Answer:
B) Developer is poured down the drain while fixer can be reduced
Explanation:
The effluents produced during photographic processing includes, wash water, bleach, fixer, and developer
The developer is an alkaline solution, with a pH of approximately 10.0, while the pH of the fixer is about 4.3, it is therefore, acidic
The rate of discharge of the developer to the fixer is 2 to 1, and the exhausted developer, fixer and process effluents combined are neutral and can be handle by the the treatment works and the drain pipes
Fixer which remain clear can be reused for more than a day, while the spent basic Developer and the acidic Spent Stop Bath can be combined to form a neutral solution, having a pH of approximately 7, which make them less hazardous to be disposed off down the sink into the drain
Therefore, <em>developer is poured down the drain while fixer can be reused</em>
<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>
Explanation:
Since the program is not given, I will try to guide you about the mode of parameters.
The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).
While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.
If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.
Disk encryption is highly risky response.
<u>Explanation:</u>
To protect or loss of serial data loss on mobile devices it is not advisable to implement full disk encrypted. Once full disk encrypted is implemented mobile access is very slow. End-user will complain to IT administrator.
Best solution either removes unwanted or unauthorized application from mobile to protect the data loss. Install antivirus program in each mobile.
Access or permission to application is removed so that mobile data loss can be avoided. End user should also be advised not to click on any link which they receive through SMS messages or other through any applications.
