Question

A pond contains many different types of organisms. The table below lists some of these organisms and their methods of reproduction
Organism
Pantala flavescens
Spirodela polyrhiza
Naegleria foweri
Hydra oligactis
Method of Reproduction
sperm and egg fusion
budding
binary fission
budding
Over time, the pond slowly becomes more acidic due to the release of chemicals from a nearby factory. Which of the organisms would most likely
survive the change to their environment?
A.
Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
B.
Hydra oligactis, because these organisms would have a low level of genetic variation due to sexual reproduction
c. Naegleria fowleri, because these organisms would have a high level of genetic variation due to asexual reproduction
D.
Spirodela polyrhiza, because these organisms would have a low level of genetic variation due to asexual reproduction

Answer 1

Answer:

Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction

Explanation:

Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment.  All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.

Hence, option A is correct.
