Answer:
In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis.
Explanation:
If a p53 gene is defective it may cause cell cycle to stop functioning normally. Without this cell cycle check, cells will divide continuosly creating many chromosomal damage.
The correct answers are 2. arid climate and 4. oil resources
The climate always causes environmental climate, especially arid one, while oil both extraction and production creates environmental problems.
More fluid bilayers will be formed when the saturation of the fatty acids chains on a phospholipid is decreased.
Fatty acids are present in animals, plants and other microorganisms. They are composed of the carbon chain with carboxyl group at the end of the chain. The fatty acids are the vital components of the lipids, which are the essential fat soluble components. When the saturation level of these acids is decreased, it leads to the formation of more lipid bilayers.
Hence, the correct answer is 'more fluid bilayers'.
