Natalie Drossoyianni I.B 1 Psychology HL Discuss the use of technology in investigating cognitive processes. Technology has been very useful for the past few years in investigating cognitive process. With the use of neuro-imaging techniques‚ researchers can examine brain structure and function‚ and thus understand better the relationship between cognition and physiology. The basic neuro-imaging techniques are the PET‚ the MRI‚ and THE fMRI scan. The PET or else the positron emission tomography

Investigating the Limits of Cell Growth Background: To find factors that limit cell growth In multicellular organisms‚ In order for an organism to grow cells must divide through mitosis. Cell division happens after the cell is big enough so the daughter cells will be replicated without any flaws. The regulation and amount of materials that can enter and leave the cell is based on how large the cells surface area is. The rate of movement is also determined by the volume of the cell. Many factors like

Investigating Ratios of Areas and Volumes In this portfolio‚ I will be investigating the ratios of the areas and volumes formed from a curve in the form y = xn between two arbitrary parameters x = a and x = b‚ such that a < b. This will be done by using integration to find the area under the curve or volume of revolution about an axis. The two areas that will be compared will be labeled ‘A’ and ‘B’ (see figure A). In order to prove or disprove my conjectures‚ several different values for n will

Investigating the Biomolecules found in Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein)

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products
