Answer:
Line graph
Explanation:
The most appropriate is a line graph because the experiment aims to show the changes of the plant over time. A line graph can express or show changes in values an in turn, it can show how one variable affects the other.
Attached is a rough example of a line graph of your data.
Hypothesis
Suppose we have four test tube each test tube is filled with solution extracted from different sources. Test tube 1 contain solution extracted from sugar cane, Test tube 2 contain solution extracted from green leaves, Test tube 3 contain solution extracted from seeds, and Test tube 4 contain egg white an albumin protein.
objectives
To find out which solution will react with biuret solution
.
Materials and method
To prepare biuret solution, mix potassium sodium tartarate with cupric sulfate and sodium hydroxide. A blue solution will be formed.
Experiment
Pour a small amount of biuret solution in each test tube and heat them until precipitation is formed.
Results
After analyzing the experiment, it was found that no color changed in first three test tubes except the fourth one in which the color was changed from blue to pink-purple.
Discussion
It was deduced from results that appearance of pink-purple color indicate the presence of peptide bonds (proteins)
Conclusion
Biuret test is used for the confirmation of proteins in any food sample.
Try to break it down into small parts and do your best to put it together.
Answer: False
Explanation:
The urethra is a tube which runs from the bladder to the end of the penis. It functions by carrying the urine and semen outside the male body.
Urethra is made of two components. Prostatic urethera is the part that runs from the bladder through the prostrate.
