Biology Experiments Sex Protein Is as Essential

Biology Experiments

Sex protein is as essential part of the female reproductive system. Vitellogenin is a protein found in the liver of female chickens (hen) which impacts the production of estrogen. Vitellogenin enters the hen's circulatory system and is then moved to the ovaries, where it is then converted to the egg yolk protein lipovitellin and phosvitin. As an experimenter the protein in male and female chickens can be compared through the process of electrophoresis. This process will allow the experimenter to look at protein from these two specimens and identify the vitellogenin, lipovitellin and phosvitin. There are pre-stained cells that can be purchased and it only needs to be viewed under a microscope for observations.

Hypothesis: There is a difference between male and female chicken protein structure.

Experiment Two

Another research idea is to look at enzymes catalysis and determine which enzyme has a rapid time of completion. A rapid time of completion reflects how quickly the enzyme is performing its job. The time of completion is impacted by two factors the enzyme and the substrate used, therefore it is important to ensure you are using the same amount of substrate. Titration should be done using measurements of 5ml. Putting too much of the sample to titrate will cause permanganate and error. The experimenter would need the experiment would need "zero time" this will allow experimenter to calculate titration numbers and help them establish a baseline. If you can get purified crystal or dry yeast in warm water works great. You would need burettes for the titration process and droppers to measure the catalysis.

Experiment Three

Observing cell respiration is a way to learn more about plants. The first step involved with this process is getting all the equipment set up properly. It is imperative to understand that even with a small amount of time barometric pressure can change, rising and falling which impacts the quantification of oxygen gas O2 uptake. Since we know that the pressure changes, it is important to calculate for corrected differences to account for pressure changes. These barometric pressure changes must be accounted for during the preparation of the pea respiration data to ensure experiment is reliable.
