The oil extracted through these methods is referred to as "green crude" and it's not ready to be used as fuel until it undergoes another process called transesterification. This step adds more substances to the mix, including alcohol and a chemical catalyst that causes the alcohol to react with the oil. This reaction creates a mix of biodiesel and glycerol. The final step in processing separates the glycerol from the mixture and leaves a biodiesel that's ready to be used as fuel. Maybe one day it really will be easy being green.

The letter should contain concerns about the causes and ill effects of erosion.
<h3><u>Explanation</u>:</h3>
Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.
The plants having wide tips (trait A) retain the moisture, which means they are more prone to infection. So, the number of plants having trait A would be the most affected among all, and their number will significantly decrease, or may become extinct.
The plants having drip tips (trait B) drains away all the moisture, which means, they are less prone to fungal infections. So, the plants having drip tips would be the more abundant as compared to other traits.
The plant having mid-tip (trait C) retains a little amount of moisture. So, the plants having mid tip may or may not be infected, so, they can also survive, but the survival rate would be less than the drip-tip plants.
So, it can be concluded that plant having trait B would be most abundant in future, and plants having trait B would be less than plant having trait B, and the plant having trait A would either be extinct or least present.
Maybe c or d
