Read the two experiments below.

experiment 1: a group of students tested to see if the acidity of water affected pea plant growth. the students followed a logical method and performed their experiment once, using control and experimental groups. their results supported their hypothesis.

experiment 2: a group of students tested to see if bacteria growth in water was affected by acidity. the students used control and experimental groups. they repeated their experiment several times and found the results were the same.
which experiment most likely has greater reliability?

a. number 1 because it follows a logical method
b. number 2 because the experiment was repeated
c. number 2 because the experiment was repeated and the results
were always the same
d. number 1 because it has control groups

Number 1, because the experiment was created with the same results

The correct answer would be C.Number 2 because the experiment was repeated and the results were always the same.

Reliability refers to the degree of consistency and stability of any tool, test, or any experiment.

The test, tools, or experiments which produce the same results every time it is used.

In experiment 2, the same experiment was performed multiple times and every time the results produced were the same.  

Thus, experiment 2 is more reliable.

explanation:

b,bacteria convert nitrates

into nitrogen gas.

d,plants and animals take in

and use nitrogen compounds.

e,bacteria break down waste    

products and return nitrogen  

to the soil.

a,bacteria convert atmospheric

nitrogen to ammonia.

c,bacteria convert ammonia

to nitrites and nitrates.
