Question

In the three domain system, which of the following domains includes organisms from more than one kingdom?



Bacteria



Eukarya



Archaea

Answer 1

@HisOnlyForever Think of some examples for each Domain. I'll bet you that will help.

Answer 2

I dunno lol .

Answer 3

@HisOnlyForever What Domain would you say humans are in?

Answer 4

I don't even know what the 2nd or 3rd ones mean ?

Answer 5

@HisOnlyForever Archaea is a group of single cell organisms formally treated as bacteria that are frequently called "extremeophiles". You find Archaeae in salt crystals, deep ocean heat vents, extremely acidic water, etc. Eukarya is organisms with organelles with plasma membranes like the nucleus, mitochondria, and chloroplast.

Answer 6

So humans are in bacteria ?

Answer 7

@HisOnlyForever No, bacteria are also single cell organsism that have a single circular chromosome and do not have their DNA in a nucleus and lack all membrane bound organelles.

The current members of Archaea were in Bacteria at one point, but now we know they are significantly different.

Answer 8

Um , so theyre in archaea ?

Answer 9

Still need help? @HisOnlyForever

Answer 10

Yea , whats the answer . lol he never told me .

Answer 11

@HisOnlyForever No, Archeae and Bacteria are two separate domains that both contain only single cell organisms that lack membrane bound organelles. I don't know how much more clearly I can explain it.

Eukarya is the domain with Kingdoms. This domain contains plants, fungi, animals, protists. There can be single cell organisms or multicellular organisms, but all have membrane bound organelles.

Thank you !
