Most living cells contain catalase because many cellular reactions form hydrogen peroxide as a product. Mammalian liver has a high concentration which is the source of the catalase utilized in this experiment. The catalase decomposes the hydrogen peroxide .
The chromosomes settle midway between the two ends of the cell with their centromeres at the metaphase plate, which is an imaginary plane in the middle of the cell. Suppose you observed 32 whitefish blastula cells. One cell was in metaphase, 3 were in anaphase, 8 were in prophase, and 4 were in telophase.
The function of cellular respiration is to process the breaking down of chemical bonds of organic compounds such as those found in food, creating simpler molecules and storing the chemical energy that is released in molecules of adenosine triphosphate (ATP)The equation for cellular respiration is 6H12O6 + 6O2 → 6CO2 + 6H2O+energy.
Explain the two steps in polymerase chain reaction. Denaturation occurs when the two DNA strands separate due to high temperature exposure. Annealing occurs when short, specific DNA pieces attach at the starting point for DNA synthesis. Elongation (extension) is the building of a new DNA strand.
The mouse was the animal used for the experiment conducted by Joseph Priestly. Because oxygen was discovered when the experiment with mice in a jar was performed. A student replicates all the variables of the first experiment, except she puts the plant in a sealed jar without oxygen but with carbon dioxide.
