Answer:
It can be characterized by the extreme heat or too much rainfall. Deforestation also degrades soil quality and is a major cause of the world's rapid desertification. Such weather patterns and environmental changes contribute to the plummeting of the agricultural production.

Your metabolism is in charge of converting food to energy
Explanation:
Answer:
At low Ts= Hopanoids increase membrane fluidity
At higher Ts= Hopanoids reduce the membrane fluidity
Explanation:
Bacterial membranes lack cholesterol but have hopanoids. Hopanoids are synthesized from the same precursor as the steroid. The hopanoids also have five fused ring structures like that of cholesterol. The amphipathic nature of hopanoids allows them to maintain the membrane fluidity under low and higher temperature conditions.
When the temperatures are higher, the hopanoids serve to reduce the membrane fluidity by their ability to interact with polar heads and non-polar tails of the membrane phospholipids. At lower temperatures, hopanoids insert themselves between the non-polar tails of phospholipids to increase the membrane fluidity.
