What are truffles? Truffles can be depicted as an edible gourmet mushroom that comes greatly prized and yet sought after by many food lovers. They can also be described as fungi that grow completely underground and have a symbiotic association with the roots of specific trees, mostly oaks. Truffles are known to have an overpowering, strong, earthy, delicate scent and provide an exceptional flavor and aroma to food. Though the truffle is mostly used in very small amounts, its flavor and aroma…

E-number food additives, their chemistry and role in food Since the dawn of time, humans had using several simpler and yet natural food preservation techniques such as preserving meat using salt, or immersing onions and cucumber in a jar of vinegar to keep the food fresh and last longer. The method of preserving food had been evolved over a significant period of time. (Heldman, 2003) Food additives are either a natural or synthetic substances which was added intentionally to food to improve the…

15. If true chemical bonds bind atoms together to form a molecule through electron sharing, what is special about a Hydrogen Bond that makes it not a true chemical bond? My Answer: B) Unequal distributions of the protons generates partial charges Correct Answer: A) Electrons are shared unequally between different atoms Why my answer was wrong: I did not realize that the answer says, “protons,” instead of, “electrons.” The protons are not distributed from the nucleus, because if they were, the…

Sexual reproduction is a type of reproduction in which two different cells combine, which create an offspring. When two cells called the egg for female, and sperm for male, combine and join together they create a new organism called a zygote. During meiosis, one diploid cell divides and makes four haploid sex cells. Meiosis has two divisions of the cytoplasm and the nucleus, the divisions are called Meiosis I and Meiosis II. Reproductive cells go through interphase before meiosis. “ A…

Purpose: Observe a compound light microscope to learn the names of its major parts. Research: Microscope is an essential tool for the study of small structures such as cells. The most common type of microscope is the bright-field microscope, used for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x.…

When you look at the ingredients of a food, do you see a lot of ingredients you wouldn’t expect? Do you wonder how food lasts so long? Both of these are done through food additives. They add nutrition, preserve the product, maintain consistency, and retain flavor and color. But they are also mostly artificial. Before the 1800’s, people would mostly grow and process their food by themselves. It wasn’t until after the civil war that the majority of people started working in factories and needed…

Why is biodiversity important to an ecosystem? Why is it so important that we have different species of animals living together? It is extremely important for different species to be living together, because they all rely on one another for survival. Including us humans, we rely on other species to survive. We don’t just rely on other species for survival, but evolution has driven us to evolve to adapt and live longer. In an ecosystem, there are habitats. In a habitat, there are populations…

Wolves had been missing in Yellowstone National Park for more than 70 years. As a result, the ecosystem of the Park had completely changed. Without any predator that threatened them, the number of deer had grown overreact, destroying vegetation and forcing other species to look elsewhere in order to survive. In 1995 they decided to reintroduce a small number of wolves. Only with their presence, the wolves managed to recover the entire ecosystem: from bears, foxes, eagles, otters, up to all kinds…

Genetically Modified Organisms (a.k.a GMOs) is a term used to represent organisms and crops created using biotechnology and genetic engineering. It involves generating a class of organisms by integrating genetic information from different species using recombinant DNA biotechnology. The first successful achievement in genetic engineering experiments using plants dates to the 1980 's1, 2, 3, where biotechnology introduced major approval of bacteria used to produce insulin for manufacturing in…

Title: Importance of photosynthesis in agriculture. Introduction: photosynthesis is the process by which plants and some bacteria convert energy from the sun into food or chemical energy, This is how plants survive. This is the chemical reaction that takes place inside the leaf of a plant. This is what makes plants green and healthy.Photosynthesis has a vital role in agriculture. It allows crops to turn energy from the sun into a food source it helps the growth of the crop. It provides…
