P Waves are compressional and the fastest moving seismic wave

S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side.

Answer:

Explanation:

P WAVES are also called Primary waves. The properties of a primary wave include:

• They are longitudinal and compressional waves by nature

• They travel much faster than other waves

• They travel through the earth to reach the seismograph stations first

• They can travel through any kind of material, including fluids

• They travel at the speed of sound, so they travel at the speed of sound

S WAVES are also called Secondary waves. The properties of a secondary wave include:

• They are transverse and shear waves in nature

• They arrive at the seismograph stations after the fast- movign P-waves

• They can travel onlt through solids

• They are slower than P-waves,a nd speeds are normally 65% of that of P-waves

A woman with normal blood clotting ability whose father was a hemophiliac and whose mother was normal with no family history of

Alborosie

Answer:

The answer is 25%.

Explanation:

Hemophilia is a recessive illness that is x-linked.

If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.

Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.

The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.

So the probability that their first child will be a son with hemophilia is 25%.

I hope this answer helps.
