THE ECONOMY The economy of Pompeii owed much to two factors‚ the fertility of the Campanian soil and the town’s position as the harbour for the surrounding region. Wall paintings indicate that a wide range of fruits and vegetables were grown in the region. In these‚ as in grain the city would have been self-sufficient. The two most significant agricultural products were undoubtedly wine and olive oil. Both of these were widely exported and they must have contributed greatly to the wealth

Economic factor affected in Tajikistan: Tajikistan has grown a lot since 1997. The ongoing privatising of small and large businesses and factories still provides for an enormous growth. More and more people return to their homeland‚ since there is peace and the threat connected to war has gone. In the second part of 1997‚ the macroeconomics came to balance. Trade was extended‚ and the prices were no longer controlled by the state. The budget holes were reduced to a minimum‚ and the regular

membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living beet roots were then placed in water and exposed to various temperatures. A sample of the water that the beets were in was taken and absorbance was determined by the spectrophotometer and concentration from the standard curve for betacyanin. Findings: In

use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions: 1. Describe
Premium Chlorophyll Photosynthesis
INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components

Examine the factors affecting power relationships and the division of labour between couples. (24 marks) Introduction: You need to explain that there are a variety of factors that can affect power relationships and the division of labour between couples. The division of labour refers to the roles men and women play in relation to housework‚ childcare and paid work. Sociologists are interested in whether these tasks are shared equally.t Examine the factors affecting power relationships and the
