For each of the following groups (clades), indicate its sister group: a) Eukaryotes b) Opisthokonts c) Stramenopiles d) Protists e) Bacteria f) Bikonts

The sister group for the following are:

a) Eukaryotes

b) Opisthokonts

Sister group is Amoebazoans

c) Stramenopiles

Sister group is Alveolates

d) Protists

They don't have a sister group

e) Bacteria

Explanation:

Sister group is a term used in phylogeny to show the relationship between a group of organisms.

When two species come from a particular group or taxon, they are sister groups to each other.

Protists in the above answer does not have a sister group because most protists are not related to each other. Protists tend to be more related to plants or animals.
