C. One organism benefits and the other is negatively affected.
The value of the given prefix expression *2 / 8 4 3 is calculated to be; 1
<h3>How to work with preorder transversals?</h3>
We are given the expression; *2 / 8 4 3
We will start from the rightmost operation symbol.
For every operation symbol, the two integers following the operation symbol are the symbols on which the operation needs to be performed. Then we replace the operation symbol with the two following integers by the result of the operation.
Then we repeat for the rightmost operation symbol in the remaining string.
*2 / 8 4 3
8 / 4 = 2
⇒ *2 2 3
2 * 2 = 4
4 - 3 = 1
Thus the value of the prefix expression is then 1.

Answer:
299m + 261j >= 1000
Explanation:
The inequality equation is basically the mg of per glass of milk times the m cups of milk + mg per glass of juice times the j glasses of juice should be greater than or equal to required 1,000 mg per day
The distance in miles from P to Q is 12 miles
<h3>Distances and speed</h3>
Let the distance from P to Q be "d"
Since the formula for calculating speed is expressed as:
For the distance of P to Q
40 = d/t
d = 40t
If he drives back at an average speed of 45mph and 2 mintes less, then;
45 = d/t - 0.033
d = 45 (t - 0.033)
Equating both distances
40t = 45(t - 0.033)
40t = 45t - 1.485
-5t = -1.485
t = 0.297
Get the distance from P to Q:
d = 40(0.297)
d = 11.88 miles
Hence the distance in miles from P to Q is 12 miles

Answer:
He could have shut off the power first and de-energize the circuits in order to prevent being electrocuted.
Explanation:
Electrical Safety is very important, <em>especially for those working in such hazardous situations. </em>Almost all our things in the society are electrically-operated, thus it even becomes relevant to have an idea on how we can prevent from obtaining an electrical shock or burns due to faulty electrical tools.
In the worker's scenario above, it is clear that he did not shut off the power at the circuit breaker panel. This is the most important thing that one must include in his plan when attempting to correct an electrical problem. You must find where the electrical switch, fuses and circuit breakers are at first. Once you find their location, you have to turn them off (even if the circuits are of low-voltage).<u> In order to make sure that they are really turned off, test the circuits first. This will help you ensure that they are, indeed, de-energized.</u>
