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.
1 ) under water earthquakes cause a disturbance sending water outwards away from the point of the earthquake due to air and pressure coming into contact at gray force
Answer:
Generally the primary organic molecules in cells which support the metabolic and biochemical process of the cells are bio molecules Theses are Carbohydrate
Protein
Lipids
and Nucleic acids of DNA and RNA. They can also be the minute hormones and metabolites present in the cells.
Generally, CHO provide structural supports to the cells,and acts as sources of energy.
Protein forms most enzymes for biochemical reactions,and aids movements, through muscle contractions. Besides,muscles are made of protein.Therefore protein forms the structural basis of the muscles.This aids movement and locomotion for support.
Lipids are the richest source of energy for the cell,and provides support the cells membrane.
The nucleic acids,are primary concerned with the transfer of inheritable characteristic from mother cells to the daughters during reproduction.While the DNA is the genetic information been transferred,the RNA is the vehicle for transmission of the genetic information as protein from the parents' nucleus to the offspring. Thus the nucleic acid roles it for transmission of genetic information as genes,(DNA) and translation of these genes as proteins(RNA).Hence,Nucleic acids does not participate in the cells' support.
Therefore
Explanation:
Girls begin their growth spurt around age 10, while boys begin their growth spurt around age 12.
