What are the characteristics of archaebacteria

Archaebacteria are primitive bacteria that have a cell wall with branched lipids that helps them tolerate adverse conditions.

hope this helps!

((:

Single celled prokaryotes,  no nucleus, free floating genetic material

Explanation:

The characteristics of archaebacteria include the following -

1. All the archaebacteria are unicellular organism, which are the oldest prokaryotes found on earth.

2. They are capable to survive in extreme weather conditions such as volcanoes

3. Their cell wall is made up of lipids with linkages of "ether"

4. They are devoid of nucleus, Golgi complexes, lysosomes, ER, mitochondria.

5. Cell organelles are not membrane bound and thus genetic material floats freely.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
