Introduction:
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.
Method:
First we placed the slide under the simple microscope and observed it at ten times magnification level. We each took turns looking. We then copied them as drawings into our Cornell notebooks. After that we changed the magnification to fifty times and observed the slide. We each took turns looking. We then copied what we saw into our Cornell notebooks. After that we changed the magnification level to sixty times and we each took turns looking at the slide. We then copied what we saw into our Cornell notebooks and sat down together. When we were all done drawing we spoke about what we seen and gave each other ideas on how to write our Lab Reports.
Conclusion:
In conclusion I have noticed that without cells we wouldn’t be able to function or neither without cell theory because we would not know how to treat our body or our cells.
The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test and the indole test. The results for each of the tests performed are listed in Table 1.1 below.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
There were some moral problems that Mill ran into with his principle. One of the first problems was that actions are right to promote happiness, but wrong as they sometimes tend to produce unhappiness. By moving a victim from a mangled car would be the noble thing to do but what if pulling him from the wreck meant killing him. He intended to produce a happy outcome, but in the end he created an unhappy situation. Utilitarianism declares that men can live just as well without happiness. Mill says yes, but men do not conduct their lives, always seeking happiness. Happiness does not always mean total bliss.
First, Mill establishes the foundation of his theory by addressing how we should seek happiness in our lives. He says, “The happiness which forms the utilitarian standard of what is right in conduct is not the agent’s
In the book, Some Puzzles About the Evil of Death, it states that, “According to the most popular anti-Epicurean view, death is bad for a person primarily because it deprives him of certain goods, the goods he would have enjoyed if he had not died (Feldman).” This is known as the deprivation approach. In this situation, Doe would be deprived of good things such as marriage, having kids, meeting his grandkids, and etc. This is bad for Doe because he won’t be able to experience this when he ceases to exist. Also, the deprivation approach is important because it changes our perspective. If we know that death is bad, then we want to have as much of these goods as possible. Taking away Doe’s goods is like imprisoning an innocent man it is morally wrong. I believe that the deprivation approach is important because it sides with Feldman’s argument. It is a key reason why we should fear death and be aware of what we will be missing out on. We should cherish every second of our lives if we know that we are deprived of these
My leadership can expect a top tier performer who strives to be one of the most competent Non-commissioned Officer’s within the unit. I will do this by adhering to the regulations, unit sop’s and any other guidance which governs my section. I will ensure my soldiers do the same, holding them to strict but attainable standards and expecting nothing less. I will teach, coach, counsel, and mentor these soldiers-teaching them what a leader is and grooming them to be leaders also.
The Big Five Personality Test provided an interesting account of my personality. Although the majority of the results were accurate, I was surprised by two of the outcomes. According to this test, I am a closed-minded, unmethodical, social butterfly that is well-mannered towards others and composed under pressure (John, 2009). First, the results were completely accurate as I am extremely extroverted. I never meet a stranger, and I carry on conversations with anyone. From the custodian, to the cashier, to a random person on the street, it gives me a great sense of fulfillment to engage in dialogue with others from all walks of life. Second, I agree that I am polite and supportive, especially with family and friends. Overall, I try to always
...n was yet another display of the most beneficial style of leadership. Putting together teams, holding regular meetings in locations that were conducive to deep thinking, allowing debates, and discussions to take place, not choosing sides and arriving at a consensus is the very core of team building and fostering inclusive environments. Doing it all while displaying sound ethical principles routed in being a southern Baptist Minister enabled Dr. King to achieve huge successes as the primary leader of the Civil Rights Movement. Taking notes from one of the great leaders of yesteryear can and does help senior non-commissioned officers get better. Being an effective motivating speaker, putting the organization before self, team building, and having appropriate ethical principles to back it all up go hand in hand with leading Airman in today’s United States Air Force.
In John Stuart Mill’s “Utilitarianism”, Mill generates his thoughts on what Utilitarianism is in chapter 2 of his work. Mill first starts off this chapter by saying that many people misunderstand utilitarianism by interpreting utility as in opposition to pleasure. When in reality, utility is defined
MIll presents a form of hedonism that is quite contrary to its usual connotation. His "utilitarianism" is a principle stating that every person desires more happiness than pain and that actions are moral if they are condusive to this desire. Utilitarianism is empircally based, or centered around observation. Rather than seeking pleasure in any form, Mill contends that some pleasures are greater than others. He believes that, as humans, we are capable of intellectual pleasures rather than simple animal pleasures, and that these intellectual pleasure provide much more quality, which is far superior to quanity. Thus need a way to discern between which is more worthwhile. According to Mill, the only reasonable way to do this is to look at the
My Legacy Leader is LTC Brian A. Coppersmith, USA, Ret. LTC Coppersmith exemplified Army leadership from his character, presence, and intellect to his ability to lead, develop and achieve. LTC Coppersmith’s leadership ability directly affected me as a Human Intelligence Collection Sergeant operating under his command in garrison pre-deployment, and while deployed forward to Iraq. The example that LTC Coppersmith set for me is the foundation that I have used to guide each of my actions on as a leader. It is my hope that I will be able to positively influence and inspire at least one Soldier in the same manner that LTC Coppersmith inspired and influenced me.
LAB REPORT 1st Experiment done in class Introduction: Agarose gel electrophoresis separates molecules by their size, shape, and charge. Biomolecules such as DNA, RNA and proteins, are some examples. Buffered samples such as glycerol and glucose are loaded into a gel. An electrical current is placed across the gel.
In What Utilitarianism Is by Mill, we can see that society is very ambivalent about utilitarianism as a moral compass. “Utilitarianism is an ethical philosophy in which the happiness of the greatest number of people in the society os considered the greatest good.” In this theory anything that ends in happiness is considered as good and wring if it concludes in unhappiness. There is no moral ground rules when it comes to this ethical philosophy because overall happiness is the aim and not the actions that are taken to get there. Mill spends this chapter responding to the common criticism utilitarianism is faced with. Mill suggests that pleasure or happiness is the only criterion for deciding what is good and bad. He simply says that defines
Mill extended the theory in his book Utilitarianism, and was particularly well-known for his “hierarchy of pleasures in Utilitarianism” that he pointed out of
The value of different pleasures is also a point of interest for Mill. Mill’s version of utilitarianism requires a comparison between different types of pleasures. Mill says that pleasure can be measured by both quality and quantity. A pleasure could be consi...
