Questions and Problems: 1. Describe the type of meter movement used in analog meters. The current in the circuit is used in basic meters to measure the voltage drop or current in the circuit. The current passes through the coils of wires‚ which is then magnetized. Inside the apparatus‚ there is also a permanent magnet which opposes the magnetic field of the magnetized coil of wire that is connected to the pointer therefore‚ as we see in meters‚ the pointer moves. There is also a spring connected

What is yeast? To most people yeast is just something that is in the food that we eat; However to the scientific community yeast is much more then that. According to the Dictionary of Student Science yeast is a one-celled fungi that can cause the fermentation of carbohydrates‚ producing carbon dioxide and alcohol. ( ) Yeasts are found in the soil‚ in water‚ on the surface of plants‚ and on the skin of humans and other animals. Like other fungi‚ yeasts obtain food from the organic matter around

The purpose of Experiment 36 is to identify the anions present in an unknown solution based on the chemical reactions with various chlorides. In this experiment‚ Pb2+ was present in the unknown solution‚ while the presence Hg22+ is in doubt‚ and Ag+ is absent. To begin‚ the first part of the experiment involved analyzing the results from the experiment with the solution with equal volumes of AgNO3‚ Pb(NO3)2‚ and Hg2(NO3)2. Based on the results and observations obtained from the tests with the stock

water‚ it will affect the swimming speed of the paramecium. The various students groups have individual experiment of how dose NaCl affect swimming speed of Paramecium‚ but the experiment did not show the result clearly to students. Therefore‚ after they finish the presentation‚ most of the students want to find out the chemical NaCl increases swim speed of Paramecium. Experiment Design The experiment prediction is if we add 4mL of Paramecium to 25mL of 0.2M NaCl and 225mL of Dryl’s solution‚ then Paramecium

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted

1- What are three risk and threats of the user domain? Top risks are users and social engineering 2- Why do the organizations have acceptable use policies (AUPs)? The AUPs is very important to any organization. The organizations should have AUPs to a- Protect the organizations from any attack weather from inside or outside. The organization can do that by preventing the employees from downloading any services not needed that may be come with threat such as virus or any kind of malware.
