The system stays irrelevant from the end result of following the principles for the justification that the duty has to be performed by any means. When any theory is presented criticism comes along and has a few important features also. The basic feature of this system is following the duty in any circumstances but the harmful fact of the duty has to be over looked. The consequences have to be chosen over the least possible one and the duty which is less harmful after the duty is enacted.
The use of utilitarian system simply distinct form the above mentioned one in a simple manner where the consequences are known and cannot be chosen and a series of data should be available. The rules of this system make it available for short term use where no importance is given to length examinations. It poses environmental problems and causes an impact to human life due to different way of approach towards life. The draw back of this system is that it fails to define prohibitions and find the importance of species. Both the species of humans are put into account and considered similar in any context but when put under large consideration animals are compared to humans and their well being also. Considering everyone the same and all given the same importance the species which need more attention come under scrutiny where they are similar to other species which do not need much of importance which makes this rule another draw back of this system
2. Explain three major differences between mitosis and meiosis. How does each difference contribute to the outcome of the process
2. Every living cell is composed of genetic material called DNA which carries chromosomal structure of an individual. The changes that take place in an individual and growth of the tissues are attributed to the changes that DNA undergoes during mitosis and meiosis. The main differentiating features among the two are as follows:
Mitosis can be generally defined as formation of two daughter cells from one; it can be simply explained as differentiation of the genetic material into two cells. The example that can be given to explain mitosis is the growth of tissues in skin, multiplication of blood cells.
Meiosis on the other hand can be differentiated from its meaning; reduction in the number of chromosomes into half and also involves the changes in DNA structure. The example that can be given here is the formation of foetus that is the end result of the above mentioned process.
The other main differentiating feature that can be mentioned here is after the process of mitosis the number of cells that are formed are two in number and have genetically same features and chromosomes as that of the mother cell whereas after Meiosis the number of cells that are formed are four in number and have different set of chromosomes and their genetic structure varies.
Mitosis is the process which generally occurs in somatic cells whereas Meiosis is the process ...Download file to see next pagesRead More

...? Effect of Marijuana on Sleep Patterns of Young Adults EFFECT OF MARIJUANA ON SLEEP PATTERNS OF YOUNG ADULTS Potential therapeutic effects of marijuana include pain relief and sleep quality alterations. This has been attributed to the hypnotic effects of the drug. This study investigates the effect of marijuana on sleep patterns. Current studies have been conducted using doses that are, in use, to relieve pain. Cannabinoids in marijuana are understood to be the principal psychoactive constituents of marijuana through cannabinoid receptors in the brain (Shapiro, 2011). While the cannabinoid constituent may be free of central brain activity, it may possess potential therapeutic characteristics due to its anti-convulsant and myo... Effect of...

... Biology Questions Give a specific example of how natural selection drives evolution Through the process of natural selection as explained by Charles Darwin, all organisms’ exhibit variations which are genetically inherited. Those variations that are better suited to survive in a particular environment are selected by nature through the process of natural selection. These organisms in turn produce offspring’s with similar traits and better adaptation to survive. This contributes to the process of evolution. A fine example of natural selection is provided by the finches that were observed by Darwin during his expedition to the Galapagos’ islands. He found 13 species of finches and each species exhibited variation is beak size and shape...

Molecules are made up of two or more atoms, either of the same element or of two or more different elements, joined by one or more covalent chemical bonds. Cell1 In biology, it is the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. Cells can be separated into two major groups—prokaryotes, cells whose DNA is not segregated within a well-defined nucleus surrounded by a membranous nuclear envelope, and eukaryotes, those with a membrane-enveloped nucleus. Within cells there is an intricate...

...Preserving the diversity of life Why should biodiversity – the diversity of life - matter to us? Why should we worry about preserving it or worry about evolution and heredity? Fossil records show that species have always gone extinct naturally over periods of millions of years. The pace of extinction in this era has gone up and concerns are raised over various causes. While man’s impact on the environment is causing species to vanish at a rate much faster than the normal rate, a large meteor could affect the earth and life in many ways. Different scientists have given various predictions if a large meteor were to affect the earth. A large meteorite could weigh several tons and hit the ground at a speed of some 40,000 kilometers...

Running Head: PNEUMONIA Pneumonia An Essay About a Disorder Affecting the Human Respiratory System (Your School or Organization) Pneumonia
The respiratory system is a series of organs designed to facilitate the exchange of gases, primarily oxygen and carbon dioxide, between red blood cells in the circulatory system and the outside environment (Thomson Gale, 2006). Pneumonia is one of the common diseases affecting the respiratory system. Pneumonia is an infection of the alveoli. Tissue fluids accumulate in the alveoli reducing the surface area exposed to air. If enough alveoli are affected, the patient may need supplemental oxygen (Kimball, 2007). Below is an illustration of how pneumonia affects the respiratory system.

Relationship among Religion, Biology, and Science

...Relationship among Religion, Biology, and Science Introduction The burning question is if there will be any connecting bridge to link religion, biology and science. Biology is a branch within the science sector hence it will be covered as science. The recent ideological clashes in the United Sates on the debate about creationism versus evolution have led to the perception that science and religion has a wide gap between the two that seems unbridgeable (Brandt-Rauf, 2006). This is an indication supporting the fact that science and religion will never co-exist. Therefore, we are going to cover the relationship between science and religion and see how the two perceive the other. The paper is is going to handle three main religions common...

... Biology Barbara McClintock McClintock was a research scientist who studied how chromosomes in maize changed and how they underwent transformation during their reproduction stages (Spangenburg & Moser 35-41). Through her laboratory research, she was able to develop a groundbreaking method of observing maize chromosomes as they developed. Spangenburg & Moser write that she used microscopic inquiry to explain different genetic developments (35-41). By narrating the process of genetic recombination during meiosis, she developed a maize genetic map. Finally, she elaborated on the role of centromere and telomere the central part of genetic transformation in maize (Spangenburg & Moser 38). Using the developed theories, she was able to explain...
