Unlike carbohydrates‚ proteins and lipids are similar and contain monomers to make polymers. Unlike lipids‚ carbohydrates and proteins make up a larger group of molecules called macromolecules. Unlike proteins‚ carbohydrates and lipids are macronutrients. Proteins and carbohydrates differ slightly based on their chemical

DNA was removed from bananas that had been blended with water in order to examine how DNA is seen from the naked eye. DNA stands for deoxyribonucleic acid‚ which is a nucleic acid that contains the sugar deoxyribose. DNA is made up of a series of monomers called nucleotides. Each nucleotide has three parts: a deoxyribose molecule‚ a phosphate group‚ and a nitrogenous base. In addition‚ there are four kinds of nitrogenous bases in DNA. Two of the nitrogenous bases‚ adenine and guanine‚ belong to

It claims that life started when a group of chemicals mixed together to form a pond‚ making amino acids‚ which then lead to proteins‚ and later the first forms of life. The evidence presented in the Miller-Urey experiment provided proof that basic monomers could be created from a mixture of methane‚ ammonia‚ and hydrogen. Different to the Primordial Soup Hypothesis‚ the Iron-Sulfur World Hypothesis states that the first cells that existed on Earth were enclosed in metals. The lipid present in the

Definition/comparison questions Evolution / Selection Evolution is a slow continuous process of change that happens in plants and animals over a long period of time resulting in a change from simpler to more complex forms. This is the reason modern day plants and animals are different from those of past. The competition for resources will favour organisms with better adaptability and certain variations over others hence leading to change in the rate of occurrence of certain traits within that population

Spandex fibers were first produced by Farbenfabriken Bayer. He was a pioneer in polymer chemistry and in 1952 earned a German patent for his synthesis. The final development of spandex was produced by scientists at Du Pont and the U.S. rubber Company. Du Pont used the brand name Lycra. They soon began manufacturing in 1962. Du Pont is the world’s leader in spandex production. Spandex development first started in during World War II as a substitute for rubber. Since rubber was being used for the
