a unicellular, prokaryotic organism is discovered by scientists are these characteristics enough to place it in a domain, or is
more information needed?

a. more information is needed because it could be a member of bacteria or archaea.

b. more information is needed because it could be a member of eukarya or archaea.

c. these characteristics are enough because it can be determined to be a member of bacteria.

d. these characteristics are enough because it can be determined to be a member of eukarya.

Hello!

The correct answer is A, more information is needed, because organisms from both the bacteria and archaea domains are prokaryotic and unicellular.

I hope I helped!

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
