Biology science of duty - Essay Example

The most important feature of this system is the basic rule of adherence to the duty no matter what the consequences are following the duty. 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 system2.

Explain three major differences between mitosis and meiosis. How does each difference contribute to the outcome of the process2. 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
