Block: 4 Answer questions on a separate piece of paper, labeling each section and question number, and then attach it to this page to hand-in. Carbohydrates
1. What is the difference between a monosaccharide and a disaccharide? Provide examples of each.
Monosaccharide: has only 1 monomer (simple sugar) ex. glucose
Disaccharide: has only 2 monomers (2 sugars bonded together) ex. table sugar 2. Why is a sugar considered an organic compound? organic compounds (ex. sugar) contain carbon,hydrogen, and oxygen atoms that are linked together to form a chain. Anything that is natural (from nature ie; mentioned elements) are organic. 3. What are the three elements found in all sugars? carbon, hydrogen, oxygen
The online study guides for the ACT/ SAT’s are exceptional because it allows the student with appropriate feedback as well as, how to achieve higher scores, statistics and performance of other high school students across North America who have already taken these tests. Team members and professionals have developed constructed lessons in the study guide so the student can achieve the maximu...
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
Carbohydrates are categorised in three many groups: Ø Monosaccharide – monomers and therefore contain single surgar. Ø Disaccharide – contain double sugars. Ø Polysaccharide – are large molecules containing many complex sugars. The general formula for carbohydrates is Cx(H20)y. Monosaccharides are white crystalline solids with low molecular mass and sweet tasting.
Organic products and non-organic products have been a subject of interest to me for a great amount of time because I have often questioned whether there really was a difference between the two types of products. I always wondered what the nutritional, economic, laborious, and pollution differences were, if any, in the creation of the two types of products. Through research, I have found several sources of information that allow me to determine more than a physical difference between the two. To start, labeling something as organic is specific and determined by the United States Department of Agriculture (USDA). The regulations set are extremely specific and it is relatively difficult to meet the standards.
Organic refers to the way agricultural products, food and fiber, are grown and processed. “It is an ecological system that at its core relies on a healthy rich soil to produce strong plants that resist pests and diseases. Organic farming prohibits the use of toxic and persistent chemicals in favor of more “earth-friendly” practices that work in harmony with nature. In the case of livestock, antibiotics are prohibited, opting instead for preventative measures for keeping animals healthy and productive. Organic production also prohibits the use of genetically modified organisms (GMO’s).” (Ameriorganic) To find organic products one must only look for the U.S. Department of Agriculture (USDA) seal. The seal certifies the product must be 95%
The carbohydrates in pollen are mainly polysaccharides like starch and cell wall material. The sugar fructose, gluc...
Where does organic food come from and what does organic mean. Many definitions can be found defining the term organic food. All definitions of the term organic include the production and certification process. According to the article Definition of Organic Food, “Organic foods are defined as those that are produced without the use of chemicals, including pesticides and fertilizers commonly used in cultivation and drugs, such as antibiotics and hormones given to commercial livestock” (Inc., 2008-2012). The organic system rejects all forms of synthetic...
Knowing the specifics about organic foods will help a person determine whether they would prefer to eat organically or non-organically. The term ‘organic’ is a label that indicates that the food has been produced through the appropriate approval methods (“Organic Standards”). There are certain requirements that must be met by the USDA-accredited certifying agent. This certifying agent approves these requirements before the food can be labeled as an organic food. Organic operations must protect natural resources, save biodiversity, and use only the approved substances.
My intructor says it is important to use the checklist for answering essay questions in order t make sure i get the most points possible for wgar i know. It's a bunch of stuff to memorize, but after analyzing the list carefully, i think she may be right. i do need to understand what the question is asking; otherwise i probably won't get any credit even if i know something about the topic. The best way to do this is to plan ny abswer and then show the grader both that i understand ewhat the question is asking me to do nd how i will answer it. The grader knows i know the anwer, and it provides a guide for mw to follow so i make sure i cover all the points and don't get off the subject. Major points should stand out so that
Organic foods are those grown without the use of growth hormones, antibiotics, synthetic pesticides, or chemical fertilizers. Genetically modifying crops is also not preformed in organic farming. Soil fertility can be maintained using crop rotation, cultivation practices, and cover crops. Natural fertilizers and pesticides are still considered to be included in organic farming (Winter & Davis, 2006). Products that are controlled with cultivation conditions rather than chemical-synthetic pesticides include organic products (Woese, Lange, Boess & Werner Bogl, 1999). The use of synthetic pesticides and materials falls under conventional farming. If the materials are on the National List of Allowed and Prohibited Substances, it can, however, be considered organic. A process that chemically changes a substance extracted from naturally occurring sources is considered a synthetic material (Winter & Davis, 2006).
Sup Point B: Organic food is different from conventional food in several ways. Organic food uses natural resources like manure and compost in to enrich the soil where food is being grown. Any form of chemicals such as pesticides are not permitted to be used in any form. Organic farmers use crop rotation to preserve the soil. Organic farmersdo not ...
The basic difference between organic foods and natural foods lie in the label. The label organic means that it is free from harmful heavy metals which are used during the production of food. There are some criteria for organic foods to be labelled as organic foods. They must be grown in the conditions labelled by USDA. Synthetic fertilizers, pesticides and insecticides must not be used. Toxic persistent pesticides, genetically modified food, antibiotics, growth hormones and sludge and irradiation are all prohibited according to the standards set by USDA. Whereas the advantages of using organic foods are animal welfare requirements, cows required to be on pasture for pasture season, lower levels of environmental pollution, audit trail from farm to table, certification and inspection for proper follow of rules and legal restrictions on allowable materials.
I put the survey on the SMARTBoard and used a “screen” to cover up the questions that we had not done yet. I then went over each question individually with the students. The students did well with asking questions about the meaning of words and asking me to give them examples. The students only needed to be reminded a few times that they needed to raise their had to ask questions.
Organic chemistry is the study of carbon and its compounds (Alcin). Carbon is less than one percent of all matter.Carbon is part of every living thing (Gangson). Carbon makes up eighteen percent of all the matter in living things. (Alcin). The average human body has about 16 kilograms of carbon in some form of this element. Carbon is a part of DNA and proteins. (Robertson).
What is the term of “Organic?” The term “organic” refers to the way farming foods are developed and prepared by farmers. Actually, organic foods are produced by farmers who use the conservation of soil and water to enhance environmental quality for future organic foods. Thus, organic foods have become increasingly these days because it helps people’ health benefits and gives people higher quality of foods. Some people do not want to buy organic foods because they feel organic foods are too expensive or simply are not aware that organic foods exist. However, according to many research studies, organic food is defined as healthy food. First of all, organic produces contain fewer pesticide residues. Secondly, natural produces are fresher than
