Answer:
9:3:3:1
Explanation:
There are 420 kernels, over half of these are purple wrinkled (242/420=0.576) one fifth are purple smooth (84/420=0.2), just under one fifth are yellow wrinkled (70/420=0.167), and just over one twentieth are yellow smooth (24/420 = 0.057).
The ratio is 0.567: 0.2: 0.167: 0.057
0.567/0.057 = 9.9, so the ratio of purple wrinkled to yellow smooth is around 9:1.
0.567/0.2 = 2.835 and 0.567/0.167 = 3.39, so the ratio of purple wrinkled to purple smooth and yellow wrinkled is approx 3:1
0.2/0.057 = 3.5 and 0.167/0.057 = 2.92, so the ratio of purple smooth and yellow wrinkled to yellow smooth is approx 3:1
Therefore, the ratio is approximately 9:3:3:1.
This is a classic Mendelian ratio for a independent assortment associated with a dihybrid cross.
You can approach this question by finding one answer that is wrong or by eliminating the answers that are correct.
Glycolysis is the breakdown of glucose into pyruvate. If you already know that glycolysis is oxygen-independent, meaning it does not require oxygen, then you immediately know that A is incorrect, making that the correct answer.
However, you can also go about it by eliminating B, C, and D. In glycolysis, glucose is breaking down with the help of ATP bringing in energy, so that means glucose, the simple sugar, is breaking down, so C is out. ATP is bringing that energy to the mitochondria, so B is out. And the energy from ATP is being consumed, so D is out.
