Bacteria are unique organisms that have this material inside their cell walls and no any other organism has this material. Some of the eukaryotic cells have cell walls for example eukaryotic animal cells do not have cell walls while eukaryotic plant cells as well as fungi have cell walls that consist of cellulose and chitin (Black 93). Prokaryotic cells lack a nucleus but there is a central nuclear region. In addition, prokaryotes also have a single molecule of DNA that is circular in shape. Nucleus is the most important and unique part of eukaryotic cells and maximum DNA of the cell is present in the nucleus and multiple molecules are present (Campbell and Farrell 16). In prokaryotes, DNA is located in the nuclear region that does not have any membrane while in eukaryotes DNA is enclosed in Nucleus covered by nuclear envelope (Black 80). Eukaryotic organisms are bigger in size as compared to prokaryotic organisms for example eukaryotic organisms consist of size from1 micrometer to 1 millimeter while prokaryotic organism consists of size from 1 to 10 micrometers. Eukaryotic animals have centrioles and centrosome while eukaryotic plants, fungi, algae and prokaryotic organisms do not have centrioles and centrosome. ...
example, all eukaryotic cells have mitochondria except oddball parasites and all eukaryotic plants have chloroplasts that help in the food making process with the help of photosynthesis (Campbell and Farrell 19). Binary fission is the cell division process in prokaryotes while in eukaryotes, cells divide through mitosis and meiosis. Prokaryotic cells divide by asexual reproduction but eukaryotes divide by asexual as well as sexual reproduction (Black 80). Prokaryotes as well as eukaryotes can be autotrophic (generating food themselves) as well as heterotrophic (getting food from other sources). Examples of prokaryotes are bacteria while plants and animals can be taken as examples of eukaryotes. Autotrophic prokaryotes are photosynthetic (who make organic food using energy from sunlight) as well as chemosynthetic (who make organic food using energy from inorganic chemicals) while eukaryotes are photosynthetic but not chemosynthetic (Black 81). Difference between Endocrine and Exocrine Glands Human body consists of two types of glands that are endocrine and exocrine. Endocrine system contains glands that are responsible for discharging their secretions. Endocrine glands are responsible for discharging their secretions within the body while exocrine glands secrete on the body surface. The secretions that are secreted by the glands are the hormones (Clark 229). There are number of hormones that move from here to there in the body in the flow of blood. Level of hormones is influenced due to minerals in the blood, stress, infection in the body and misbalance in the fluid. Both exocrine glands and endocrine glands are formed from epithelial tissue (Clark 229). Exocrine glands secrete with the support of ducts while in endocrine glands, no distinct ducts are present for ...Download file to see next pagesRead More

The Difference between Sickle-Cell Anemia and Malaria Resistance

It has been found that this disease is very well equipped in resisting malaria or in other words sickle cell anemia is a fairly effective resistant against malaria. The carrier of this always carry an amount of this disease in their blood cell as this genetic disease is very recessive in nature. For this reason this complementing disease is referred to as heterozygote advantage.

This phenomenon happens because as a rule the malaria parasite needs to be embedded in blood cells to reproduce but the blood cell of an infected person resists the parasite plasmodium to settle down. Thereby depriving the parasite to reside and multiply. In this process, the sickle cell disease prevents the carrier from probable infection of ma...

Respiratory, Endocrine, and Cardiovascular Systems

The person is a smoker all his life. The person has shortness of breath and a reduced ability to work. All the parameters measured with a spirometer indicate reduced pulmonary function, and expiratory flow rates are also significantly decreased. This limitation in airflow is a hallmark of emphysema. Emphysema combined with shortness of breath and reduced ability to work indicates hypoxia which might have been caused by perhaps small airway disease and associated chronic bronchitis. Everything taken together, this person is suffering from the chronic obstructive pulmonary disease (Phillipson and Slutsky, 2000, 2139-2152).

In this disease, there is emphysema that occurs due to the destruction and enlargement of the lung...

What Are the Ethical Postives and Negatives of Stem Cell Research

...Bioethical issues have taken on a fundamental importance in our society during the past century. As science and technology have collectively pushed the boundaries of what is possible, or what is conceivable, ethics should never be left out of the picture. Although, to quote Immanuel Kant’s famous formulation, an ought implies a can, a can does not imply an ought. In other words, simply because humans have the capability of performing some deed, as novel or interesting as it is, we must first question whether it is the right thing to do. A particularly contentious issue in bioethics is that of stem cells, which is largely opposed by individuals who see the world normatively in one state of mind. Meanwhile, others may see the same issue...

Research paper on Stem Cell Research Legislation and the related legal issues:

...The isolation of human embryonic stem cells by Dr. James A. Thomson and its potential use in treating various diseases marked the beginning of the widely debated issue about stem cell research. Stem cells are totipotent in nature by which they have the ability to differentiate into any kind of human body cell such as blood cells to skin cells. Scientists are making strides to capitalize on this inherent nature of the stem cells to repair damaged tissues (AAAS Policy Research, 2010). However, despite the immense utility of stem cells, it is also been associated with several moral and ethical issues which has resulted in several country specific legislations and legal regulations both in the United States and several other countries...

Stem Cell Research Policies Around the World

...Stem Cells Institute’s Introduction Stem cell research has been one of the most prominent developments by mankind and its discovery has been credited to two scientists, James Till and Ernest McCulloch. They also defined the two key properties of stem cells namely self—renewal and their ability to differentiate into several kinds of cells (James Till 1931, n.d). Their discovery has now led to the development of promising cure for a wide range of diseases ranging from diabetes to Parkinson’s disease. There are many sources of stem cells used in research and these include embryonic, fetal and adult stem cells. Among these, the use of embryonic stem cells has been the most debated and opposed as scientists maintain that of the many potential...
