i think that is because 2 causes:
1- to know if red liquid is blood or not
2- to know type of animal as each animal has special crystal shape
A experiment done in a test tube is commonly referred to as an "in vitro" experiment. This type of experiment allows for controlled conditions within the test tube to study biological processes or reactions outside of a living organism.
the lab report is a record of all what was done in an experiment EXAMPLE : fromat 1) date: is when the experiment was done title of experiment :what is all about : 2) aim: what the experiment is hoping to achieve (HYPOTHESIS) ... 3 apparatus and material _ all that is needed to carry out the experiment... 4) proceduce method _step by step account of what was done. i,me ,you ,she,he are not used result ,data analyis , conclusion
A sequence of precisely stated steps that describe how an experiment is done using the appropriate materials is called a protocol. It outlines the procedures, materials, and techniques required to conduct the experiment in a reproducible manner. Following a protocol ensures consistency and accuracy in scientific research.
When you use the steps followed during an experiment, it is called the experimental procedure or the methodological approach. This includes the specific actions taken and the sequence in which they are carried out to conduct the experiment.
The variable that changes as a result of deliberate manipulation or intervention in an experiment is called the dependent variable. It is the variable that is observed and measured to determine the effect of the independent variable.
"for his researches into the constitution of haemin and chlorophyll and especially for his synthesis of haemin"
The reason for the experiment is to answer the problem
The Nobel Prize in Chemistry 1930 was awarded to Hans Fischer for his researches into the constitution of haemin and chlorophyll and especially for his synthesis of haemin.
Experiment done the most is doing hypothesis
on heating haemoglobin undergo denaturation and oxidized.the ferric ion rects with nippe's fluid, which containing 1% KCl,KBr,KI IN ACETIC ACID to form heamatin chloride or hemin.
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
a controlled experiment is an experiment that has an iv, dv, and a control, is in a well handled environment, and the experiment is safely done.
It is the "aim"
No
Haemin crystals are needle-like structures that form when hemoglobin is oxidized and turns into methemoglobin. These crystals are commonly seen in blood smears from patients with certain types of hemolytic anemias or hemoglobinopathies. They are visualized under a microscope and their presence can aid in diagnosing these conditions.
The data should be organized and the experiment's materials cleaned?
Davison and Germer used a nickel (Ni) crystal in their experiment to scatter electrons and observe their diffraction patterns. By bombarding the nickel crystal with electrons, they were able to demonstrate the wave-like behavior of electrons, confirming the wave-particle duality theory proposed by Louis de Broglie.
