is a major concern for policymakers‚ more so if it involves a marked and sudden increase of violent and property crime. Meanwhile‚ violent crime generally includes crime of violence such as murder‚ gang robbery with firearm‚ rape and sexual abuse. What is the main cause of crime and its imperative relationship to poverty? Such a question at first may seem unanswerable because we could never pin point the exact cause of such worldwide problems. Crime and poverty have been around from time was time

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many disks of spinach leaves float at the end of every ten minutes. Our main focused and question was how using different amount of concentration of sodium bicarbonate would affect the process

Yes‚ they could vote; but they were ineligible to hold most of the newly minted political offices and could not serve in the senate. That was the province of the patricians. In effect‚ they had paid dearly for a freedom that simply turned out to be an aristocracy. Since they had nothing‚ they became reliant on loans from the patrician class in order to try and rebuild their farms and lives. But the debtor’s laws were written in

The first pair of plates is then placed in the refrigerator ant the time is recorded at 6:05 p.m. as the start time. The end time will be after 1 hour has elapsed. The radius of the crystal are measured and recorded for both sets of pairs. Then the rate of diffusion for each molecule is calculated by converting the radius from millimeters to micrometers and dividing the resulting number by the number of minutes the plates were sitting. * Diffusion in liquid -room temperature water -crystal

lack of job opening in our society. Even those who are fresh graduates in college are hard to get job‚ mostly those graduated in college are jobless and they are vacant only in their house. This is the reason why Philippines tackles unemployment rate in economic crisis. Once‚ there are job openings that need many options and requirements‚ so other people are not qualified of it and they may experience hard getting a job. Also‚ because of unemployment crisis here in Philippines‚ mostly Filipino

Experiment 5B: Ketone Reduction Objective: Using sodium borohydride as a reducing agent‚ the ketone 4-tert-butylcyclohexane is reduced to its corresponding alcohol. It is purified through extraction techniques to give the cis and trans diasteromer products. Procedure: The procedure was followed as outlined in Mayo’s book for Experiment 5B with the following modifications: 1. Reagents and Equipment – The reaction will be on a scale of 2X what is described in the text. 2. Reagents and Equipment

they were poor and uneducated” (entry 10b). Immigrants from different countries couldn’t speak proper English so if they went to get an education or to learn about America’s culture‚ they would be turned down since they wouldn’t be able to understand what a teacher would be saying to them. A result of not having a proper understanding of English would be that they could walk into a job that could pay low money‚ so they would be very poor when working in America. But since many immigrants were willing
