Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
Explanation:
Answer:
B - between 100 and 500 million year old.
Explanation:
Because X is older than the 100 layer but younger than the 500 layer according to the position in the picture.
Cladograms is a branching which bears a lot in common with the idea of family trees. In a cladogram what occurs at a node is a "splitting event". <span>At each </span>node<span> a splitting event </span>occurs which represents the cumulative change that happens in population over time.
C. The scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required"
<h3>What is pixel resolution?</h3>
Pixels per inch and pixels per centimeter are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner.
A 7 Tesla scanner, or 7T scanner is preferable to a 3T scanner because the 7 Tesla scanner gives higher pixel resolution when compared to 3 Tesla scanner.
Thus, the scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required".

D is the correct answer. -<span> A dense network of capillaries surrounds them.</span>
Capillaries are very small about 1 cell thick which makes them more suitable to exchanging gases rather than a vein or an artery.Capillaries allow the exchange of gases, nutrients and fluids by the process of diffusion between the body and the body tissues.
