Stomata- specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying when temperatures are hot and dry to prevent gas and water loss.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

this is math not biology xd

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.
