Describe how the three different types of seismic waves move and affect the movement of the material they pass over or through.
son4ous [18]
Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves.
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves.
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground.

These waves affect the movement of other materials when they are passing through the interior or surface of the earth.
P waves can move through the solid rocks and even liquids. S waves do not travel through the  liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.

Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patient
dedylja [7]
Duchenne muyscular dystrophy is caused by a mutation on the X chromosome, so a male gets it from his mother's X, if she is a carrier. The male child gets a Y and no X from his father, so the disease is always transmitted through the X from the mother. If a female gets Duchenne muscular dystrophy she has to have two X chromosomes, one from a carrier mother and another from from an affected father. This is virtually impossible because most males die before childbearing age and there is no way a female child can get an X from a man who does not live long enough to procreate. About eight percent of carrier women do show some muscle weakness, but they do not have the disease.
