Enzymes are not used in the reaction so usually the enzyme will sort of reset and be ready to use in another reaction . this is because enzymes are proteins and their shape is what they use in a chemical reaction so when the reaction is done the product is released (the reaction) and the enzyme can relax and go back to its normal shape
One of the main differences between butter and canola oil is that are room temperature one is a solid and the other is a liquid. This change in phase is due to the bonding between carbon bonds, the more double bonds that there are present the higher the melting point and the fluidity changes. Based on this the correct answer is C=C is found in canola oil while more C-C bonds are found in butter, making option 2 (C=C) the correct answer. In addition option 3 (C=H) can be ignored since hydrogen can only make single bonds. hope this helps:)
Consequently plant roots will get more moisture with less effort. It also improves soil structure due to alternate drying and cooling and soil aeration which helps in multiplication of micro-organisms. This is the reason that farmers plough their field during summer. These are reasons why farmers plough their fields during the summer.
Hope this helps! :3
