Eight of them. If the last xero was not significant it should not be there
Answer:
The correct answer is -
Numerator = 6
Denominator = 73
Explanation:
In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1
Numerator df = 7 - 1 = 6
Thus, the numerato would be - 6.
Denominator is calculated by subtracting the observation or variables from the total number of sample size.
Denominator df = 80- 7 = 73
In the broadest sense of the term, we have modified the genes of almost everything. We used selective breeding to breed the most resistant form of crops, the largest sized chickens, and others. In recent years we have even modified them through gene splicing and other methods. Nearly everything we eat, including including "organic" foods have been changed from their original DNA structure, in fact we do not even know anything's original genetic structure because of this. Genetic modification could also include mutations. Some crops have mutated due to pollution, disease, or other effects such as climate change. Without genetic modification our world would differ from what it looks like today.
Given what we know, we can confirm that cells tissues populations and ecosystems are all examples of components of the biosphere.
<h3>What is the biosphere?</h3>
- This is considered the highest level of organization of life on earth.
- It is the sum of all of the ecosystems present on the planet.
- Every living thing, from cells to entire forests, are contents of the biosphere.
Therefore, given that the biosphere is the sum of all ecosystems on planet Earth and includes every living thing, we can confirm that cells and ecosystems are both prime examples of this.

The best way to increase validity of data in an experiment is by performing the experiment numerous times and obtaining measurements and data upon each run of the experiment.
