Explain the relationship between three aspects of science: hypothesis, research/experimentation, and theory. Solution The three methods of science hypothesis, research/experimentation, and theory are parts of scientific method. Hypothesis is a rational prediction of causation among various variables. hypothesis is an explanation which is based on limited evidence as a basis of future research. Research is the next step where the hypothesis is tested and studied. It allows to expand the current knowledge with a specific end goal. A refined hypothesis then becomes the theory.

Write a short essay explaining the four primary groups of production. Include in your explanation an example of each group as well as what we call the payment each group receives. Solution Four primary groups of production are four main factors of production which are a foundation of any productions. these four factors are land, labor, capital, and entrepreneurship. the first factor is Land that consists all type of natural resources used to create goods and services. examples : land, Gold, oil, forest, animal etc. Labor who transform these natural resources into usable resources. the value of labor depends on their skills and educations. to increase the productivity of firm owner trained their employees (labors) to become more skilled. capital includes buildings, tools, and machines that are labor usees to make outputs of the process. some examples are trucks, automated machines, computers, etc. entrepreneurship who create the idea and combine these all three factors of productions and makes a profit and increases the productivity of a country. payments to land and capital are rent, wages to labor, and profit to entrepreneurship..

Why didn\'t the government just arrange to have excess food commodities shipped to places where people didn\'t have enough to eat during the Great Depression?1.Transportation systems during the 1930\'s had basically shut down all over the country. Solution 2) is the correct option The government\'s goal, via the AAA, was to preserve the idea of a market economy for agricultural products, not just to feed the hungry. 1) is wrong as there is water transport by that time, 3) is wrong as there r some places where people Use to die due to hunger. 4) is wrong as they have the chance to export food grains, some other which dont get spoil for few months..

What is the method of action of aldehydes? They damage proteins They disrupt membranes and DNA They damage nucleic acids They inhibit enzymes. Solution Answer will be 2. Aldehydes disrupts membranes and DNA. Aldehydes like glutaraldehyde and formaldehyde involves a strong association with outer layer of bacterial cells, specifically with unprotonated amines present on the cell surface, representing reactive site. this inhibits transport through the cell leading to inhibition of substrate reaching to rhe enzymes. Action mechanism of aldehydes also include nucleic acid damage by alkylation of amino- , carboxyl- or hydroxyl- group of nucleic acid.

What are rubisco and RuBP? And what do they do? Briefly list 4 similarities in how ATP is made in mitochondria and in chloroplasts. A. How does the second law of thermodynamics explain why diffusion occurs across a membrane? B. Describe how oxidative phosphorylation, substrate-level phosphorylation, and photo phosphorylation differ in the way ATP is made. Solution RuBisCO , is an enzyme Which is used in the Calvin cycle for catalyzing the first step of carbon fixation, a process by which the atoms of atmospheric carbon dioxide are made available to organisms in the form of energy-rich molecules such as sucrose. RuBisCO catalyzes either the carboxylation or oxygenation of ribulose-1,5-bisphosphate (also known as RuBP) with carbon dioxide or oxygen. Ribulose-1,5-bisphosphate (RuBP) is an important 5-carbon intermediate in the Calvin cycle taking place during photosynthesis. It is the substrate, which is used by the enzyme to fix CO2 to create a highly unstable 6 Carbon PO4 which decays into two molecules of glycerate 3- phosphate. In both i.e. Mitochindria as well as in Chloroplast ATP synthesis takes place via a proton gradient- Both have ATP synthatases Both have Electron Transport Chains Both have 70s ribosomes. The second law is a trend towards the randimization or increasing entropy. When the concentration of a substance on both sides of a membrane are equal, the distribution is more random than when they are unequal. Diffusion of a substance to a region, where it is initially less concentrated increases entropy, making it energetically favourable (SPONTANEOUS) process. -Substrate level phosphorylation occurs in the cytoplasm during Glycolysis and Mitochondria during Krebs cycle. -2ATP/GTP are produced by conversion of ADP or GDP OXIDATIVE PHOSPHORYLATION -Occurs in Mitochondria Occurs during respiration pigment systems are not involved ATP is produced from ADP and iP Molecular O2 is required for terminal oxidation. PHOTOPHOSPHORYLATION Occurs during photosynthesis inside the chloroplasts. Pigment systemt I & II are involved Sunlight is the external source of energy Molecular Oxygen is not required.

Virtual Machines: Discuss what are the new innovation today in this area and what effect this area have on the computer field. Look up information on websites then post the links at the bottom of your answer. How will this area change in the future? Will this area change society? Solution A virtual machine (VM) is an operating system (OS) or application environment that is installed on software, which imitates dedicated hardware. The end user has the same experience on a virtual machine as they would have on dedicated hardware. Virtualization does, however, require more bandwidth, storage and processing capacity than a traditional server or desktop if the physical hardware is going to host multiple running virtual machines. VMs can easily move, be copied and reassigned between host servers to optimize hardware resource utilization. Several vendors offer virtual machine software, but two main vendors dominate in the marketplace: VMware and Microsoft. VMware has a mature product portfolio, with many years of use in the IT industry. While a bit of a late player to virtualization, Microsoft is showing considerable progress. A classical example of VM which we use is Java Virtual Machine (JVM). The goal of a Java Virtual Machine (JVM) is to provide a runtime space for a set of Java code to run on any operating system staged on any hardware platform without needing to make code changes to accommodate the different operating systems or hardware. Another important application of VM is in Mainframes. Hypervisor, a variant of VM is used in providing many machines (called as Partitions in Mainframes) to outside world. Interesting application of VM is in Cloud Computing. A cloud is built up of numerous physical machines (the hardware). Each of these machines then run multiple virtual machines, which is what are presented to the end-users. Virtual machines are only limited in the way that their specifications cannot exceed that of their host (the underlying physical machine). There are exceptions to this as well, for example Amazon EC2 does the storage offline, so in that case it would be possible to request drive space that exceeds the host, but again not exceeding the physical size of the actual place where the storage is done. The security is the main issue in case of Virtual Machines and a lot of research is going on in this area. With newer technolgies like Internet Of Things(IOT), Machine Learning and huge amount of data to analyse VM role will further increase in the coming days. Concept of VM has destroyed the business of big companies like EMC, Dell, IBM, HP... in the sense like the small startups who had no option other than purchasing big boxes from these companies are now using the cloud service to store the data which inturn uses VM concept. ------------------- Sorry, I cannot give links here as it is againsr the Chegg Policy.

Hello! I\'m trying to build a command line interpreter simulator using C programming language, working in the linux environment. I don\'t want to get in to designing the whole thing, I just want a little help with a particular problem. This particular problem is how do I write a line or lines in C that will run a command as if I had typed it in the terminal? More specifically, the command I\'m trying to run is \"help.\" The command that shows all available commands. So for example, I want to simulate the \"ls\" command, the command that lists the content of the current directory. I would go into my editor and type this: #include #include int main() { system(\"ls\"); return 0; } Now if I go into the terminal, compile that program and run it, it\'ll display the content of the current directory as would simply typing in \"ls\" in the terminal. The problem is, I can\'t manage to do the same for the \"help\" command. After researching a bit, I\'ve found that the sh shell is looking in /bin and /usr/bin to execute \"help.\" However, that command is in neither directory and will ultimately let me know that the command is \"not found.\" If it\'s not in the earlier mentioned directories, then where could it be? Is it even possible to run \"help\" within a C program? Sorry if it\'s a little long, I just wanted to be as clear as I can be. Any help would be greatly appreciated! Solution you need to us , system (\"/bin/ls\"); Below is the update ******************************************************* Also , you can use the below program to list the directories,.

Part T:Hyarates Hydrates are crystalline compounds in which one or more molecules of water are combined with each formula unit of a salt. The water is not bound tightly and can usually be driven off by subjecting the crystals to the hottest flame of a Bunsen burner for 5 to 10 minutes. If the hydrate is colored, a color change usually results upon heating as the anhydrous salt forms. For example the following change occurs upon heating: CuSO4·5H2O (s) bright blue CuSO4 (s)+5 HO (g) white A generalized form of this reaction is: CuS 04.xH2O(s) CuSO4 (s) + x H2O(g) Recall that the percentage of a component in a compound is calculated by: (Part/whole) x 100=% Preliminary Questions (5 p Describe how you could find the % by mass of water in the hydrate CuSO4·5H20 assuming that yo did not already know the formula.

I/O redirection in C shell Please implement input / output redirection in the code posted below. Here are the specs: Your shell will need to support file redirection. Use the same syntax as defined in the Bash shell: a single \'>\' implies that one needs to redirect the standard output of the program being started to the referenced file while a single \'<\' implies the same with standard input. The double \'>>\' implies that standard output will append to an existing file rather than create a new file (similar behavior is required for the \'<<\' operator and standard input). You do not need to implement support for the Bash pipeline operator \'|\'. Before calling exec to begin execution, the child process may have to close stdin (file desriptor 0) and/or stdout (file descriptor 0), open the corresponding file and use the dup2 system call to make it the appropriate file descriptor. Don\'t forget to use the close system call to close the old file descriptor. #include #include #include #include #include #include using namespace std; int change_dir(char* args[]) { if (args[1] == NULL) { chdir(getenv(\"HOME\")); return 1; } else { if (chdir(args[1]) == -1) { cout << \"No such directory\" << args[1]; return -1; } } return 0; } int helper_func(char* args[]) { cout << \"Builtin commands so far are; cd, and help.\ \"; return 0; } int main() { while(true) { cout << \"$ \"; char cmd[128]; cin.getline(cmd,128); vector args; char *line = strtok(cmd, \" \"); char *tmp = line; while (tmp != NULL) { args.push_back(tmp); tmp = strtok(NULL, \" \"); } char** argv = new char*[args.size() + 1]; for (int i = 0; i < args.size(); i++) argv[i] = args[i]; argv[args.size()] = NULL; if (strcmp(cmd, \"exit\") == 0) { { exit(0); } } //else if (strcmp(args[0], \"cd\") == 0) change_dir(args); if (strcmp(cmd, \"cd\") == 0) { change_dir(argv); } if (strcmp(cmd, \"help\") == 0) { helper_func(argv); } else { pid_t pid; pid_t wpid; int status; pid = fork(); if (pid == 0) { if (execvp(args[0], argv) == -1) { perror(\"cmd\"); } exit(EXIT_FAILURE); } else if (pid < 0) { perror(\"cmd\"); } { do { wpid = waitpid(pid, &status, WUNTRACED); } while (!WIFEXITED(status) && !WIFSIGNALED(status)); } } } signal(SIGINT, SIG_IGN); signal(SIGTERM, SIG_DFL); return 0; } Solution #include #include #include #include #include #include using namespace std; int change_dir(char* args[]) { if (args[1] == NULL) { chdir(getenv(\"HOME\")); return 1; } else { if (chdir(args[1]) == -1) { cout << \"No such directory\" << args[1]; return -1; } } return 0; } int helper_func(char* args[]) { cout << \"Builtin commands so far are; cd, and help.\ \"; return 0; } int main() { while(true) { cout << \"$ \"; char cmd[128]; cin.getline(cmd,128); vector args; char *line = strtok(cmd, \" \"); char *tmp = line; while (tmp != NULL) { args.push_back(tmp); tmp = strtok(NULL, \" \"); } char** argv = new char*[args.size() + 1]; for (int i = 0; i < args.size(); i++) argv[i] = args[i]; argv[args.size()] = NULL; if (strcmp(cmd, \.
