The role of the retina is to receive light that the lens has focused. It then converts the light into neural signals which get sent to the brain for visual recognition.
My best guest is probably C or A.
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.
Answer:
Convection currents are what cause the warmer molten material to rise up, and when it cools, to sink back down.
Explanation:
