Dna is very unstable.

true
false

true Lindahl showed that DNA is inherently unstable and requires active repair, and established the role of DNA glycosylase enzymes in base excision repair.

a. the production of carbon dioxide through the process of photosynthesis

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.
