Khanya Ramey Tuesday Nov. 24 Intermolecular Forces Intermolecular Forces Lab II. Goal: The central goal of this experiment is to depict the intermolecular forces of four different properties of solubility‚ evaporation‚ viscosity‚ and boiling point. The reason for achieving the goal is so we can further understand solubility‚ Evaporation‚ viscosity‚ and the boiling point of liquids. III. Experimental procedures In this Lab there were four different stations to experiment with‚ my partner and

Respiration: How Cells Harvest Chemical Energy 1. A cell must work just to maintain its complex structure‚ for order is intrinsically unstable. Because of entropy (the second law of thermodynamics)‚ which states that any enclosed system tends toward disorganization‚ cells must constantly use energy to keep themselves in order. If the cell was to stop using energy and let itself go then it would eventually get so disorganized that it wouldn’t function properly. 2. With the help of enzymes‚ the cell systematically

Will the current horizontal cabling suffice for the new network? If it will not‚ what type of cable should be used for the horizontal cabling? Provide detailed specifications for this cable. (10 points) The current horizontal cable will work with the new network. The only issue with the current cabling is there should be no cables laying on the floor. All

Molecular Cell Biology – Spring 2013 Study Guide – Exam #3 Protein Folding & Post-translational Modifications -What are post-translational modifications? - are modifications that a proteins undergoes to achieve its mature state. Such as cutting‚ folding‚ splicing and other processes. -How do proteins achieve their final conformation? - A protein achieves its final conformation by spontaneously folding. All the information that the protein needs as to how to fold is already located

. Na+ and K+. K+ was more concentrated inside the cell while Na+ was more concentrated outside the cell. 2. A cell is at rest without any implications of changing the potential. 3. 4. 5. K+ is more permeable than Na+ in a resting neuron. This is because there are few sodium leakage channels. 6. Since the resting membrane potential is the potential difference between the inside and outside of the cell across the membrane‚ a change would depend on the resting permeability of the membrane to ions.

Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee

DESMOSOME STRUCTURE & ITS FUNCTIONS | Bricks in a building must be stuck together and also tied somehow to the foundation. Similarly‚ cells within tissues and organs must be anchored to one another and attached to components of the extracellular matrix. Cells have developed several types of junctional complexes to serve these functions‚ and in each case‚ anchoring proteins extend
