When the salt is dissolved in water The results is a?
Solution.
What is the condition in plant cells which results in a rigid form resulting from water absorption?
it is called endo-osmosis
Why do scientist insist that observations be made by at least two independent observers?
In order to minimize errors and confirm the results.
Why does the rate of evaporation of an aqueous solution decreases with increase in humidity?
As the humidity increases, the partial pressure of water vapor in the atmosphere (above the solution being evaporated) also increases. This results in more energy being necessary for the liquid water to evaporate, thus the higher the humidity, the longer it will take for evaporation of an aqueous solution to take place. This is essentially based on Dalton's Law of Partial Pressures.
What are the step in quantitative analysis?
Define problem, develop model, optain data, develop solution, solve equtions, test solution, analize results, implement results and change if necessary
How can people minimize the search results?
Go to the bed and sleep so it will minimize by itself and by eating kebe
What is a liquid dissolved in a gas results in a solution?
A gas results in a solution.
What stomach secretion is necessary for normal hemoglobin Production in RBC's?
Intrinsic factor is secreted by the parietal cells and is critical for absorption of B12. When the body attacks the parietal cells b12 deficiency results which is called "pernicious anemia."
What processes does chromatography go through?
preparation of the spotting solution and eluentpreparation of the mediumtransfer of the mixture to the mediumrunning the chromatogramif necessary, developing of the chromatogramanalysis of the results.
Absorption of what type of electromagnetic radiation results in electronic transitions?
Ultraviolet
Why is accreditation of veterinary labs necessary?
To ensure the quality of the results on labwork. Accredidation ensures that the testing equipment and materials is handled appropriately so as to be in good condition, that staff are trained and perform tests appropriately and that facilities are maintained in a way so as to minimize the risk of contamination of samples which could lead to false results.
When the salt is dissolved in water results in?
Solution.
What is the solution in the scientific process called?
Results

Solution.
Why is it necessary to test for complete precipitation if a supernatant solution is going to be subsequently tested for ions?
The presence of unprecipitated ions in the supernatant may react with subsequent reagents added and obscure the results of tests.
