Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

Radio Frequency (RF) transmission characteristics or Radio Frequency by definition is known as a frequency in the range within which radio waves may be transmitted‚ from about 3 kilohertz to about 300‚000 Gigahertz. RF is also the range of oscillation that ranges from 3 KHz to 300 GHz and work hand in hand with the frequency of the radio waves and the fluctuation currents that carry radio signals. Radio Frequency has different types of properties but ones that are most important are the radiation

I found the concept on frequency distribution using Google and the search words “frequency distribution” at http://www.mathsisfun.com/data/frequency-distribution.html This website is geared towards younger people and therefore breaks down frequency distribution into very basic terms: values and their frequency (how often each value occurs). The website uses the example of a child’s soccer team and how many goals they scored in recent games. For the assignment this week‚ I have chosen to use the

About 5g of product obtained in A is being dissolved in distilled water. 2. The solution is then being heated in steam bath until purple or pink solid is obtained. 3. Step 1 and 2 are repeated for three times to make sure the purple or pink solid is obtained. (C) The cis to trans isomerisation 1. A solution of (0.02M; 14mg in

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

energetically excited atom is not a continuous distribution of all possible wavelengths‚ but rather consists of a few wavelengths giving a series of discrete lines. Spectroscopy is the analysis of that emitted light and its dispersion into to it’s component wavelengths and colors. Niels Bohr explained the discrete spectrum of hydrogen by relating it to the electron. Normally the electron in the hydrogen atom is located in the first energy-level. When a hydrogen atom atoms gains energy‚ the electron

Materials/Methods For unit 7.3 the experiment needed 2 microfuge tubes one labeled "L" for lactose and the other labeled "M" for maltose. The experiment also called for a total of 3 clean plastic pipettes. With one pipette add milk up to the 0.5 line of the lactose tube. With the second clean pipette add maltose solution up to the 0.5

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build
