Enzyme known as superoxide dismutase, eliminates superoxide radicals by enhancing the rate of reaction. During the process, toxic substance hydrogen peroxide (H2O2) and hydroxyl radical (OH-) are produced, which, in turn, is dissipated by catalase and peroxide enzymes respectively. The catalase test is used to identify such organisms.

The fluorochrome is bound to an antibody and this antibody bids to the cells. The light source usually used is a laser light. The cells are hydro-dynamically maneuvered such that only one cell intercepts the laser beam at a given time. When these cells intercept the laser beam, light is scattered by them and absorbed by the fluorochrome.
They are common aquatic organism because they have the capacity to adapt different aquatic environments ranging from freshwaters to acidic swamps, lakes, seas, rivers, wells and ponds. If one studies the effect of nicotine on Daphnia, the ultimate results are fatal (Fitzgerald 12).
When human beings take in foods such as vegetables and carbohydrates, they must be broken down to smaller particles that can be absorbed in the blood and body cells. The human digestive system is made up of a combination of organs from the mouth to the anus.
It requires that two or more coding sequence are combined, so that a new gene is formed, where the promoter gene is used to express in the newly gene component, while the reporter gene replaces the coding region, such that instead of the gene replication producing the original protein component, it is the reporter gene that will be expressed (Clark, n.p.).
Null hypothesis is that of no difference while objective hypothesis is that of difference (Mackey & Gass, 2005). In this case, the hypothesis in this study will be: There is a significant drop of sugar levels in blood of the mice treated with black coffee compared with those treated with water.
The author explains that the way living organisms adjusts their bodies to the impressions of stimulation by adjusting to such stimulant after some time. "Sensory adaptation" is decreased sensitiveness of the sensory receptors because of overstimulation. This process enables living bodies to perform a function in specific unpleasant situations.

There are natural threats to the environment such as earthquakes and tsunamis, and there are artificial threats such as poor water treatment, air pollution, and inappropriate dumping of toxic wastes. According to Kibert, the US Environmental Protection Agency (EPA), environmental justice is termed as the fair treatment of all people, regardless of race, ethnicity, and socio-economic status, among other discriminatory factors, in the implementation of environmental laws, policies, and regulations (170).
Growth Hormone is secreted in a pulsatile manner from the anterior pituitary gland. It is a peptide hormone consisting of 191 amino acid residues and contains 2disulphide bonds. Growth hormone secretion is regulated by hormones like GHRH , Somatostatins and Somatomedins which either stimulates GH or inhibits GH release by positive and negative feedback effects respectively.Conditions like hyprglycemia and prolonged sleep increases GH secretion levels.

The term "Dinosaur Fossils" is made up by combining two Greek words: Deinos, meaning "terrible" and Sauros, meaning "lizard;" with the Latin word Fossilis, meaning "dug up." This means that the term “dinosaur fossil” literally means the "great lizard dug up." It was first used by British anatomist Sir Richard Owen in 1841( Dinosaur Fossils - Age Old Debate, 2012) These creatures evolved into a very varied range of sizes and shapes, from the enormous slow moving, plant-eating sauropods, to the quicker tyrannosaurs, whose teeth show that they were meat eaters.
It includes members exhibiting variations in body forms, for example, some are unicellular while others are multicellular. Protists have chloroplasts and can manufacture food through the process of photosynthesis. All protists have mitochondria and can carry out respiration (breakdown of glucose to yield energy).

Second, there is the school of thought that describes drug abuse as a type of self-fulfilling prophecy with relation to the way people understand and categorize it. What one can see from this debate, prior to seeking to develop their own point of view with relation to the issue, is that one viewpoint attempts to explain drug use by way of a mental/spiritual deficiency in terms of lack of willpower.
The results of experiment 1 regarding the effects of potassium and calcium chlorides on antibiotic activity indicated that the zone of inhibition reduces with the increasing amounts of cations in the culture. Generally, Potassium chloride produces monovalent cations (K+) while Calcium chloride produces divalent cations (Ca2+ ).

Viruses are the tiniest of organisms and yet they have the power and strength to attack all other organisms including human, animals, plants, bacteria, etc. The viruses are almost hundred times smaller than a bacteria cell which themselves are quite tiny.
Osteoporosis is a skeletal disease that is characterized by reduced bone mass and loss of bone tissue leading to fragility, brittleness, and frequent fracture of the bones. This condition increases the risk of bone fractures, especially in regions of the body such as the spine, wrist, as well as hip. In most cases, osteoporosis begins to develop early in life but is often diagnosed in old people, especially women.
The molecular clock hypothesis also serves as a null model, which is usable in testing both the rates of mutation and evolution in various species. Molecular clocks continue to influence significantly the development of molecular evolution theories. The use of molecular clocks has also experienced a marked increase allowing for its profound effects.
37). Typhoid fever remains one of the most common health problems causing millions of illnesses and fatalities around the world. Salmonella enterica serovarTyphi share adaptation to human host with other serovars like Paratyphy A, Paratyphi B, Paratyphi C as well as Sendai (Porwollik, 2011).
Asepsis is achieved by ensuring that all people who come into contact with the patient scrub their hands and wear sterilized gowns with disposable masks and gloves. In addition, the operating room air and equipment must also be clean. Asepsis is targeted at eliminating the possibility of infection while anti-sepsis is the use of chemicals to destroy germs already in the body or wound.
Opium poppy has a complex history as it has brought great problems, as well as great benefits to the human society (Lee et al., 2011). This is, probably, among the earliest medicinal plants that human beings had discovered.

Emerging diseases are then categorized as newly emerging diseases, deliberately emerging and re-emerging diseases on the basis of their course or incidence and the occurrence according to time and place (L.Guerrant et al 2011). Recent researches and studies have brought into light many emerging infectious diseases which are both a serious threat to human health and require medical interventions and preventive measures.
Mutations in a gene can lead to non-functional enzymes, disruption of protein structure, or altered protein conformation affecting normal protein functioning. Such abnormalities often result in various genetic diseases. For instance, mutations in the gene, GALT, can lead to an inherited autosomal recessive disorder called Classic Galactosemia or Galactose-1-phosphate uridyl transferase deficiency.
It is imperative to classify bacteria and identify microorganisms as they have enough potential to cause various diseases. The identification process is highly pragmatic for the correct diagnosis and treatment. Identification of the bacteria provides a line of treatment. Bacterial identification is the foremost step to accomplishing further investigation procedures.
The author states that the target of monoclonal antibodies is specifically the different proteins that mostly cause cell activities. These proteins include the receptor cells and other proteins that are present on, the surface of both the cancer and the normal cells. The monoclonal antibodies are very specific.
The combination of an RDD and a conventional explosive essentially achieves the aim of dispersing radioactive material in the targeted location, the impact of which is dissimilar to that of a nuclear bomb (Medalia) however, the physical and biological effects of dirty bomb detonation are indubitable.
These are the main symptoms of asthma, and it means that a person who experiences them should seek medical check-up. The causes of asthma include air, animal fur, tobacco smoke, and chest infections. These causes introduce particles that irritate the bronchi in the lungs and cause them to swell and take in less oxygen.
A pap test is the common procedure through which testing on cervical cancer is done where an early detection of the cancer enables a successful treatment (Richardson et al, 2010, p. 1769). The HPV (human papillomavirus) is the common cause of cervical cancer though not all HPV causes it (Anon, 2013, para 3) .Nevertheless, smoking is equally associated with causing cervical cancer by CIN3lesions (Plummer et al, 2003, p.
