An error is a misconception that can happen when doing some work that is not concluded accordingly. Some of the errors that concern are gross, random, systematic, and computer errors.
<h3>What are the types of errors?</h3>
Gross error is an error that is unpredictable and is due to s a sudden change because of the operator or the system. While random errors are caused to mistake in observed values.
Systematic errors are the identifiable errors that change the results of the experiment and a computer error is a mistake made by the computer system.
Therefore, random, systematic, computer and gross are the types of errors.

Answer:
2 OR4 ; both correct
Explanation:
x^2=7
x^4+y^2=50
x^4=(x^2)^2=(7)^2=49 --> 49+y^2=50
y^2=50-49=1 --> y=±
--> y=±1
+1 or -1 both possible --> solve both
+1+w=3 --> w = 3 - 1 = 2
OR
-1+w=3 --> w = 3 + 1 = 4
The correct answer is - B) the water quality of the stream.
By studying the fish populations and their well being, the watersheds, as well as the composition of the water, the scientists are trying to keep track of the situation of the quality of the water in the stream.
The fish populations, their activity, well being, are always a nice indicator about the water quality, as they live in it and are directly effected by any negative changes in the water quality.
The watersheds can also show a partial picture of the quality of the water in the streams, and that is because the water passes through them before entering the stream itself, so a clean and healthy watershed, often means good quality of the water.
The most relevant indicator of the quality of the water in the stream is still the testing of the water itself, where the water composition can be examined in detail thus to be determined its condition.
