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

contrast the functions of alpha amylase in the production of ethanol‚ with another commodity enzyme called Chymosin that is a protease and is used in the cheese industry. The production of ethanol requires the breakdown of starch from a polymer to a monomer such as glucose. The three general process steps‚ gelatinization‚ liquefaction and saccharification are used in converting starch to dextrose. Firstly starch granules found in nature are resistant to enzymic breakdown thus the process of gelatinization

These waves are best around April and May because this is the time that the tropical cyclone and the East Coast Lows (ECL).

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
