...CHAPTER I INTRODUCTION Background of the Study Dyes are commonly used in our industry. Many dyes are too expensive and that is why many people find ways to have a cheaper one. Syzygium Aqueum or locally known as Tambis is a common tree in the Philippines and some part of Asia. The seeds of this tree have been found out by the researcher that it has biological active compounds of tannins which are needed in producing dyes. In this study, the researcher concluded that the leaves extract also of the said tree may possibly contain also a biological active compound of tannin which will be use as the raw material in producing dyes. Thus, this will be a great help to people in many ways such as drawing activities, colouring activities, and etc. Statement of the Problem This study aims to answer these following questions; 1. Is there any significant difference between the color of the extract of Tambis leaves from Turmeric Rhizome dye? 2. Is there any significant difference between the effectiveness of Tambis leaves extract from Turmeric Rhizome dye? 3. Is there any significant difference between its long lasting effects of Tambis leaves from Turmeric Rhizome dye? Significant of the Study In this study, extracting the tannin from the leaves of Tambis tree will be used as the raw material in producing dyes. Conducting this study will help people minimize buying high cost dyes; instead choose the leaves of Syzygium Aqueum as dyes. Scope and Delimitation ...

...Sexual selection in fish inhabiting great lakes Sexual selection plays an important role in the animal kingdom as it can act as a driving force for evolution. Darwin describes sexual selection as depending on “the advantage which certain individuals have over other individuals of the same sex and species solely in respect to reproduction” (Darwin, 1871). This can be interpreted as intraspecific reproductive competition where typically there is a rivalry between males for obtainment of the female. This type of competition can cause drastic changes in behaviour and appearance in males in order to get the attention of the female. The reasons behind female choice have been debated since the days of Darwin but most believe that a female will prefer...

...Food Additives: Food Colorings and Flavorings Are They Healthy of Unhealthy? What are food additives? What are food colorings? What are food flavorings? Are they healthy or unhealthy for us? These are all questions that will be answered throughout this paper. I will go into deep detail about what these things are and where they come from. Also, we will see if these things are healthy or unhealthy for our bodies. After knowing answering all these questions, you will leave educated knowing more about what you may eat every day. First, I will go into detail about what food additives consist of. In general, food additives are substances that are added to food. These substances either make food look or taste better to the public. Also, there are substances that are added to food to keep it safe and clean from pesticides and other processes. Food additives can consist of two categories: direct and indirect. These are two ways of food additives getting inside our food and affecting the taste, smell, and safety of it. Direct food additives are substances added to food for a certain purpose. For example, xantham gum is added in food to make salad dressings, puddings, and things of that nature. Indirect food additives are substances that just finds their way into food during certain processes. For example, small amounts of chemicals from when food is processed and packaged finds its way in food while being stored. This is the reason why FDA requires food safety inspectors to inspect...

...than 6 mm. Males are distinguished from females by their smaller size, larger antennules, modified post-abdomen, and first legs, which are armed with a hook used in clasping.The genus Daphnia includes more than 100 known species of freshwater plankton organisms found around the world.They inhabit most types of standing freshwater except for extreme habitats, such as hot springs. All age classes are good swimmers and are mostly pelagic, i.e., found in the open water. They live as filter feeders, but some species may frequently be seen clinging to substrates such as water plants or even browsing over the bottom sediments of shallow ponds. Adults range from less than 1 mm to 5 mm in size, with the smaller species typically found in ponds or lakes with fish predation. The ecology of the genus Daphnia may be better known than the ecology of any other group of organisms .Daphnia feed on small, suspended particles in the water. They are suspension feeders (filter feeders). The food is gathered with the help of a filtering apparatus, consisting of the phylopods, which are flattened leaf-like legs that produce a water current. As the current flows anterior to posterior, the Daphnia collect particles that are transferred into the food groove by special setae. Although the feeding apparatus is so efficient that even bacteria can be collected, the food is usually made up of planktonic algae. Green algae are among the best food, and most laboratory experiments are done with either Scenedesmusor...

...Alexander Young Jackson was born October 3rd, 1882, In the family home which was located on Mackay street, Montreal, Jackson was the third of six children. When people think about Jackson they tend to see him as being a Quebec artist which is rightly so , but the roots of his family reached into Ontario and because of this his art life is identified as much with Ontario as Quebec. Jackson was early influenced by the works of James Wilson Morrice and owes something to the French Impressionists and Post Impressionists. Even thought Jackson work has been influenced Morrice and the French Impressionists and Post Impressionists . Jackson has alway maintained a definite personal quality to his art. Jackson has devoted himself exclusively to landscape painting. It has been the back country which appeals most to Jackson. We should be glad that he has vigorously recorded a section of Canada that is so inexhaustibly rich in character and is infinite in the variety of beauty. There is in everything that he paints an inherent devotion to his own ideals, and a constant striving to dig deeper and explore more fully the sublet and significant manifestation of the Canadian Scene. Jackson is a sublet colourist and an able teachician, but the most mark of index for Jackson identification is the lyrical rhythm and flow of his compositions and the directness with which he grasps the essentials. He knows better than most artists what to leave out and his pictures never carry an overburden of distracting...

...relationship defined? Explain how the presence of algae can indicate either pollution or productivity of a body of water. Algae are a very large and diverse group of eukaryotic organisms, ranging from unicellular genera such as Chlorella and the diatoms to multicellular forms such as the giant kelp. Most are autotrophic and lack many of the distinct cell and tissue types found in land plants such as stomata, xylem and phloem. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of algae that includes Spirogyra and the stoneworts. Algae has several uses in nature and for mankind. Agar is a jelly-like substance, obtained from algae, which is derived from red algae, has a number of commercial uses. It is a good medium on which to grow bacteria and fungi as most microorganisms cannot digest agar. Alginic acid, or alginate, is extracted from brown algae. Its uses range from gelling agents in food, to medical dressings. Alginic acid also has been used in the field of biotechnology as a biocompatible medium for cell encapsulation and cell immobilization. Molecular cuisine is also a user of the substance for its gelling properties, by which it becomes a delivery vehicle for flavors. Algae fuel or algal biofuel is an alternative to fossil fuel that uses algae as its source of natural deposits. Several companies and government agencies are funding efforts to reduce capital and operating costs and make...

...canvas. Both Echo Lake, Franconia Mountains, New Hampshire and Field of Poppies are landscape paintings depicting different subject matter within 30 years of each other. Echo Lake, Franconia Mountains, New Hampshire was created in 1861, during the transition between Romanticism and Realism, by Albert Bierstadt. This landscape is made with oil on canvas when Bierstadt went to visit New Hampshire, United States of America. Field of Poppies was created in 1890, during the French Impressionism, by Claude Monet. This landscape is made with oil on canvas during the summer in the poppy field near his house in Giverny. These two paintings shows what the artists saw in their surroundings from the lake to the mountain, and from the field to the trees. Both paintings depict how the artists demonstrate their own interpretation of the landscape in the late 1800s and early 1900s. Bierstadt’s Echo Lake, Franconia Mountains, New Hampshire retains the idealized, realistic view of the landscape by depicting every detail he sees compared to Monet’s Field of Poppies where the landscape strongly incorporates expressive brushwork, playful colors, and soft lighting. Both of the landscapes use oil on canvas allowing brushwork to either be visible or not. The slow drying oil allows artists to edit their paintings after the initial stroke of pigment that they place on the canvas, thus they can either add texture or smooth out the oil in their brushwork. For Bierstadt’s Echo Lake,...
