Afew organisms have evolved to use mostly asexual reproduction. what must be true about these?

I cannot find the statements, I will explain the asexual reproduction so you can answer the question by your own:

Asexual reproduction is as simple a cell multiplication as a photocopying machine reproduced in one or more copies an original document.  In all cases, we obtain a clone of cells all having the same hereditary information.

The great advantage of asexual reproduction is its speed.
It produces a new organism that is genetically identical to the parent you do not have to look for a partner
Energy can be deployed to produce potentially large numbers of offspringOffspring are usually adapted to their environment by the success of their parent
Helps to quickly and effectively colonize a parent-friendly habitat, thanks to a large number of descendants he can breed in a short timeThe offspring are often already multicellular and more viable.

The inconveniences are:
Does not cause a genetic diversity of organisms of the same species.
The species does not adapt at all or very slowly depending on the changing circumstances.
There is only one parent to care for the offspring.
The parent disappears sometimes because his body is no more (binary fission, fragmentation).
An asexual species may be suddenly destroyed by a disaster that affects all genetically identical organisms of this species.
