What was the experimental method used to determine the GFP three-dimensional structure?
The three-dimensional structure of green fluorescent protein (GFP) was determined using X-ray crystallography. Researchers crystallized GFP and then diffracted X-rays through the crystal to collect data on how the X-rays scattered. By analyzing the resulting diffraction patterns, they could reconstruct the electron density map of the protein, ultimately allowing them to model the three-dimensional structure. This method provided detailed insights into GFP's unique chromophore and its fluorescent properties.

Is probable a synonym for analytic?
No. Probable means that a particular outcome is likely. Probability means the analytic likelihood of a particular outcome. Analysis (analytic, i.e. the method) means, for example, the evaluation of the outcomes to determine how well the experimental probability aligns with the theoretical probability.
What are the different ways in gathering data in statistics?
1. Direct Interview/Interviewing 2. Indirect/Questionnaire -->used in researching 3. Registration Method 4. Experimental Method
How do you determine the mass of an irregular shaped object using displacement method?
The displacement method is used to determine volume. However, if you know the density, the displacement test can give volume, which is used to work out mass by the formula m = dV
What is the process used by Archimedes to determine the volume of a sphere with equal weights?
THE Method of Equilibrium
What method is use for the equation one quarter of a number increase by 5 what is the number?
"one quarter of a number increased by 5" is an expression. It is NOT an equation. There is, therefore, no method that can be used to determine what the number is.
What experimental method has allowed scientists to estimate atomic and ionic radii?
X-ray crystallography is the experimental method used to determine atomic and ionic radii. By analyzing X-ray diffraction patterns from crystals, scientists can calculate the distances between atoms and derive their radii. This technique has been fundamental in understanding the structure of materials at the atomic level.
What experimental method can be used to determine the value of the rate constant in a chemical reaction?
The experimental method that can be used to determine the value of the rate constant in a chemical reaction is called the method of initial rates. This method involves conducting multiple experiments with varying initial concentrations of reactants and measuring the initial rate of the reaction. By analyzing the data obtained from these experiments, the rate constant can be calculated.
What experimental methods can be used to determine the specific rate constant, k, for a chemical reaction?
Experimental methods that can be used to determine the specific rate constant, k, for a chemical reaction include the method of initial rates, the method of integrated rate laws, and the method of isolation. These methods involve varying the concentrations of reactants, measuring the rate of reaction at different conditions, and analyzing the data to determine the rate constant.
What experimental method was used to measure the charge of an electron?
The experimental method used to measure the charge of an electron is called the Millikan oil drop experiment. In this experiment, tiny oil droplets were suspended in an electric field and their motion was observed to determine the charge of the electron.
What is a research method that allows you to determine cause and effect?
An experimental research method allows you to determine cause and effect by manipulating an independent variable to observe its effect on a dependent variable while controlling for potential confounding variables. Random assignment of participants to different conditions is a key feature of experimental designs.
We used a formal method of study with control and experimental groups to determine whether plants grew faster or slower when exposed to infrared light. what is the student describing?
Using the scientific method
What are the differences between the method of sections and the method of joints in structural analysis?
The method of sections involves cutting through a structure to analyze specific sections for forces and stresses, while the method of joints analyzes the forces at individual joints in a structure to determine overall stability and strength.
Which data collection method is not subject to non response bias?
experimental method
What analysis methods cannot be applied to experimental research?

What advantage does the experimental method have over non-experimental methods of research?
The experimental method allows researchers to establish cause-and-effect relationships by manipulating variables and controlling for confounding factors. This method provides more control over the research setting, increasing internal validity compared to non-experimental methods.
Scientists can determine the age of a substance using a method that compares the amounts of different forms of carbon atoms present in the substance Is this method more useful for organic substances?
