DIFFUSION AND OSMOSIS: WHAT’S TO EXPECT? Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment

TITLE: The Amount of Protein in Chicken Tissues over Cooked Various Periods of Time. ABSTRACT: In this lab‚ we are using a BioRad protein assay dye to determine the concentration of protein in our chicken. The dye binds to the amino acid residues‚ which allow us to find the concentration of protein (BioRad Protein Assay for Tissues). Our hypothesis was the longer chicken is cooked the less protein is available. To test our hypothesis‚ we made samples using our chicken and distilled water to determine

1. Most people think that advertising works in general‚ but that it doesn’t not work on them in particular. “ It works on most people‚ but it doesn’t work on me?” What biases might be behind such a belief? This could be related to hindsight bias 2. Explain in your own words‚ what the continued influence effect is. Give an example‚ different from the ones used in the book The continued influence effect refers to the way false claims enter someone’s head and continue to influence their beliefs

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol

solutes move via passive diffusion through the plasma membrane. Diffusion is a process where molecules move from an area of high concentration to an area of low concentration. How quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances

Protein biosynthesis is the process by which biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. Translation‚ the assembly of proteins by ribosomes‚ is an essential part of the biosynthetic pathway‚ along with generation of messenger RNA (mRNA)‚ aminoacylation of transfer RNA (tRNA)‚ co-translational transport‚ and post-translational modification. Protein biosynthesis is strictly regulated at multiple steps‚ and error-checking mechanisms

storm roars above us as it prepares to rain down upon us again‚ but that’s not what baffles me. There’s an extremely high pitch zipping sound in the air and it’s nothing like I’ve ever heard before. Jet carriers are the source of the strange sound as they zoom at impossible speeds above us. The carriers are a streak of black on the city and what I can make out; they’re nothing like the carriers I’m used to. Normal carriers begin to land on the roofs tops in the distance and that’s why there’s an echoing

MGNT 3430: Operations Management Fall 2014 Homework 1 Answers Discussion Questions Q6 (p. 25). Although all nine of the competitive priorities discussed in this chapter are relevant to a company’s success in the marketplace‚ explain why a company should not necessarily try to excel in all of them. What determines the choice of the competitive priorities that a company should emphasize for its key processes? Answer. It is often not a good idea for a company to try to excel in all of the competitive
