¿Pueden dos terremotos de igual magnitud provocar daños muy diferentes? ¿Cómo?

nignag [31]

Answer:

Un terremoto con la misma magnitud y profundidad podría causar daños drásticamente diferentes dependiendo de la vulnerabilidad de la exposición. Por ejemplo, un terremoto M6 en California o Japón podría causar muy poco daño debido a las estrictas disposiciones sísmicas de los códigos de construcción. Mientras se encuentre en un país del tercer mundo, el daño podría ser catastrófico y se podrían perder millones de vidas.

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

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential 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. Response to Selection 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. Heritability 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.

The answer is Mullerian mimicry.

Mullerian mimicry is a kind of mimicry in which two or more poisonous animals generate identical presences as a shared protective tool. The theory behind this is that if a predator learns to avoid one of the poisonous species, it will also avoid the mimic species as well.

It is a natural process in which two or more often repugnant species, which may or may not be closely associated and share one or more common predators, have started to mimic each other's cautionary signals, for their communal benefit, as predators eventually learn to avoid all of them.
