Endangered species with very small populations are especially at risk of loss of genetic diversity due to option(d) i.e, genetic drift.
A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species. Invasive species, habitat degradation, poaching, and other issues may put endangered animals in danger.
Genetic drift is the arbitrary change in the frequency of a gene variant in a population. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it has the potential to make previously uncommon alleles far more common and even fixed. Drift lowers genetic diversity in populations, which may limit a population's capacity to adapt to new selective pressures. In smaller populations, genetic drift is more pronounced and has more severe consequences. Particularly in the case of rare and endangered species, this effect is significant.
The complete question is:
Endangered species with very small populations are especially at risk of loss of genetic diversity due to:
immigration.
mutation.
natural selection.
genetic drift.

Answer;
-Organelles must work together and their
activities must be coordinated
Explanation;
Eukaryotic cells contains membrane bound organelles unlike proteins which are specialized to specific functions inside the cells. Such organelles include; mitochondria, lysosomes, golgi apparatus, etc.
These organelles are bound inside cell to make it more efficient for the cell to carry all its functions with each organelle specializing in z specific function.
All the organelles work together and their activities must be coordinated to enhance smooth running of activities inside a cell.
