Which observation should the scientists see is most promising for developing a testable hypothesis that helps determine the connection between organisms farming and biodiversity
A. 12 different fish species were observed in a small pond on land located within an organization farm upon your a conventional farming only three species.
B. An enormous number of starlings were observed in an orchard adjacent to organic farmland. Thousands of starlings, were estimated to be observed.
C. Twenty-one different wildflower species were observed in a meadow on a land located within an organic farm
The observation that should be seen as most promising for developing a testable hypothesis that helps determine the connection between organisms farming and biodiversity is:
C. Twenty-one different wildflower species were observed in a meadow on a land located within an organic farm.
This observation suggests that the organic farming practices on the land may be supporting a greater diversity of plant species, which in turn could support a greater diversity of other organisms.
Y= x - 7
X= 4
Y=
-3

If the equation is given as y = x - 7, we can substitute the value of x into the equation to find the corresponding value of y.
Given x = 4:
y = 4 - 7 = -3
So, when x = 4, y = -3.
Similarly, if x = 3:
y = 3 - 7 = -4
So, when x = 3, y = -4.
And if x = -3:
y = -3 - 7 = -10
So, when x = -3, y = -10.
X + 5y = 28
2x + 3y = 21
Solve for x and y
X=8, y= 4
X=6, y=1
X=3, y=5
To solve the system of equations:
1) X + 5y = 28
2) 2x + 3y = 21
You can use either the substitution method or the elimination method. Let's use the elimination method.
Multiply equation 1 by 2, and equation 2 by -1 to eliminate x:
1) 2(x + 5y) = 2(28) => 2x + 10y = 56
2) -1(2x + 3y) = -1(21) => -2x - 3y = -21
Adding the two equations together eliminates x:
2x + 10y -2x - 3y = 56 - 21
7y = 35
y = 35/7
y = 5
Now substitute the value of y back into equation 1:
x + 5(5) = 28
x + 25 = 28
x = 28 - 25
x = 3
Therefore, the solution to the system of equations is x = 3 and y = 5.
C. Twenty-one different wildflower species were observed in a meadow on a land located within an organic farm.
This observation is the most promising for developing a testable hypothesis because it demonstrates a diverse range of plant species in an organic farm, which suggests a potential connection between organic farming practices and increased biodiversity. By comparing the species diversity in the meadow within an organic farm to other areas, it could be possible to determine if organic farming practices contribute to higher levels of biodiversity.
In order to develop a testable hypothesis that helps determine the connection between organisms farming and biodiversity, scientists should look for an observation that provides evidence of a significant difference in biodiversity between different farming practices.
Out of the given options, the most promising observation is Option A: "12 different fish species were observed in a small pond on land located within an organic farm, while only three species were observed in a conventional farming area." This observation suggests a higher level of biodiversity in the organic farm compared to the conventional farm.
To determine the connection between organisms farming and biodiversity, scientists can formulate a hypothesis based on this observation. For example, they could hypothesize that organic farming practices, such as the absence of pesticides or the promotion of natural habitats, have a positive impact on the diversity of fish species in ponds. They can then design experiments or conduct further observational studies to test this hypothesis.
