Answer:
Best example would be Carnot engine. It is possible in theory not in real life.
Explanation:
In real engines, the heat transfers at a sudden change in temperature whereas in a Carnot engine, the temperature remains constant. In our day to day lives, reversible processes can't be carried out and there is no such engine with 100 % efficiency. Thus, the Carnot cycle is practically not possible.
C. Convergent
Explanation:
When two plate boundaries collide, it causes earthquakes. The deepest and most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
Answer:
Following are the result for deforestation in the Amazon rain forest :
1. Environmental imbalance - Due to deforestation the amount of green houses gases will increase that cause the global warming of the environment.
2. Desertification - The most of area become dry and after that these areas will become desert .This will become unsuitable for any type of organism.
3. Flooding -The chances of over flowing water will increase.
4 . Soil erosion :The soil will become infertile.That is why lots of problem will generate.
5.Climate change - As we know that trees are very essential for our life.But due to deforestation the number of tress are decreases every day that cause the lot of climate change condition like high temperature,too much cold.
Plants have these because root nodules<span> are formed when nitrogen fixing bacteria called "rhizobia" start to enter the cells of a host </span>plant<span>. Rhizobia normally live inside of the soil and they </span>can<span> exist without a host </span>plant<span>.</span>
