The SP timing method is a technique, which is useful for finding the epicenter of the earthquake. The Seismograph at a particular station shows the S and the P waves. The difference between the S and the P waves can be used to determine the distance, which waves have travelled in order to reach the seismic station.
The distance obtained is the distance of the epicenter from that seismic station, in order to determine the epicenter the circle is drawn in the map keeping the seismic center at the center. Same process is done by three or more seismic centers. The point, where the circle drawn by three or more seismic centers meet is considered as the epicenter.
Hence, the correct answer is Three.
Answer:
The correct answer is eukaryotes engulfed photosynthesizing prokaryotes
Explanation:
The endosymbiotic theory or symbiogenesis is an evolutionary theory that traces the origin of eukaryotic cells from prokaryotic organisms. It explains that some of the organelles (Mitochondria and Chloroplasts) in eukaryotic cells evolved from free-living prokaryotic microbes which were ingested or engulfed. The ingested prokaryotic cells survived within the organism and developed a symbiotic relationship.
According to the theory, chloroplasts was formed when eukaryotes engulfed photosynthesizing prokaryotes and mitochondria was formed when bacteria capable of aerobic respiration were engulfed.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.
<span>In this population, what will occur is that there will be no evolution. Mutation is neccessary and important because they provide varitations that can result in evolutionary change. Other factors needed for evolution to occur are migration and selective pressure.</span>
Answer:
The central angle is 20% of 360°, that is
central angle = \frac{20}{100}
100
20
× 360° = 0.2 × 360° = 72° → C
