Science The Mystery Of The Lost Colony - 1055 Words

Science Unravels the Mystery of the Lost Colony What makes history such an interesting subject to study are the many mysteries intertwined with in it. Over the years many of the mysteries have been solved. However, one of the most intriguing mysteries still remains unsolved and leaves us with a question that needs to be answered, what happened to the settlers of the Lost Colony of Roanoke? Since their disappearance historians have come up with multiple theories about what could have possibly happened. The most popular and widely accepted theory suggests that a hostile Native American tribe abducted the colonists and either killed them or made them slaves. An alternative theory suggests that the Spanish attacked the colony and killed the settlers. Another less credible, but still popular, theory is about the Dare Stones, a set of rocks that tell stories supposedly by the colonists which explain what happened to them. While all of these theories have some merit there are inconstanci es within them that make each of them false. A lack of information and technology is what caused the flaws in these theories and make incorrect. However, thanks to advancement in technology and new information a recent scientific study can prove what happened to the colonists of Roanoke. This new theory can be used to explain the disappearance of the hundreds of colonists and finally shed light on a mystery that is centuries old.

Amylase Trials free essay sample

Based upon your experimental results, write a paragraph discussing the relationship between environmental conditions and enzyme function. *There are many environmental factors these may include temperature because if its too cold the enzyme would still work but it would work slowly and if its too hot the enzyme will become denatured. As the temperature increases, the kinetic energy of the molecules increase so they move around more meaning that there are more collisions between the enzymes and substrates molecules and therefore more reactions. Ph is a factor because the different types of enzymes work best in different pH environments, a change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrates) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. Also changing the concentration of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions.

Based on this project, suggest a possible explanation for this medical concern. *Fever is often a response to an infection, illness, or some other cause; the hypothalamus may reset the body to a higher temperature. The substances that can cause fever are called pyrogens, which can come from inside the body or outside the body. Salivary amylase and pancreatic amylase are released by two accessory organs of the digestive system. In what structures do the enzymes actually chemically digest food? Based on the information you have learned about the digestive system, describe the optimal pH for the action of pancreatic amylase. Do classroom experimental results seem to support this finding? Why might there be differences?

Alzheimer`s Disease (1466 words) Essay Example For Students

Alzheimer`s Disease (1466 words) Essay Alzheimer`s DiseaseAlzheimers Disease is a progressive, degenerative disease that affects thebrain. Individuals with AD experience a progressive and specific loss ofcognitive function resulting from the differentiation of the limbic system,association neocortex, and basal forebrain. It is also accompanied by thedeposition of amyloid in plaques and cerebrovasculature, and the formation ofneurofibrillary tangles in neurons. Alois Alzheimer, a German doctor, diagnosedthis disease for the first time in 1907. At that time it was considered a raredisorder. Currently, this tragic brain disorder affects approximately fourmillion people; It is the most common type of dementia and the fourth leadingcause of death in the United States. Many studies have been done and are stillbeing conducted to determine the exact cause of AD. The molecular and biologicalbasis for the degeneration of neurons in AD is incompletely understood. However,the APP(Amyloid Precursor Protein) and its proteolytic fragmen ts have beenimplicated more often than not and is the focus of most current studies. Severallines of evidence have strengthened the amyloid hypothesis for AlzheimersDisease. The first being the identification of point mutations with the APP genein groups of patients afflicted with the familial forms of AD. Second, amyloiddeposition temporally precedes the formation of neurofibrillary changes. Inaddition, b-amyloid has been shown to be toxic to neurons. In AlzheimersDisease, b-Amyloid proteins derived from APP are the main component of neuriticplaques. It is believed that errantly processed APP derivatives may inducephysiological processes that lead to neurodegeneration and plague formation. Many studies have successfully linked APP with AD. One study on transgenic micewith human APP717(associated with familial AD) displayed subcellularneurodegeneration similar to those observed in AD, including dystrophic neurites,disruption of synaptic junction, and intracellular amyloid and reactive gliosis. Amyloid deposits in the tg mice were very similar to those found in AD and wasreadily recognized by anti-b-amyloid antibody. In other studies, Hippocampalpyramidal neurons in AD display an intense immunostaining with 10 differentantibodies against subsequences of APP. The area containing the stained neuronswere consistent with those showing the most neuropathology in AD. Collectively,these data show APP as being closely associated with neurodegeneration. However,it is still unclear if APP is the cause of cell death in the AD brain. APP couldbe one of many factors participating with differnent intracellular processes tocause cell death. In hope of finding more information on Alzheimers disease,researchers look for similarities and connections to other more understoodillnesses, one being the prion disease. This disorder is a neurodegenerativedisease characterized by prion protein deposits and is associated with reactiveastrocytes and microglial cells. Alzheimers disease is similarlycha racterized by plagues and inflammatory astrocytes. Many earlier studies foundthat prion peptides and b-amyloid proteins activate microglial cells bysecreting cytokines, reactive oxygen species, and other neurotoxins. Analogousto typical inflammatory signaling response such as those mediated throughclassical immune receptors, b-amyloid and prion proteins activate a commontyosine kinase-dependent pathway. This was indicated by an elevated level ofphosphotyrosine in plaque associated microglials of AD. Microglial treated withinhibitors of specific protein in the tyrosine kinase-based pathway successfullyblocked amyloid-stimulated secretion of neurotoxins and reduced the number ofcell death. Despite this documentation on amyloid-induced production ofneurotoxins, it does not resolve the issue of what causes AD. The speciesresponsible for neurodegeneration in AD still remain controversial. However, itdoes implicate b-amyloid peptide along with numerous coordinated responsepathways and med iating species. Neurodegeneration in AD is suspected to becaused by apoptosis or programmed cell death. Research with andenovirus-mediatedAPP gene transfer, demonstrate that neurons in vivo are vulnerable tointracellular accumulation of APP. Hippocampal pyramidal neurons show severeatrophy and nuclear DNA fragmentation, a typical feature of apoptosis. Infectionof rat hippocampal cells with an adonovirus contain APP695 cDNA enhancedglutamate induced rise of intracellular Ca2+ concentration. Elevation of Ca2+level in the cellular compartment can cause activation of a numbersCa2+-dependent degradative processes, including apoptosis. Interestingly, one ofthe newly discovered apoptosis-linked genes encodes a Ca2+ bindingsite. The increase in intracellular level of Ca2+ could come from the impairmentof glucose transporters. Data from studies in AD shows that the transporters forGlucose uptake, GLUT3, to be decreased. When glucose uptake is compromised, ATPproduction diminishes, Na/K+ pump s stops and the neuron depolarizes releasingglutamate. Large release of glutamate can cause a Ca2+ overload in the neuron. West Gallery and East Gallery EssayIn cells over expressing the mutant PS-1 L286V gene were extremely sensitive toapoptotic inducers. Data suggests that the PS-1 gene affects regulate freeradical metabolism and calcium homeostasis. Thus, cells expressing the PS-1mutation are under oxidative stress and are more sensitive to an increase in b-Amyloidpeptides. It is uncertain whether b-Amyloid is the underlying cause ofAlzheimers Disease. Exposure of this peptide to cultured neurons has beenshown to cause extensive cellular degeneration. Ironically, b-Amyloid can alsobe detected in healthy non-demented subjects. It could be said that, inAlzheimers Disease, b-Amyloid promote cellular degeneration by working withmany endogenous systems. Classical immune receptors, ion homeostasis,anti-apoptotic proteins, anti-oxidants concentrations, lysosomal/endosomalsystem, and AchE are a few key cellular systems that were mentioned in thisreview. In individuals with a high risk for this disease, thes e systems arecompromised in an unkown fashion, thus, allowing b-Amyloid to assert a toxiceffect on the neuron.
