Explain why Calix's cells having more DNA than a normal cat meant point mutation was not the cause.

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.

the answer is d p: cell, q: organ, r: organ system, s: tissue

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
