Correct Question:

Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X

A. has a lower amplitude.

B. has a shorter wavelength.

C. has a longer wavelength.

D. has a greater amplitude.

Answer:

C. has a longer wavelength.

The basic equation of frequency and speed are

velocity = frequency x wavelength

When both waves' velocities are the same then

v1 = v2

f-1 x wavelenght-1 = f-2 x wavelenght-2

Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.

Answer:

Genotype ratio = 1 X^hX : 1 XX : 1 X^hY : 1 XY

Phenotype ratio = 2 normal daughters : 1 affected son : 1 normal son

Explanation:

Given that the father of the woman has hemophilia, the father must have transferred the allele for hemophilia (let us assume "h") to her. This makes the woman carrier for the disease (genotype = X^hX). The genotype of the normal man would be "XY".

A cross between carrier woman and normal man would obtain 2 normal daughters, 1 affected son and 1 normal son.

Genotype ratio = 1 X^hX : 1 XX : 1 X^hY : 1 XY

Phenotype ratio = 2 normal daughters : 1 affected son : 1 normal son
