Answer:

As a negative guide, to demonstrate that perhaps the injection itself has no impact on the cell cycle.

A successful experiment has handled the same control group as the experimental group with the exception of the variable being examined, in this case the cytoplasm M-phase.

B. Eggs are known to contain cholesterol, which is a lipid. Did your experiment results indicate a presence of lipids in the alb
Darya [45]

Answer:

According to the result recorded, there was no cholesterol in the albumin solution. This is probably because the cholesterol is in the egg yolk and not the egg white. In order to get a positive response on the presence of cholesterol in eggs, an egg yolk albumin stock needs to be prepared. So using the same procedure as before and only replacing the egg yolk for the egg white, prepare a 0.5 mL of egg yolk with 4.5 mL distilled water mixture in a test tube. Follow the steps given in the lab manual to check for presence of lipids in this albumin stock. Take a filter paper and add one drop of Sudan III solution onto it, let it dry and then place a drop of the stock prepared and analyze if the color transfer happens.

OverLord2011 [107]
The statement is true. There are two main anabolic stimuli for muscle that is exercise and protein ingestion. Protein not only provides the building blocks for the muscle, but also provides the trigger to stimulate muscle protein synthesis. Muscle protein synthesis is the physiological process of adding new amino acids to muscle  proteins and is the primary mechanism of muscle growth.
