There are four biological marcomolecules essential to the function of a cell: lipids‚ proteins‚ carbohydrates and nucleic acids. Proteins are made up of amino acids that have a carbon in the center of the structure with four chemical groups attached to the sides. Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis

Introduction The objective of this experiment is to identify if the 12 provided solutions contain starch‚ glycogen‚ reducing sugars or proteins. The four major biological macromolecules are carbohydrates‚ lipids‚ proteins and nucleic acids. Abundant elements in the world such as carbon and nitrogen bond in different ways to form many different molecules. The functional groups are what determine their characteristics. During the experiment‚ there will be 3 test. The iodine test is completed to

The life cycle concept itself is not‚ of course‚ a new one‚ the biological life cycle having already been extended to organizational and product life cycles – and to teachers. In all cases‚ the cycles involve notions of conception‚ growth and development‚ maturity and eventual decline or withdrawal. Such a cycle is obvious

The primary objective of this experiment is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains

Whitney Barnes: SENSATION & PERCEPTION WORKSHEET a) Briefly describe the path of information from the targeted sensory organ (i.e. eye‚ ear‚ skin‚ etc.) to the brain. Include a synthesis of terms/information from both Chapter 2 - Biological Basis of Behavior and Chapter 3 - Sensation and Perception in your description. When you are using your ears you can choose what you want to listen to‚ but you cannot choose what you are hearing. The first step is when the pinna collects sounds that enter through
