suppose a new species of thermophilic bacteria is discovered that can live in undersea volcanic vents. researchers perform a microarray in order to determine the genetic similarities and differences between sulfur and high temperature tolerance. the results below show high gene expression in the experimental condition compared to the control as pink, low gene expression compared to the control as cyan, and no change in gene expression compared to the control as white. each letter represents a different gene. for the high temperature samples compared to the control gene a dark cyan gene b dark pink gene c dark pink gene d light cyan gene e dark cyan gene f light pink gene g light cyan gene h medium pink gene i medium cyan gene j light cyan gene k dark cyan. for the high sulfur samples compared to the control gene a dark cyan gene b medium cyan gene c medium pink gene d light cyan gene e dark cyan gene f light pink gene g light cyan gene h light cyan gene i medium cyan gene j dark pink gene k dark pink. what steps could the researchers do next in order to better understand the genes they identified?
