Answer:
The statement D 'they are assisted by vitamins and minerals' is incorrect.
Explanation:
Enzymes are biological catalysts which speed up a reaction. Their working mechanism is usually referred to as lock and key mechanisms as they make a lock and key type model while functioning. Each enzyme is specific for a specific kind of substrate. All enzymes are proteins. Enzymes itself are not degraded or get used up in a reaction. They might change from one form to another. But they are not assisted by vitamins or minerals, hence that statement is incorrect.

The methods that stimulate artificial erosion may cause numerous negative problems like climate change, deterioration of the quality of the soil, soil infertility, etc.
Erosion may be characterized as a type of geological process through which soil and its components are worn away and transported by natural forces such as wind or water. In a more simple sense, erosion is the migration of pieces of the earth's surface from one place to another by various means.
Erosion whether it is artificial or natural causes various negative impacts on the earth's surface. Artificial erosion is caused by the construction of roads, urbanization, deforestation, etc. All these factors ruin the entire biodiversity present on the earth. Finally, makes an environment unbalanced with respect to the resources available.
Therefore, the methods that stimulate artificial erosion may cause numerous negative problems like climate change, deterioration of the quality of the soil, soil infertility, etc.
