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:
Bacteria provides vitamins to humans
Explanation:
The correct answer would be that bacteria provides vitamins to humans.
<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>
Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.
<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>
