Carbondioxide, being a green house gas has the property of trapping the heat from the sunlight and thus increasing the temperature of the place. As more and more rain forests are cut down and burned, there is an increase in this green house gas in the atmosphere thus leading to a steady increase in the temperatures.
As we look at the graphs that are given, we can see that the graph C shows the steady increase in the temperature as the time passes. Hence option C is the right answer
The two cycles are photosynthesis and cellular respiration.
Cellular respiration releases energy stored in glucose (during photosynthesis). Most of this energy is transferred to an energy molecule that can be used by all cells: ATP.
And the wastes of respiration that are carbon dioxide and water, which are precisely the raw materials of photosynthesis in chloroplasts (forming two linked closed cycle).
Answer:
The unsaturated fatty acid contains two less hydrogen atoms. Saturated fats are solid fats, like the animal fats lard and butter, whereas unsaturated fats are more fluid and form oils, such as vegetable oil. ... Unsaturated fatty oils can be transformed into a trans fat by adding hydrogen atoms.
