Answer:
I think sentence 3 bc it doesn't really make any sense Ik it's explaining it but it doesnt connect with the whole story as much I think it has to have more details
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 CPU executes arithmetic and logic operations in the arithmetic and logic unit (ALU).
<h3>What is an ALU, or an arithmetic and logic unit?</h3>
- A combinational digital circuit known as an arithmetic logic unit computes arithmetic and bitwise operations on integer binary integers.
- A floating-point unit, on the other hand, works with floating-point numbers.
- The component of a central processing unit known as an arithmetic-logic unit performs arithmetic and logic operations on the operands in computer instruction words.
- An Arithmetic Logic Unit (ALU) is a component found within computers that can execute logical operations in addition to arithmetic operations, such as AND, OR, Ex-OR, invert, etc (e.g. Addition, Subtraction, etc.).
