You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s
inn [45]

Answer: 1. S = 0.77

              2. R = 0.14

Explanation:

1. <u><em>Selection</em></u> <u><em>differential</em></u> is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. <em><u>Heritability</u></em> is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

h^{2}=\frac{R}{S}

h^{2}=\frac{0.14}{0.77}

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.

CAM photosynthesis limits CO2 fixation to nighttime hours in order to (A) allow water to enter leaf spaces during the daylight h
bixtya [17]

Answer:

(B) open stomata only at night, limiting water loss because of heat and low humidity.

Explanation:

CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.  

They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.  

During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.

allochka39001 [22]

Sodium and potassium have opposite effects on heart health: High salt intake increases blood pressure, which can lead to heart disease, while high potassium intake can help relax blood vessels and excrete the sodium and decrease blood pressure.
