if a cell developed a mutation in its mapk gene that prevented mapk from being recognized by phosphatases, how would the growth factor signaling cascade and the cell’s behavior change?

i don't know. if i were you, i would search it up online : d

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
