Explanation:
Question 1:
It is better to use data from three or more seismic stations to find the epicenter of an earthquake because the intersection of three or more points gives a more accurate location of the epicenter.
- The method used in locating the position of an earthquake is simply by triangulating three or more points.
- Since we know the time of arrival and speed of earthquake waves, we use the distance at suitable scale to draw a circle at the seismic stations.
- The point of intersection of the circle gives the location of the epicenter of the earthquake waves.
- Using 1 or 2 locations will not result in an accurate position determination.
- A single circle from a seismograph station would only give us the region where earthquake must have likely occurred.
- Two circles will narrow down the odds of determining the position.
- Three or more circles gives perfect intersection which shows the position of the epicenter of the earthquake.
Question 2:
Properties of P-waves
- P-waves are known as primary waves.
- The have a velocity of about 5-8km/s
- They are always the first wave to arrive at a seismic station.
- They are propagated longitudinally i.e parallel to their source.
- They can pass through any earth materials be it solid liquids or gases.
- P-waves are body waves that moves within a body
Properties of S-waves.
- They are also known as secondary or shear waves.
- Their velocity is about 1-8km/s
- They are the second to arrive at a seismic station.
- They are propagated transversely to their source.
- They cannot pass through liquids and gases because they cannot be sheared.
- S-waves are body waves.
Question 3:
The conclusion that can be drawn from this is that the waves only pass through a solid material.
- P-waves are elastic seismic waves that can pass through any materials.
- They are always the first to arrive at a seismic station.
S-waves are secondary waves that will only pass through solid because they can shear.
Liquids and gases do not shear and will not allow s-waves to pass through them.
Since no s-waves are seen or recorded on the seismograph, we can infer that the material through which the waves cuts through is a solid alone.

I’m pretty sure it’s a limiting factor. Yeah, it is.
<span>The body is constantly changing, no matter what age. It has to maintain homeostasis, or balance at all times or illness/death occurs. If your body is weakened, it then becomes harder to maintain this state. If one component goes out of balance; ie, water content, it affects the whole body. Swelling(edema) CHF(serious heart problem) kidneys may be overtaxed/unable to release the extra fluid. As the body ages organs naturally become less efficient, therefore making homeostasis more challenging.</span>
Answer:
a. Streptococcus aureus
Explanation:
Toxic shock-like syndrome
It is the condition which is caused due to bacterial toxins .
The symptoms of Toxic -like syndrome are , skin peeling , rashes , fever , low blood pressure ,
infections such as , pneumonia , osteomyelitis are also seen .
It is called by bacteria type , the Streptococcus pyogenes or Staphylococcus aureus .
Streptococcal toxic shock syndrome is also called as the toxic-shock-like syndrome (TSLS) .
