A simple microscope consists of 3 or 4 lenses with different magnifications
The range of ratio which can be used to indicate that a gene was not expressed in the cancerous tissue but was expressed in the healthy tissue is 0.5 - 0.0625.
Microarray is a technique that is used to measure the differences between the cancer cells and the normal cells. The method measures the amount of mRNA for genes that are present in a sample and compare the results between healthy and cancerous cells. A value of less than 1 indicates that the genes from the microarray are more active in normal cells.
Answer:
The answer is A.) Active Transport! :)
Normally, oxygen from the blood cells supply your muscles with the energy it needs to carry out certain actions. However, when there isn't enough oxygen to support the muscles, it produces lactic acid, or fermentation, to make up for the oxygen. (That's why you get that burn-y feeling whenever you exercise!)
