imparts the characteristic color to certain blue-green algae. It also facilitates a reaction necessary to the survival of this species; we can follow the kinetics of this reaction by measuring the conversion of Substance X to Substance Y at various times during purification.” Techniques and methodologies for extracting the proteins and purifying Enzyme X are as follows: The blue-green tinted proteins in Enzyme X give a distinct color to algae. The proteins are contained in the cells‚ so the cells

Nevertheless‚ young specimens live in upper littoral between algae. The average fish density was 0.18 and 0.08 fish per 100m2 in sampling areas in the Gulf of Trieste‚ Northern Adriatic Sea. 2 Behavior They are mostly active at sunrise and sunset. They are doing underwater ‘flight’ over long distances‚ and

At my age‚ few people can genuinely claim that they have had a life-changing experience. And after a morning jog one Saturday morning‚ I became one of these fortunate people. Spending countless weekends in the park down near my house‚ I’ve always enjoyed jogging around the river the most.

Chapter 1 INTRODUCTION Situation Analysis Global warming‚ also known as the green house effect is a topic that has received much attention in recent years; yet our climate change is not a recent problem. It has been morphing over many years. What is increasing is the rate of change; it is accelerating due to the growth of the human population. The growth of our population has increased our use of fuel‚ land‚ and manufacturing. All of these are increasing emissions into our atmosphere that increases

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Biofuels – Alternative and Renewable Sources of Energy - Modified from Source: http://biofuel.org.uk/ BIOMASS Biomass can be termed as organic material which is derived from living or more “recently deceased” organisms. The most important feature of biomass is that it is a renewable source of energy unlike other natural resources like coal‚ petroleum and even nuclear fuel. Biomass itself is a renewable energy source because we can always grow more trees and crops‚ and waste will always exist
