Abstract: This experiment will determine if jumping beans are alive. We tested two groups. Group A and B. We put them in two different areas. Three beans were put in a lit area and three were put in a shaded area. It was found that if the depending on how lit the area is the more movement we saw from the jumping bean. Therefore it can be said that jumping beans are alive and respond to stimuli. Introduction: This Experiment “ Mexican Jumping Beans” focuses on how jumping beans respond to different

There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many

white. It is because the protein in egg white undergoes denaturation‚ the cross linkage(the hydrogen bonds‚ ionic bonds and disulphride bonds) which maintain the protein shape destructed‚ so protein lose its tertiary conformation. This denaturing process is very important‚ because before protein can be used in digestion they must be unfolded. Part A: denaturation of egg white Aim: To examine the factors on the effect of denaturation of egg white. Principle: As protein denaturation can be cause

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

Describe two variables that affect the rate of diffusion. a. Two variables that affect the rate of diffusion are size and whether or not there is an electrical or concentration gradient. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction

A lab experiment is a method of research that enables the researcher to control the environment. It is a way of doing a research in a controlled environment on a certain behaviour which will have a cause and effect. It is done in a controlled environment so that extraneous variables are prevented from affecting the results. Behaviourists use lab experiments because they are interested in a cause and effect of certain behaviours. The aim is to control all relevant variables except for one key variable

EXERCISE 3: DIFFERENTIAL PROTEIN PRECIPITATION Vanessa Andrea Estepa University of Mindanao‚ College of Science and Mathematics ABSTRACT: Denaturation is the disruption in the original conformation of the protein wherein the secondary‚ tertiary and quaternary structures are all affected. Denaturation is brought about by various kinds of physical and chemical means; this includes the addition of strong acids‚ heavy metal cations‚ alkaloidal reagents‚ salting out and addition of organic solvents.
