Due to global climate change, dumping of wastes and excessive pollution, a lake experiences abnormal changes in temperature and pH. The lake has species that reproduce exclusively through asexual methods while some can perform sexual reproduction.
Which of these species will most likely survive the rapidly changing conditions of the lake?

The correct option is B Sexually-reproducing species
Organisms that reproduce asexually produce offspring that genetically identical to their parents and the potential evolutionary advantage due to variations among offsprings are not there.
In the case of sexually reproducing organisms, they have a mix of maternal and paternal genetic material, which creates variation among the offsprings. The evolutionary advantage of variation due to a mix of genes, which may help them survive in a lake where temperature and pH are changing due to global climatic changes.
Generally, in lower organisms, asexual reproduction is preferred in favourable conditions while sexual reproduction is preferred in unfavourable conditions.
