through research is each part in the sulfur cycle. I also now know that their are a lot of different parts in the sulfur, but my focus was trying to make this complicated cycle very simple and easy to understand. The first part in the Sulfur Cycle is  Hydrogen Sulfide Gas is released into the atmosphere by the eruptions of volcanoes, hot springs (“ spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust. ”) , and the decay of living biological sulfur-containing materials in swamps, bogs, and tidal flats. Sulfur is also released from the ocean in sulfur-containing compounds in sea spray, and as the gas hydrogen sulfide. I also know that most of the sulfur released from the world's oceans does so

Plate Tectonics 3/10/18

Summary:        This week in science we learned about Plate Tectonics. Plates have been on Earth for thousands of years and are consistently moving (very slowly). Through this the Earth can recycle our land, by destroying the old land, and creating new land. These plates are made of rock and are in the lithosphere layer of the Earth. Another thing I know is that there are 3 different type of plate boundaries. Those three types of plate boundaries are convergent boundaries, divergent boundaries, and transform boundaries. Convergent boundaries are when two plates collide and their are two different types of convergent boundaries. The two types of convergent boundaries are collisional boundaries and subduction zones. A collisional boundary is when two plates with the same density collide. Because they are the same density the plates buckle and warp. The land then pushes up into jagged peaks forming a mountain. Subduction zones are when one dense ocean plate converges with a lighter con

Analog Vs. Digital debate - WAC 3 Argument | Nicolas Reed-8th Grade Science

nreed1005 Ms. Garcia Science 8 4/5/19 Digital is Better than Analog        “There's an ongoing flood of new LP releases (Amazon currently lists 938,000 LP titles ). Kings of Leon, Taylor Swift, Nine Inch Nails, and Kanye West all have their latest releases available on LP.” according to the article titled, “Why does analog sound better than digital,” by Steve Guttenberg. Digital is better than analog. Digital allows you to have a clearer sound that is controllable and can last forever. Most importantly, it is cheaper, which means that it can used by almost anyone. Analog is the past, we must invest in the future and use digital.        Using digital means having high quality sound that can be manipulated. “Digital has certain perfect things about it [, it] immediately solved all the problems of analog background noise, hiss, where pitch control all of those things.” according to the video titled, “Analog or Digital? (1993),” from PastVid. Digital allows you to have “go
