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>

The cell reference refers to a cell on a worksheet and can be used in a formula to point another location.
Explanation:
A cell reference is a range of cells on a worksheet that can be used in a formula to find the values or data you want to calculate using that formula.
There are two types of cell references relative and absolute. they both behave differently when copied to other cells. Relative references change when a formula is copied to another cell.
Absolute reference remains constant even if they are copied. In a formula multiplications are performed before subtraction.
It does not change when the formula is copied or moved to another cell.
Answer:
HVAC is stand for the heating, ventilation and the air conditioning system that basically perform various type computer management and operation system. It also helps to improve the productivity of the system.
As, HVAC system is very concerned about the security as it basically include various types of toxic chemical in the environment that include various types of criminal and terrorist activities and natural disaster.
The HVAC systems are easily cause various accidental cases due to its complexity nature. It also performing various types of function in the management sector like maintenance, system updating function an remote controlling maintenance.
