The simple MFC will be made from plastic containers, PVC pipes, agar or Gore-Tex membranes, and galvanized metal mesh for cathodes. The experiment will include comparing the efficiencies defined by the amount of energy per dollar spent in the construction and installation process of the traditional MFC, as provided by the college laboratory and the MFC built from common and less expensive substitutes.

Monohybrid inheritance entails a cross between two parents possessing different forms of a gene (alleles) referred to as monohybrid inheritance. Parental characteristics passed in this manner are primarily determined by genes

n it, it provides detailed information on how Cochran found it hard to understand why the natural selection principle by Darwin did not take part in eliminating the dangerous genes from a Jew’s gene pool. However, it also expounds on how Cochran justified the occurrence of the

The primary function of the brain is to regulate all the activities of the human body. It is composed of three regions namely the cerebellum, cerebrum, and the advanced marrow (Mader, 2006). The cerebrum serves in conscious actions such as speech, movement, sight, and memory. The cerebellum performs the role of body balance regulation and muscle coordination for movement.

Enzymes play a significant part in altering the reaction rate in all biological reactions, where they are present. Mostly, enzymes are in the form of proteins in nature. By altering the reaction rate, it means that they either slow or make fast the rate of reaction. Proteins fundamentally act as enzymes that enhance the rate of reaction inside the cells.

They sense the presence of small lipophilic molecules like steroids and various other hormones and regulate the expression of the genes concerned with these molecules, thus assisting in various functions the molecules are destined to perform (Novac and Heinzel, 2004). Thus nuclear receptors act as ligand-inducible transcription factors.

The digestive system is affected by cystic fibrosis in several ways: firstly, the sticky and thick mucus interferes with the normal functioning of the pancreas by blocking its ducts, thereby preventing insulin and other digestive enzymes from reaching the intestines and aiding digestion, thus fats, proteins, and vitamins are absorbed.

This manifests as autoimmune disease. On the other hand, if incorrect communication makes the immune cell perceive a sick cell to be

According to Rogers, fallopian tubes function as conveyor tubes connecting the ovaries and the uterus. They have correct balances of ph and fluid as well as a supply of Celia to convey the ovum safely to the uterus. They are important in the reproductive system in that they act as fertilization sites before the zygote could implant in the uterus.

Protein supplements are, therefore, necessary only for underweight people and lactating females because there are some non-essential amino acids that the body needs, but does not biosynthesize (Protein, (n.d.). An individual on dialysis needs supplements because the body loses so many proteins during dialysis.

A higher frequency of vibration means there is a high pitch while a lower frequency of vibration means there is a lower pitch. There is a range of sound that is heard most accurately by the human ear. Such sounds are from sources that vibrate at frequencies

The reason for performing this combinative experiment was also to show how angiogenesis could be inhibited as a major cancer chemotherapy strategy. To realize this, the researchers largely combined the two drugs, captopril, and artesunate in the establishment of quail embryos chorioallantoic membrane assays.

The cells making up the taste buds have different chemical receptors for the different types of dissolved chemicals being introduced to the tongue. For example, when tasting something salty, specific salt

This was the stage where the disease was discovered and thus the coinage of the term ‘lupus’. The subsequent stage that followed was the neo-classical era which was mostly concerned with the general symptoms of Lupus, and lastly, the contemporary era which marked a shift in the medical research in this area when in 1948 the LE Cell was discovered.

Different proteins perform different functions in our bodies. Some proteins just form the structural units of our body e.g. Muscles whereas other such as Albumin acts as a major protein to maintain an osmotic gradient between the extracellular matrix and blood vessels n order to avoid edematous conditions. 

Due to their high demand, drugs are scarce leading to sky rocketing of prices thus raising questions concerning the cost of producing drugs. Production of newly discovered drugs is expensive and requires huge sums of money during packaging and marketing. During

Although most cases of tuberculosis infection worldwide manifest primarily as lung disease, one-third of the cases actually affect other organs (Fauci et al, 2008). M. tuberculosis

Chronic leukemia has varied biology and natural history, and may develop into antagonistic and difficult-to-treat stages. In its first stages of development, persons with this disease may experience few or no symptoms. However, most

 Each cell has a nucleus. Within this nucleus, the DNA of the organism exists in it, as chromosomes. The numbers of different chromosomes change depending on the type of organism. However, the structure of these chromosomes does not change. A chromosome is made of two identical strands, called chromatids. These sister chromatids lay alongside each other and are joined. 

The report indicates that most of the gram-negative bacteria show a lot of resistance to antibiotic drugs. Germ falls in a category of bacteria, which has killed millions of people in the world. Gram-negative has effects on the bacteria due to its nature of staining. We can easily distinguish between gram-positive and gram-negative staining.

According to the experiment findings it was evident that the east coast had the majority. The main reason for this is that, this is the site where the European green crab; a snail predator, reached after migrating from Europe in the early 19th century. To carry out the experiment the researcher used four tanks that were filled with water, with one additional tank that would act as the control set.

The most recommended test for tuberculosis is the tuberculin skin test also known as Mantoux tuberculin skin test owing to the fact that it has very little side effect in the life of the patient. The tuberculin is a form of

Formaldehyde is in its gaseous form at room temperature; it is monochrome and has a strong, annoying smell. It is an essential component of many chemical compounds such as polymers. Formalin is the saleable form of formaldehyde found in water. It was previously used for conservation of biological specimens and disinfectants.

The article reviews the expression of luciferase or green fluorescent protein from the promoter of the clock period in order to monitor the circadian clock in explanted abdominal tissues, head, and thorax in transgenic drosophila. The observed photoreceptive properties of the explanted tissues indicate the role of unidentified photoreceptors in photic signal transduction of the clock.

She was made known to the world in 1997. This is a picture of a cloned pig in Denmark in 2009. Cloned animals are normally produced using SCNT or somatic cell nuclear transfer. The process needs a somatic cell, which

The U.S. Surgeon General has defined attention-deficit hyperactivity disorder (ADHD) as “ a metabolic form of encephalopathy, impairing release and homeostasis of neurological chemicals, and reducing the function of the limbic system.Research has indicated that in all likelihood it is the frontal lobes, their connections to the basal ganglia and the central aspects of the cerebellum that are involved in ADHD. 

mechanisms and requires sufficient transportation to body cells while carbon dioxide, a metabolic waste product, needs elimination from cells’ environments. The two processes occur in the gaseous exchange process that I explain in this paper, the process by which

It is a microorganism that causes a disease. This microorganism usually has specific features which render it harmful to its host and gives it the ability to cause disease. These features result in different classifications of pathogens. Hence, there are several examples of pathogens that include fungi, viruses, bacteria, and protozoa.

Most people smoke e-cigarettes only in public to cut the number of usual cigarettes they smoke during the day; however, they smoke usual cigarettes at home. Such a behavior is still a promotion of secondhand smoking which is harmful for all people. Children and
