Q2. Contingency Theory offers a better way of managing change than either the Classical or Human Relations approaches. Identify and discuss the different perspectives on managing change offered by Contingency Theory (Ch.3, 10), the Classical approach (Ch.2) and the Human Relations approach (Ch.3). Evaluate the benefits offered by Contingency Theory’s ability to adapt to situational factors.

VII. The Evolutionary Perspective  

A) Explain this way of thinking about human psychology.

B)This perspective is based on Darwin’s theory of evolution: Natural Selection. Explain natural selection by giving an example of an adaptive trait – one that promotes the ability of a species to adapt to its environment, survive and reproduce C) Inclusive fitness – explain this concept, and how it is used by evolutionary psychologists to explain human behavior

Identify a popular/common computer related product/solution that utilizes an interface that are not optimal for human interaction. It must clearly identify the original problem that lead to the development of the solution. Describe how the users resolve the problem before the solution was developed and after the development of the solution. Explain why you think the solution is not optimal and how to improve the solution to provide a better interface for human interaction.

Is a universal list of human rights that will be acceptable to all people in all societies possible? Can people in different countries agree on a common set of fundamental protections and guarantees for individuals? Consider parts of the Universal Declaration of Human Rights. What elements seem universal? Which, if any, do not? If a common set is not feasible, how can international organizations identify and sanction rights violators?

The below statements are true/False?

963.Sphingolipids play an important role in cardiac tissues.

962.Lung surfactant is a kind of phospholipid.

961.Acyl Carrier Protein (ACP) is specially used for fatty acid synthesis.

960.Carnitine is a carrier for fatty acid for transportation from the cytosol to the mitochondrial matrix.

959.Both even- and odd-carbon chain fatty acids are catabolized by beta-oxidation.

958.LDL uptake in cells is mediated by receptors.

957.Total cholesterol content in HDL is higher than that of LDL.

of benzoic acid, benzocaine, and biphenyl are given to students in a vial. Propose a detail separation scheme to isolate and purify each component in the mixture. Your scheme should include an acid-base extraction and purification, as well as any other necessary steps and laboratory techniques. You may use any of these given reagents (e.g., acids, bases) as needed in your separation scheme. Be specific in each reagent name and technique used in your separation scheme. The most efficient step of separation and purification chosen will receive the most credit.

Please be as specific as possible, do not just post answer.

The basic unit of life is the cell, and now in a modern laboratory even mammalian cells can be easily cultured in a test tube or a flask. In this unit you have learned about the biomolecules of life such as carbohydrates, lipids, proteins and nucleic acids which come together to allow cells to form and function. You are required to design a cell culture medium for maintaining mammalian cells, what are your key considerations? (hint: you need to describe the key nutrients and the underlying reason for them, and the pH of your medium).

Post-lab questions:
1. Provide the chemical structure of KHP, indicating the acidic hydrogen.  

2. Why is the solubility of KHP in water greater than many fatty acids with six or more carbons?

3. What is the chemical difference between saturated and unsaturated fats?   

4. How many moles of NaOH are in 26.7 mL of a 0.100 M NaOH solution?  

5. If the above volume of NaOH was required to titrate a fatty acid solution containing 0.753 g of an unknown fatty acid, what is the molar mass of the fatty acid?
