  • Ideal Gas Law Experiment

    methods. A flask will be filled to its max capacity and then filled with that gas. After that, the ideal gas law will be used to find mm (the molecular mass of a substance). The equation will be changed to mm=gRT/PV instead of the usual PV=nRT. There are several gas laws exhibited in this experiment. Dalton’s Law of Partial Pressures allows us to determine the pressure of the gas by subtracting the water vapor pressure from the total pressure of the flask. The total pressure would be the barometric pressure for the day and the water vapor pressure would vary with the temperature. The ideal gas law (PV = nRT) is…

  • Miley Cyrus Crash Reaction Paper

    The substances found on the victims of the crash can be easily identified through simple math. You start by taking the percent values of each element found in the substance and changing it to grams, where one percent equals one gram, so that each element is out of one hundred grams. After finding the grams, you find out the moles of each element by multiplying the gram amounts by the conversion factor, which is 1 mol over the molar mass of the element you are dealing with, 12.01 grams for…

  • Enzymes And Endothermic Reaction

    engineering, mass production of protein and enzymes has become feasible. Use of enzymes is environmentally friendly as they catalyse reactions under mild conditions against polluting inorganic catalysts which works in the extremes of pH and temperature. However, this can be disadvantageous as enzymes can lose their structure and catalytic activity at process conditions that might be necessary for other components. This often becomes a constraint in using them commercially. Increase in stability…

  • Hematopoisesis In Zebrafish

    1.6.3 Hematopoisesis in zebrafish Within the past two decades, the zebrafish (Danio rerio) has become an excellent model to study the development of hematopoietic stem cells (HSCs). The genes and molecular signaling pathways controlling hematopoiesis are highly conserved between fish and mammals. Both share all major blood cell types that are generated from common lineages of hematopoietic stem cells [13]. This is an important advantage over invertebrate models that lack the complex…

  • Analysis B Bigemina

    3. Results 3.1 Cloning and phylogenetic analysis B. bigemina Argentina strain was used to obtain genomic and cDNA for PCR with primers BbigAMA-1 F and R to amplify the AMA-1 gene. The sequences had an identical length from both templates and of the estimated size according to primers' design (not shown). The nucleotide sequencing analysis presented a 1988-bp long gene (gene bank accession number: AB481200) and encoded a 595-amino acid peptide (gene bank accession number: BAH22706) (Fig. 1)…

  • Relationship Between Fluid And Newtonian Fluid

    electrically conducting, viscous incompressible fluid is ρC_P [∂T/∂t+(q ̅.∇)T]=K∇^2 T+μ(1+1/γ) (1.3) where =2[(∂u/∂x)^2+(∂v/∂y)^2+(∂w/∂z)^2 ]+(∂v/∂x+∂u/∂y)^2+(∂w/∂y+∂v/∂z)^2+(∂u/∂z+∂w/∂x)^2 is the dissipation function which represents the time rate at which energy is being dissipated per unit volume through the action of viscosity. Here, u,v and w are the velocity components of the fluid along thex,y and z directions respectively.C_P is the specific heat at constant pressure, T is the…

  • Empirical Formula Lab Report Essay

    practice calculating mass percent composition. Before beginning taking measurements, read through the instructions below and make a neat table in which to record all the numerical data. Using tongs put a clean crucible on the hotplate. Heat the crucible for approximately 5 minutes. Turn off the hotplate. Carefully remove the crucible to a piece of wire gauze and allow the crucible to cool for one minute. Transfer the crucible to a desiccator and allow to cool for approximately 5 minutes or until…

  • Conclusion Of Cell Transport Permeability

    lysosomes (Derrickson 72). The first experiment involves a simulation of simple diffusion. Other solutes dissolve in water, it is tested using the dialysis membranes all having different MWCOs (Molecular Weight Cut Offs), which is defined as the size of the pores of the membranes. The smaller the pores diameter gets, the smaller the number gets. The second experiment involves a different simulation that tests for the rate of facilitated diffusion, which also uses the dialysis membranes but also…

  • Polymerase Chain Report

    The random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) method was used to examine the genetic variability of Aiolopus thalassinus (Fabr.) populations at heavy metal polluted and unpolluted locations of different geographical distances. Four primers yielded a total of 69 scorable bands, which are all polymorphic. Cluster and Principal component analysis separated the inside and outside Cairo populations into two main branches that were further separated into smaller ones,…

  • Genetic Engineering In Medicine

    Genetic engineering, also called genetic modification is the direct manipulation of an organism’s genome using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the…
