Routine activity theory is a sub-field of rational choice[->0] and criminology[->1]‚ developed by Marcus Felson[->2] and Lawrence E. Cohen[->3]. Routine activity theory says that crime[->4] is normal and depends on the opportunities available. If a target is not protected enough‚ and if the reward is worth it‚ crime will happen. Crime does not need hardened offenders‚ super-predators‚ convicted felons or wicked people. Crime just needs an opportunity. The basic premise of routine activity theory

BIOLOGY IA A Factor That Will Affect Enzyme Activity The Question Effects on Enzyme activity: investigating the effects of mixing Hydrogen Peroxide with Catalase extracted from potatoes at different temperatures‚ and then comparing the results with the same method‚ except to replace the Potato juice with MnO2 Hypothesis Since enzymes are a type of protein‚ they will be destroyed at high temperatures and activity rates will go down at low temperatures. Also‚ if done at low temperature

Activity-Based Costing (ABC) is when you figure out the cost of activities to then discover the cost of products and services. ABC occurs in in four stages. These steps are as follows: identify activities and calculate their estimated total costs‚ identify the allocation base for each activity and estimate the total quantity of each allocation base‚ compute the predetermined overhead allocation rate for every activity‚ and allocate indirect costs to the cost object. I will use the production of a

temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity‚ shown as the last point

Enzymes also known as catalysts is one of the main factors in producing energy in individual’s bodies. The experiment conducted was to test how different temperatures effected the catabolizing of fungal and bacterial amylase‚ as well as the optimal temperature needed for the enzyme to correlate with the bacteria and fungi

catalase activity The extent at which environmental factors affect the rate of catalase activity was discovered in this lab. The assay system‚ in which a filter paper disc was dipped into the enzyme and submerged using a stirring rod in a test tube filled with 20mL of hydrogen peroxide‚ was used to test several enzyme factors. As the saturation of hydrogen peroxide increased the rate of reaction increased as well. When the enzyme concentration increased the rate of catalase activity increased

Chemical monitoring and management assists in providing safe water for human use and to protect the habitats of other organisms Identify that water quality can be determined by considering: * concentrations of common ions * total dissolved solids * hardness * turbidity * acidity * dissolved oxygen and biochemical oxygen demand Water quality is commonly defined by its physical‚ chemical‚ biological and aesthetic (appearance and

Sometimes‚ people that are younger than the age of 18 have good political opinions as well. Those teenagers are left unheard‚ because they are not of legal age for political voting when it comes to electing a president. Denying them the right to vote denies them a voice in our democracy. Most people around me believe that the voting age should also be lowered‚ and each of them care more about politics than most of the adults we know. If teenagers were able to vote‚ then there wouldn’t be a controversial

manuscript. (Page 8‚ line 13-15) Comment 14: Page 8: Explain if pH was controlled during fermentation. In any case‚ do a reference in the result section to the pH at the end of fermentation Response: The pH was not directly controlled during the fermentation. In the line with typical studies conducted for ABE production‚ the medium was supplemented with buffer (50 g/L KH2PO4‚ 50 g/L K2HPO4‚ 220 g/L C2H3O2NH4) as an approach to control the pH changes during the fermentation. In addition‚ it has been reported
