The conservation of tillage practices leads to agricultural sustainability by protecting the farmer's crops from insects and other pests, thus, it reduces the need for the farmers to buy pesticides for the crops, since the tillage method prevents insects.
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
Answer:
Starch + H2O = maltose
This reaction gives the Starch and H2O as the reactants and Maltose as the product.
Amylase is an enzyme which helps in the digestion of Starch molecules and its activity can however be measured through careful monitoring of the disappearance of amylase substrate which is in this case, starch.
