Answer:
Petroleum gas is mainly C3 and C4 based (propane and butane), whilst natural gas is predominantly C1 and C2 (methane and ethane). Petroleum gas is generally produced via the cracking of naphtha, which is one of the components separated during crude oil refining.
Explanation:
Reactants are the molecules that begin cellular respiration, in this case that would be oxygen<span> and </span>glucose<span>. Hope this helps. </span>
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes sperm and eggs.
A. The waves would be exactly the same at points A and B.
Explanation:
The seismic waves at both point A and B would be exactly the same at the two points.
Seismic waves are elastic waves that spreads out concentrically in all directions from their source.
- Both S and P waves are body waves that moves within the earth.
- In a seismic station, the p-waves or primary waves arrives first before the s-waves or secondary waves.
- At any point equidistant from the epicenter, baring any geologic differences in the subsurface, the waves would be exactly the same at all points.
