The function of a specific enzyme is most directly influenced by its Chemicals that help chemical reactions occur at faster rates in living organisms are known as

the cell theory states that all living things including animals, as well as plants, are made of cells.

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.
