If there are multiple functional dependencies (fds) for the relation, then we have multiple choices for the order in which we apply the fds in the bcnf normalization procedure. Would those different orders (of applying fds) lead to different sets of new relations , yes.
What is normalization ?In a big database with just one relation, data duplication could happen. Repetition of the data may result in: Significantly expanding associations. Data maintenance and updating are challenging due to the need to look through several connected entries. Resources are wasted, and disc space is used inefficiently. Inconsistencies and errors are more likely to happen. The best way to overcome these challenges is to break down relations with redundant data into smaller, simpler, and well-structured relations that satisfy desirable qualities. The process of normalization involves breaking down the relationships into relationships with less traits.

how does agriculture contribute to water quality impairment (pollution)? in other words, how are sediment, nitrogen and phosphorus lost from agricultural activities?
When it rains or melts, the extra nitrogen and phosphorus in farm fields can wash into nearby waterways. Over time, the extra nitrogen and phosphorus can also seep through the soil and enter the groundwater. Water bodies may become eutrophicated due to high nitrogen and phosphorus levels.
What role does agriculture play in the contamination of water?
Surface water and groundwater both may suffer from agricultural pollutants. Runoff and infiltration move fertilizers and pesticides into nearby streams, rivers, and groundwater, meaning they don't stay stationary on the terrain where they are applied.
How does ag runoff impact the quality of the water?
By generating erosion, conveying fertilizers, pesticides, and heavy metals, as well as by reducing the amount of water that naturally flows in streams and rivers, excessive irrigation can have a negative impact on water quality. Selenium, a hazardous element that can damage waterfowl reproduction, can also accumulate as a result of it.

The best way to implement this communication is Shallow copy.
What is Shallow Copy?
A shallow copy of an object is a bitwise copy in which the values of the original object are copied into a new object that is formed. In circumstances where an object field refers to another object, only the reference address is replicated.
The references to objects' original memory addresses are stored in shallow copies.The original object's modifications to the new/copied item are reflected in the shallow copy.While pointing references to the objects, shallow copy stores a copy of the original item.Rapid copy is shallow copy.What is Deep Copy?
Deep copying is the term used to describe the repetitive copying process in which a duplicate of one object is consistently replicated in another. During this process, a brand-new collection of the object is first built, and copies of the offspring object then frequently replenish the ones found in the original collection.
Value copies of the object are kept in deep copies.Deep copies don't update the original item to reflect changes made to the new or duplicated object.Recursively copying the items while storing a duplicate of the original object is known as deep copy.Deep copy is slower than shallow copy.To know more about shallow copy and deep copy visit:

double salary;
// Function to calculate the salary based on the sales made
double calculateSalary(double sales)

// Local variable to hold the percentage of the sales
double percentage = 0.15;

In this program, the calculateSalary function takes in the sales made by the salesperson as an input and returns the salary to be paid based on 15% of the sales. The calculateSalary function has a local variable called percentage that holds the percentage of the sales to be used to calculate the salary.
The main function is used to input the sales made by the salesperson and call the calculateSalary function to calculate the salary. The salary variable used in the main function is the same global salary variable defined at the beginning of the program, which is used to store the calculated salary.
The comments in the program indicate which variables are local (e.g. percentage) and which are global (e.g. salary). This can help to clarify the scope and purpose of each variable used in the program.
