C.) Heat Convection within the earth.
Answer:
Archaebacteria
Explanation:
Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.
These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.
The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes. The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.
Thus, Archaebacteria is the correct answer.
D) THICK WAXY CUTICLE
The leaf have adaptations in order to do gas exchange, which are the follwings:
-Large surface area of mesophyll cells
-Interconnecting air spaces in mesophyll
-Many Stomata
A thick waxy cuticle is NOT an adaptation because the waxy cuticle is not thick, is thin, in order to have a short distance for the carbon dioxide to diffuse into the cells.
