Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
Xylem is specialized to conduct water and dissolved minerals, and phloem is specialized to conduct organic nutrients and hormones. Certain vascular plants are seedless (ferns). They were very large and abundant
Inorganic ions are charged particles that do not contain carbon atoms bonded together. While organisms are mainly built from carbon-containing molecules, their functions rely on inorganic ions such as nitrate, hydrogen and calcium. This essay will detail some of the roles of specific ions and describe how animals, plants and bacteria use them. Productivity in an ecosystem in the soil is limited in part by the availability of fixed nitrogen in the soil. Nitrogen fixing bacteria in the roots of leguminous plants reduce atmospheric nitrogen to ammonium using ATP and reduced NAD.
This model could not be altered to include each of these processes because it would require additional items like soil, plants, and a larger jar. 3. How would the “weather” be affected if the water was at a decreased temperature? How would the “weather” be affected if the water temperature were increased? Answer = The weather would be calm in decreased temperatures because you don’t see condensation or evaporation happening when the temperature is cooler.
Fiber, also known as roughage, contains many properties that aid our digestion tract, and allow us to process waste products more efficiently. According to Nutrition.gov (2013) fiber can be found in many of our favorite foods including whole grains, vegetables, and fruits. There are two types of fiber, soluble and insoluble. Soluble fibers dissolve in water, and when digested, “form viscous solutions in the intestines” (Grosvenor & Smolin, 2006). “Fibers that cannot be digested by bacteria in the large intestines are called insoluble fibers because they do not dissolve in water.” (Grosvenor & Smolin, 2006) High fiber diets can produce many benefits, including higher nutrient absorption levels, and better waste output.
An anhydrous salt is a salt without the presence of water or any moisture. In this experiment the anhydrous salt was separated as well as the water from the hydrate. The mass of the anhydrous salt was one of the parts needed to be calculated in order to find the complete formula of the hydrate. The law of conservation of mass states that matter in a compound can be altered, separated, and pure substance can be destroyed, but the mass always remains the same. In this experiment, the hydrate was separated into water and the anhydrous salt.
The acid used in order to produce acetylsalicylic acid (aspirin) is acetic anhydride and there is no alcohol used so instead another acid called salicylic acid is substituted since it consists of the hydroxyl group. The correct ester name for aspirin is 2-acetyloxybenzoic acid. 5. In order to make the oil of the wintergreen odour, the substances salicylic acid and methanol are required in order to produce the methyl salicylate. However, the difference is the role in which it plays during the reaction since in wintergreen it is substituted as the carboxylic acid but in order to produce aspirin it is used as the alcohol.
5) What is the system where no roots stand out as the main one? A fibrous root system. 6) Why are grassroots particularly useful? They hold the top soil in place, preventing erosion. 7) What is an organ system consisting of nodes (the points at which leaves are attached), and internodes (the stem segments
Since it is a plant it will help reduce the “green house” gases and pollution in the air, not to mention making a cleaner burning fuel source to replace gasoline and reduce the amount of pollution even more. The plant also does not take much soil space and can be grown in between other crops such as corn. Hemp as long roots so that it improves soil structure and replenishes soil with nutrients and nitrogen and helps control erosion of topsoil. Also, once harvested, any residue can act as eco-friendly manure. It is also a weed suppresser to prevent other weeds from growing because it grows so fast and densely, it blocks out sunlight to other weeds that are trying to grow.
The digestion and absorption of the nutrients we consume draw the negative materials from the body. The body’s temperature stays at the same level and its acid-base balance will be healthy. When not enough water is consumed, major health problems may arise, such as: Headaches, forgetfulness, inability to concentrate: Ninety percent of the brain is water. For this reason dehydration’s first symptoms appear in brain function. It isn’t necessary to take medicine for every headache that develops: Drinking water is often the cure.
