the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids‚ and nucleic acids (Sheeler & Bianchi‚ 1980). Proteins are made up of polymers of amino acids. The shape

Lab 3 – Homework 1. Purpose of today’s experiment: To determine the effect osmotic pressure might have on cellular membranes‚ specifically when beet slices are placed in NaCl solutions of varying concentrations. 2. Hypothesis: The osmolarity will directly increase with increasing NaCl concentrations. 3. Control = Distilled Water – this was present in all solutions 4. The independent variable – salinity of the 6 solutions; while predetermined‚ the NaCl concentrations varied from 0% to 15%.

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

disorders. Biological influences such as genes‚ neurotransmitter functioning and predisposition contribute exponentially to the development and maintenance of anxiety disorders. These biological dynamics influence when and how anxiety disorders emerge and begin to cause distress in the individual. An anxiety disorder is an “unfounded fear or anxiety that interferes with day-to-day functioning and produces clinically significant distress or life impairment” (Sue et al.‚ 2013‚ p.?).

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

General Psychology May 8‚ 2014 Biological Factors of Homelessness Sheila McKehnie said‚ “People who are homeless are not social inadequates. They are people without homes.” This illustrates the important point that we cannot dismiss a person’s human dignity simply because he or she lives on the street. On the contrary‚ we need to acknowledge their equality and think about the endless factors that could have put these people on the streets. There are many biological and social factors that can lead
