Since the beginning of the 20th century plastic has become the most common material. Plastics play an important role in almost every aspect of human life. It is found in virtually everything these days; plastic is used to manufacture different products like furniture, beverage containers, toys, and food packages. What makes a lot of manufactured materials these days depends on plastic, because of its durability, lightweight, flexibility and it low cost. Also it can be easily molded into a…

FOOD COLORS INTRODUCTION: Through pigments we observe the different colors at each step of our lives, because the pigments can be found in each organism in the world and plants are the main producers. Pigments can be easily found in fruits, vegetables and flowers. It can also be found in skin, eyes and in other complex body parts. Natural and synthetic pigments are used in food, furniture, cosmetics and other products. Natural pigment plays an important part in photosynthesis. The food colors…

Hydraulic Fracturing for oil and natural gas is possibly one of the most misunderstood parts of drilling around. The term itself is almost as bad for some as racial slanders. Countries have banned the process and even some states such as Colorado have placed embargos on the process until more research is available. Environmental groups storm capitals at the sound of the word demanding more regulations. What many don’t realize is that the oil business has been using the same process for 70 years…

Futuristic: It is important for the taxpayers of the United States to consider the options of the oil drilling industry. Supported by the prior research and evaluation, the continuation of conventional oil drilling throughout the United States will not only improve its economical and environmental futuristic aspects, but will ensure the survival of the United State’s global dominance in the oil industry. OPEC has faced severe drops in profits from the competition of booming private American oil…

Introduction The NuvaRing is a contraceptive, and it prevents you from getting pregnant.

It is intended that you insert the ring between the first and the fifth day of your period. The first week is the ring not quite reliable, so using a…

Introduction As it is true with humans and most living organisms, plants grow throughout their life cycles. Plants undergo both primary and secondary growth, those being vertically and in girth, respectively. However, plant growth differs from human growth in that plant growth is the result of external factors such as optimal soil conditions, sunlight, water, as well as internal factors such as hormones. Hormones can be defined as molecular signals, which are produced in small amounts by one…

Analyzing the situation question 3, the players in Food, Inc. are the consumers, producers, political figures, and the farmers. Most of the consumers, including me are left naïve about where our food is coming from. Even though we are left in the dark, we as consumers are keeping the producers in business. The producers are cutting cost by finding loopholes in how they manufacture our food, loopholes like employing and exploiting illegal immigrants, feeding our beef, corn, and using ammonium…

In this modern world, plastic be the most used material for packaging in almost every industry. The word ‘plastic’ comes from the Greek plastikos which means easily shaped (Robertson, 2013). Plastic is the combination of many molecules that linked together as one long chain which made from polymers: poly (Greek) means many and meros (Greek) means part (Robertson, 2013). Raw materials of plastic are called feedstock which come from natural and synthetic resources, such as crude oil, natural gas,…

Coelogyne flaccida seed culture in vitro reveals that there are two pathways of asymbiotic seedling development from seeds. On one pathway, the seeds obtained from green capsules germinated readily asymbiotically in the nutrient medium supplemented with 0.5 – 2 mg/l NAA and IAA plus 15% coconut water and charcoal, 2 gm/l. During the usual germination process, the undifferentiated embryo of the seed produces a large number of protocorm-like bodies (PLBs) without forming the intermediate callus…
