Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. I hope this helps
Not much information ab the question ?
Answer:
Option). They have a double-bonded oxygen in different locations.
Explanation:
Both glucose and fructose are monosaccharides, having molecular formula C₆H₁₂O₆.
Glucose and fructose are different sugars, aldose and ketose respectively, due to the different position of carbonyl group (double bonded oxygen with carbon or C = O group).
In glucose, the oxygen atom makes double bonds with last carbon atom of the chain, which means carbonyl group shows an aldehyde group. Thus, it is an aldose sugar.
In fructose, the oxygen makes double bonds with an internal carbon atom and represents a ketone group. Thus, it is a ketose sugar.
Thus, the correct answer is third option.
Answer:
D) pollination failure
Explanation:
Pollination failure can be caused by several factors which limit the chances of pollen being transferred to the stigmas, and/or prevents forming of fruits. In the nut trees, as a result of the self-incompatible flowers which limit the number of pollinators to only orchid bees, pollination failure is the most likely source of the problem why fruits don’t set. The selective nature of the nut flowers reduces the numbers of pollinators.
