Resistance to antibiotics may be considered to be an evolving process which is driven by the selective pressure of excessive use of antibiotics. In the hospital, the ICU (intensive care unit) which are crowded with debilitated patients receiving broad-spectrum antibiotics, provides the perfect environment for the emergence of antibiotic resistance
Genetic test records may form the basis of decisions made by parities such as insurers and employers and this negatively affects the people with the “wrong gene” (Schoonmaker and Williams 30).
The groups working
Plasma membrane is present in both Eukaryotes and Prokaryotes. It is the layer that separates the cell from the external environment. Prokaryotes may have either one or two layers of plasma membrane for example E.coli has 2
Natural disasters differ from hazards in that the disasters refer to the occurrence of the events, while hazards are the negative effects presented by the natural disasters. Hurricanes, for example, are commonly occurring natural disasters. Some of the main
Rotavirus is shaped like a wheel, which is the reason behind naming it "Rota" (Offit, 2011). The current statistics put rotavirus at 80% causative of death in all diarrhea-related with rotavirus. At least 600,000 Children die every year secondary to diarrhea resulting from
The wetland is touted as one of the most productive environment since it provides conducive environment for human and animal survival. In Mexico, the marine wetlands are cradles of biological advancement and diversity. The wetlands are characterized by providing water
The zoo like many other animal parks was filled with plants adapted to semi-arid areas. The grass was not that green, an indication of the absence of rain for some months. In connection with the class assignment, my interest was mainly on the herbivores specifically
Therefore, the oxygen intake directly correlates with the length and frequency of the stride. At rest, the heartbeat of a horse is 30-40 beats per minute. These increases when the horse is at full speed to a
Microscopy is probably the most important of all the methods used in biology. The vast majority of living organisms are too small to be seen with the human eye, and cells (the building blocks of living organisms) can only be seen with the
Initially, when it was discovered that DNA is present in the chromosomes, and the entire chromosome is made up of genes that code for proteins. However, with subsequent findings, now it is established that less than 10% of human chromosomes is composed of genes. The rest
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
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
Nuclear receptors are very important for the functioning of various molecules in our body. They are basically proteins found in the interior aspects of the cell. They sense the presence of small lipophilic molecules like steroids and various other hormones and regulate the expression of the genes concerned to these molecules.
al species detected by 16 S rRNA included, Actinomyces, Corynebacterium, Rothia, Propionibacterium, Atopobium amongst other highlighted by the graph above. As for culture-dependent bacteria, staphylococcus forms the predominant group. It is however worth noting that majority of
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
alize this, the researchers largely combined the two drugs, captopril and artesunate in the establishment of a quail embryos chorioallantoic membrane assays. Subsequently, computer based evaluations for quantitative studies were established on vascularization processes in vivo
The art is highly developed around the world especially in the United States and in Japan made possible with the advent of new technologies that widened the portfolio of available animation techniques.
For children diagnosed early with the genetic disorder, it is imperative that they avoid going for too long without food and, had this child undergone genomic newborn screening, this would have been realized and his parents able to take precaution and save his
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
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 was marked a shift in the medical research in this area when in 1948 the
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
