Soil pH affects nutrients available for plant growth. In highly acidic soil, aluminum and manganese can become more available and more toxic to plant while calcium, phosphorus, and magnesium are less available to the plant. In highly alkaline soil, phosphorus and most micronutrients become less available.
The answer your looking for is true I believe
Answer:
M.P = 140.46 Vm
Explanation:
Membrane potential can calculated using the following equation:
<em>(61/z) ln ([X]out/[X]in)</em>
where z is the charge of Ca2+ ion and X represent the concentrations By applying necessary calculations…
Membrane potential = (61 / 2) ln (100 x 10^-3 / 1 x 10^-3)
= 30.5 x 4.60 = 140.46 Vm
Two traits that we are examining are the color (purple/white) and the smoothness.
In our sample, we have 135 individuals ( 75 +28+24+8= 135).
Since we know that expected ratio of a dihybrid cross, is <span>9:3:3:1 we can calculate what is the expected values of each phenotype is.
So, for the white wrinkled phenotype, we expect that there will be one-sixteenth of the whole sample ( there are 16 parts of the whole sample 9+3+3+1=16).
So, we multiply the whole sample- 135 with one-sixteenth (or </span>0.0625) and get 8,4375.
When you calculate the values for all phenotypes you get results shown in the attached excel table.
When you have your expected and experimental values you compare them with a chi-square test. (The test determines if the difference between the expected and experimental results is statistically significant).
