Petri dish

The animals that are used for experiments go through horrible tests. According to PETA scientists will “breeds dozens of monkeys every year to be prone to mental illness. Half of the babies are torn away from their mothers in order to inflict mental trauma on them, and they’re never allowed to see each other again. These babies suffer from horrible fear, anxiety, and depression. Their misery leads to hair loss, diarrhea, and even self-mutilation.” In other experiments PETA says that some farming…

Nowadays, due to an up rise in technology, a new way to produce a child has been found. This method to make a child is described by a joint between an egg and a sperm inside a Petri dish free of love and sentiments. This way of creating a clone is devaluing human lives and is known to be a grim scenario because it sacrifices a thousand human lives in order to experiment. Human life is no more treated as a special gift, but it is…

Are antibiotics overprescribed? Many people around the world are victims of bacterial antibiotic resistance. This is a result of doctors overprescribing antibiotics when unnecessary. Many antibiotics are prescribed for illnesses that caused by viruses. Doctors grab their prescription pad, when symptoms of common infection are shown in their patients, as there is no accurate diagnostic testing for bacterial infections. Bacteria become resistant to antibiotics through overexposure. On the other…

into each 12-L cages, with this relatively low density to avoid effects of crowding on longevity and mating performance. All cages were of clear plastic with a mesh-covered window (ca. 80cm2) for ventilation. No calling, courting, or mating were observed in cages prior to separating the sexes. A L12:D12 h photoperiod was maintained, with flies also experiencing a simulated dawn and dusk as the lights ramped up and down through an additional 1 h at the beginning and end of the light phase. 2.4.2…

The Effect of pH levels on the Motility of Daphnia in Lake Ecosystems Introduction: The production, transportation, and use of chemicals by chemical industries can result in chemical pollution. This leads to a harmful effect on ecosystems and their balance of life (Linlin, Chen, 2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also…

Ali Alhasoon Dr. Jessica Oxendine English 1301 October, 2017 ANIMAL TESTING Animals have been companions to humans for centuries. Animals help us farm more efficiently, reach far places by riding on them, and we even used them for food when required. Since ancient times scientists also experimented on animals to test new techniques of treatment(Of mice and men: the evolution of animal welfare guidelines for cancer research). Evaluating new chemical to potentially cure diseases and help people…

politicians supported the private banking despised a central banking institution. The idea of having a central bank that would control the finances and lending nationwide fueled national debate. Many believed the Bank of the United States was a petri dish of corruption and government control. One could easily take sides with the people who were opposed to the Bank of the United States, yet the necessity for a national bank was demonstrated by inflation, corruption, and economic hardships.…

We placed the C.Volutator in a petri dish and we observed them under the dissecting scope. We made sure to separate them by sex and by sampling method in order to observe the difference in body lengths. Once we placed them on the slides we then placed the slide on the projection scope.…

four simple steps. In the first step, called “spot seeding”, specific cells are placed in specific concentrations in a petri dishes without the need for any external matrix components (NASA 4). The cells must then undergo a brief incubation period, allowing the cells to mature (NASA 4). The culture is rinsed, removing all unattached cells and a growth medium is applied to the dish. The final step, provided in the patent, requires the “periphery of the spot to proliferate [allowing for…

Cell culture & cell counting: Introduction: Cell culture is the method of removal of cells from their respective animal or plant source, followed by their growth in a favourable artificial environment. These cells can be removed directly from tissues or fragmented using enzymatic or mechanical method. These cells can be obtained from the already established cell line or cell strain. Short protocol:In this protocol, initially cells were washed to remove adherent cells, incubated and…
