Because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph through th

Answer:

True.

Explanation:

Lymphatic system is one of the most important system of the body that carries the lymph fluid towards the heart. This system plays an important role in the body immune system.

The pressure in the lymph vessels are very low. The movement of adjacent tissue in the lymph is important to propel it through the lymphatics. The intrinsic or extrinsic compression are important for the lymph flow.

Thus, the correct answer is True.

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.

avanturin [10]

Answer:

Explanation:

We can easily move the box from a ground floor though to the first floor at an angle of 40° to the horizontal by simply pushing the load through an inclined plane. We will simply be lean the inclined plane on the building at the required angle and the push through the the height of the building.

Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>
