Pedigree charts use shaded symbols to show organisms that have a particular trait, such as a defective gene, being traced in the

chart. A breeder wants to make a pedigree chart of male horses to avoid breeding males that have a defective gene. What symbol would the horse breeder use to show a male who is affected by a defective gene?

Males are represented my a square
if he is affected by a defective gene he should show a shaded square that differs from normal males just like this■

Answer:  A male who is affected by a defective gene would have a symbol of shaded square that the horse breeder would use in the pedigree that is ■.

Pedigree can be described as a representation of a family and its lineage ( that is its ancestory and line of descent) in a form of flow chart ( using standard symbols), which depicts the pattern of inheritance of a particular disease.

For a male, a symbol of square is used and for a female, a symbol of square is used  ( that are shaded if the individuals are affected with a disease)

Why are fixed resistors’ values indicated by color bands rather than printing the numeric value on their exterior?
gladu [14]
Because there are so many different values of numbers, it would be impractical to use 1Ω, 2Ω, 3Ω... etc... Using colored bands helps make reading it a little easier to the trained eye. There are hundreds of thousands, if not tens of millions of different resistors would need to exist to cover every value. So you just use something called "preferred values" with their resistance values posted on them instead.

Gre4nikov [31]

Answer : The equilibrium concentration of NO is, 0.0092 M.

Solution :

First we have to calculate the concentration of NO.

\text{Concentration of NO}=\frac{\text{Moles of }NO}{\text{Volume of solution}}=\frac{0.3152mol}{2.0L}=0.1576M

The given equilibrium reaction is,

                           N_2(g)+O_2(g)\rightleftharpoons 2NO(g)

Initially conc.      0        0           0.1576

At eqm.               (x)       (x)        (0.1576-2x)

The expression of K_c will be,

K_c=\frac{[NO]^2}{[N_2][O_2]}

0.0153=\frac{(0.1576-2x)^2}{(x)\times (x)}

By solving the term, we get:

x=0.0742,0.0839

Neglecting the 0.0839 value of x because it can not be more than initial value.

Thus, the value of 'x' will be, 0.0742 M

Now we have to calculate the equilibrium concentration of NO.

Equilibrium concentration of NO = (0.1576-2x) = [0.1576-2(0.0742)] = 0.0092 M

Therefore, the equilibrium concentration of NO is, 0.0092 M.
