Describe two small scale events that an ecosystem may recover from what is meant by the term dynamic ecosystem

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 right answer is mentionned in the picture.

mitosis consists of dividing a mother cell into two daughter cells. unlike meiosis, mitosis is unsexed. there's four phases in mitosis: prophase, metaphase, anaphase and telophase (each phase is represented in the picture).

mitosis or cell division allows to multiply the number of cells while preserving the quantity and the quality of the information contained in the chromosomes. the course of mitosis depends on very precise mechanisms. these mechanisms are universal, that is to say common, with a few details, to all eukaryotic organisms, animals and plants.
