Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
<span>Biodiversity boosts ecosystem productivity where all species have an important role to play. plants, animals and microorganism provide services to which contribute to the delicately running natural cycle of life (biodiversity), that help make earth habitable and contribute to our way of living in more ways than one. From providing us meals and medicine (<span>apothecary)</span> they also help reduce the impact of natural disasters such as floods. Biodiversity helps to moderate the elements, reduces bills such as utility, and prevents any large scale damage. The organization Of Conservation American Forests says, "depending on location, species, size, and condition, shade from trees can reduce utility bills for air conditioning in residential and commercial buildings by 15 to 50 percent" </span>
