Prior to the commencement of the experiment, several hypotheses were made in regards to the efficacy of different household antibacterial products on two species of bacteria. The first hypothesis predicted that the most afflicted species of bacteria would be Staphylococcus aureus; the second suggested that products A and C would be more effective at killing both species of bacteria than product B; whilst the third hypothesis proposed that product A would be most active against S.aureus. The…

Sonic hedgehog signalling function during nervous system development 13354626 Katie O’Byrne words including references Sonic hedgehog (Shh) is a glycoprotein that is secreted by and diffuses through the developing nervous system. It is a member of the hedgehog family of signaling molecules. The Sonic hedgehog signaling cascade is an integral trafficking system that influences the pattering and growth processes involved in the development of multicellular organisms. Shh is particularly important…

The difference between nature and nurture is that nature is the idea that behavior is effected by your chemical and gene make up while nurture is the idea that you are a blank slate and your behavior is distinguished by experiments. They both effect behavior is what was discovered. * Dualism is supported by cognitive psychologists such as George A. Miller and Sigmund Freud * Rene Descartes dealt with Monism vs. Dualism & Interactive Dualism * Monism is the belief that the mind…

extraction for each set, the other sets’ was resting and the enzymatic reactions might have started to take place that then destroys the DNA and makes it less intact together after ethanol is added . There are enzymes called DNases found in the cytoplasm and its function is to destroy other DNA’s from virus or sicknesses that infects it. The DNA is normally shielded from the enzyme by the nuclear membrane, but in this experiment, soap has dissolved…

Lipid Digestion: Absorption and Transport of Lipids Lipid digestion occurs primarily in the small intestine though a small amount of lipids are broken down in the stomach. Special enzymes called lipases breakdown triglycerides the most abundant lipids in the diet and phospholipids. Lingual lipase secreted by glands in the tongue and gastric lipase secreted by gastric chief cells hydrolyze a small amount of triglycerides into fatty acids and monoglycerides. As chyme enters the duodenum from the…

1.0 Introduction – What is diabetes Mellitus? Diabetes mellitus is a progressive disorder of chronic hyperglycaemia due to insulin deficiency or resistance and in some cases both which affects people of all ages. The chronic hyperglycaemia causes a range of macro- and microvascular complications. Macrovascular damage leads to increased prevalence of heart disease, stroke and peripheral vascular disease whereas microvascular complications can cause diabetic retinopathy, neuropathy and…

Transcription is a process which information from DNA is converted into its RNA equivalent which also refers to the synthesis of RNA copy of information encoded on DNA. The same principles of transcriptional regulation apply to both eukaryotes and prokaryotes. Transcription involves in access of transcription apparatus to DNA, recognition of promoter sequences, initiation of RNA synthesis, elongation of RNA, and termination. Transcriptional in eukaryotes is more complex compared to prokaryotes…

Type 1 diabetes mellitus is a chronic disease in which the body’s own immune system erroneously attacks the beta cells of the islets of Langerhans located in the pancreas that produce insulin, resulting in a high level of glucose in the blood. Insulin is needed to transport blood glucose (sugar) into cells. The sugar is then stored in the cells and used later for energy. “In these duties, insulin acts as a regulator of gene transcription” (Cox, 688). When beta cells produce too little or,…

The Extraordinary Science of Microbiology There are a wide variety of microorganisms in this world. The major groups of microorganisms include bacteria and fungi. These microorganisms are found all over the earth. The study of microorganisms started in the mid-1600’s. Most people believed that microorganisms only spread deadly diseases, but scientists proved that microorganisms can also be beneficial to human life. The wide variety of microorganisms that are found everywhere are most well…

Lens Fiber Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used…
