The answer would be:
C: all cells are similar in structure and function
<em>Even though this answer is correct in content, this was not mentioned in the main idea of cell theory.

Biotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields.
Assuming a significance level of 0.05, X² < P₀.₀₅, so there is no enought evidence to reject the null hypothesis. We fail to reject it. She got the predicted ratios.
<h3><u>
Available data</u></h3>
- cross between two heter0zyg0us flies for eye color, Ww
- Observed numbers 210 white-eyed and 680 red-eyed flies.
The total number of individuals is 210 + 680 = 890
Let us first take the expected numbers from the expected ratio,
4 -------------890
3 ------------X = 667.5
1 -------------X = 222.5
<u>Red-eyed individuals White-eyed individuals</u>
Observed 680 210
Expected 667.5 222.5
(Obs-Exp)²/Exp 0.234 0.702
Now we need to get the chi-square value
X² = Σ(Obs-Exp)²/Exp
X² = 0.936
Degrees of freedom = n - 1 = 2 - 1 = 1
Significance level = 0.05
Critical value = 3.841
X² < P₀.₀₅
0.936 < 3.841
p value is greater than 0.05, so there is not enough evidence to reject the null hypothesis. The genotypes might be in equilibrium, and there might be independent assortment.
