Phenylalanine has two known pKa charges: 1.83 and 9.13. To determine their individual ionic dissociation charges at pH 10, the equation to be used is
pH = pKa + log [α/(1-α)]
At pKa 1.83:
10 = 1.83 + log [α₁/(1-α₁)]
α₁ = 0.99999
At pKa 9.13:
10 = 9.13 + log [α₂/(1-α₂)]
α₂ = 0.88114
Average Net Charge = 0.99999 + 0.88114 = 1.88
Answer:
False
Explanation:
Gasses and have more space between molecules
Answer:
D.phototropism
Explanation:
Phototropism is a type of tropism in which a plant or plant part responds to light. According to this question, a student wanted to investigate the effect of light on the growth of cress seedlings. The student used three different pots for the experiment.
Pot 1 was placed with light from above. Pot 2 was placed in a cupboard with no light. Pot 3 was placed in a window with light from one direction only. However, the image attached to this question shows that the plants in the different pots face different directions in response to light, which depicts phototropism
