Question

large inclusive group in classification, group of related phyla *
domain
kingdom
class
family
group of closely related families *
class
phylum
genus
order
kingdom of unicellular prokaryotes whose cell walls do not contain peptidoglycan; survive in extremely harsh conditions
archeabacteria
eubacteria
protista
fungi

Explanation:

• First Question: In biological classification, a kingdom is a large inclusive group that can consist of related phyla. Domains are even larger but the description here fits kingdom better. Class and family are smaller groups.
• Second Question: In biological classification hierarchy, an order is a group of closely - related families. Class is a higher - level group (contains orders), phylum is a very high - level group (contains classes), and genus is a lower - level group (contains species).
• Third Question: Archeabacteria (Archaea) are unicellular prokaryotes. Their cell walls lack peptidoglycan (unlike Eubacteria) and they can survive in harsh conditions. Protista are eukaryotes (mostly unicellular), and Fungi are eukaryotes (with cell walls made of chitin in most cases).

Answer:

1. Kingdom
2. order
3. Archeabacteria
