CHAPTER 1 I. INTRODUCTION: Nowadays ‚people can’t oppose the boosting of the countless pests and insects that disturb our daily habits. Controlling of insects and pests is one of the main problems of most farmers and gardeners. So‚ instead of buying commercial and expensive inorganic insecticides‚ an alternative and economical insect repellant made up of the sap of euphorbia plant‚ garlic‚ and siling labuyo‚ all natural insecticides derived from different plants which could kill insects and pests

are single-celled‚ while others a multi-celled. They all contain chloroplasts. Have a rigid cell wall. Most move by mean of flagella. d. Fungi – Yeasts‚ molds‚ and mushrooms. Some are single celled but many are large‚ multicellular ogranisms. Live primarily on land. e. Protozoa – single-celled eukaryotes that are not algae or fungi. Found in both terrestrial and aquatic environments. Do not have a rigid cell wall. f. Multicellular paracites (worms) – Live at the expense

They are all organic compounds‚ they may resemble molecules which turn up elsewhere in plant structure or function‚ but they are not directly involved as nutrients or metabolites.

infections‚ but they only treat bacterial infections. Antibiotics are useless against viral infections (for example‚ the common cold) and fungal infections (such as ringworm). Introduction: Penicillin is a group of antibiotics derived from Penicillium fungi. Penicillin is a historically significant drug being the first antibiotic discovered. Penicillin is a Betalactam antibiotic and is used in the treatment of bacterial infections caused by susceptible‚ usually Gram-positive‚ organisms. Figure1: Core

“The Feasibility of Makahiya (Mimosa Pudica) plant as an Alternative Larvicide for Mosquito larvae” Chapter 1 Introduction Dengue is the most common arthropod-borne viral (arboviral) illness. It is transmitted by the mosquitoes of the genus Aedes which are widely distributed in tropical or sub-tropical countries particularly in the Philippines. The AedesAegypti Mosquitoes are the vectors of Dengue fever and the eggs have the ability to survive desiccation for long periods of time‚ allowing eggs

Malaysia is one of the countries with the most abundant types of tropical tree species available in nature. Woods and timber are important in the economic development of Malaysia especially in the import and export industry. One type of woods with such vital function is Leucaena leucocephala. It is a plant species with many branches and numerous clusters of flat pods that enveloped the seeds (Shelton et al.‚ 1994). L. leucocephala was first brought into Southeast Asia in the last few centuries by

The contribution of each enzyme in the metabolism of Uloric is not fully understood. The oxidation of the isobutyl side chain leads to the formation of four pharmacologically active hydroxy metabolites. In urine and feces‚ acyl glucuronide metabolites of Uloric (~35% of the

Advances in modern science have had great impacts on our ability to understand how matter and energy cycle throughout systems. The cycling throughout networks can be explained by the Law of Conservation of Matter and Energy‚ which states that matter and energy cannot be created or destroyed‚ only changed. This cycle applies to many things‚ such as energy cycling through a food web‚ carbon traveling through the biosphere in the carbon cycle‚ and the movement of energy and materials that are used during
