Likurg_2 [28]

D. The waves encounter entirely different mediums.

<h3>Why does the amplitude of a seismic wave decrease as the wave moves away from the epicenter?</h3>

At farther distances, the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume and different mediums of Earth.

So we can conclude that option D is the right answer.

Alexxx [7]
1. The law of conservation of mass applies to this reaction because when you look at its balanced chemical equation, the same amount or ratio of elements can be found:

C + O2 --> CO2

This shows that the product will have the same ratio of reactants.

2. The original piece of wood and resulting ashes do not weight the same because the combustible parts of the wood were burned and converted to gases. This means that the missing mass is equal to the gases produced. The remaining ashes are the incombustible parts of the wood.

yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.
