Hydras or animals related to Coral and Jellyfish hydrous can reproduce sexually or asexually why would hydras avoid reproducing asexually when conditions are difficult reproducing more slowly would be a good way to take advantage of plentiful resources be reproducing more rapidly would be a good way to take advantage of plentiful resources see the lack of genetic diversity could mean that all the hydrants died depending on the situation D the high genetic diversity could mean that all the hydra's died depending on the situation

Hydras, along with other animals related to coral and jellyfish, have the ability to reproduce both sexually and asexually. The decision to choose a particular reproductive mode depends on various factors, including the availability of resources and the environmental conditions.

In situations where conditions are difficult and resources are scarce, reproducing more slowly and conservatively (sexually) can be advantageous for hydras. Sexual reproduction allows for the generation of offspring with increased genetic diversity, which can enhance their chances of survival in changing or challenging environments. This genetic diversity provides a wider range of traits and adaptations, ensuring that at least some individuals have characteristics suitable for the prevailing conditions.

Alternatively, when resources are abundant and conditions are favorable, hydras may choose to reproduce more rapidly and asexually. Asexual reproduction allows for the quick production of genetically identical offspring, which can take advantage of the plentiful resources. This fast reproduction can result in a larger population size, increasing their overall chances of survival and occupying available resources efficiently.

It is important to note that the lack or high genetic diversity does not necessarily determine the survival or extinction of a species. Genetic diversity is generally beneficial for a population's long-term survival as it increases the likelihood of at least some individuals possessing advantageous traits. However, the outcome will ultimately depend on the specific situation, such as the type and magnitude of environmental changes or the presence of any new threats.
