Seas and oceans provide various types of resources to human beings and habitats to numerous species of plants and animals. They play very important roles in the economy of a nation and its people. Still‚ the marine and coastal ecosystems are under severe stress due to human activities. Ocean Resources The ocean is one of Earth ’s most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It ’s used for transportation—both travel

The main aim of laboratory work with Escherichia coli and soil sample was to introduce students to bacterial growth in pure culture and soil microbial flora. The experiment of bacterial growth in pure culture using optical density

would be devastating effects not only in the biological sector but also the environmental and economical aspects. To avoid catastrophes among ecosystems‚ tests need to be performed in essence to keep the ecosystems from being harmed. If‚ for example‚ diatoms and dinoflagellates were to be removed from the food web due to certain chemical factors many organisms (mollusc larvae‚ copepods‚ etc) will not have a food supply therefore resulting in the extinction of many organisms. This leads to disruptions

SCOPE OF MICROBIOLOGY: What is Microbiology? | � Microbiology is the study of microorganisms� Microorganisms‚ roughly‚ are living things that are too small to be seen with the naked eye� Microorganisms cannot be distinguished phylogenetically from �macroorganisms� (see variety of microorganisms‚ below)� Microbiology is more a collection of techniques: aseptic technique‚ pure culture technique‚ microscopic observation of whole organisms‚ etc.� Microbiologists

Low-Impact Fiber-Reactive Dyes The sustainability of our environment is crucial in saving the livelihood of the people and the planet. Since we are all interdependent‚ we will all have to do our part in sustaining our environment for the future. We should always be questioning and doing more about it rather than just talking or ignoring the facts. Most of us do not realize the excessive use of resources we have taken advantage of over the years. Generations past have exploited our planet which

The combination of these biotic stresses led not only to the dinosaurs’ extinction‚ but the extinction of a variety of plants‚ marine reptiles‚ diatoms‚ dinoflagellates‚ and nannoplankton (Elewa et al. 2009).
