Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions. Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive. From that information, scientists can determine how fast the waves are traveling. Knowing this helps them calculate the distance from the epicenter to each seismograph.
To determine the direction each wave traveled, scientists draw circles around the seismograph locations. The radius of each circle equals the known distance to the epicenter. Where these three circles intersect is the epicenter.
Answer:
A <u>fetal death</u> is death prior to the complete expulsion or extraction from its mother in a hospital facility, of a product of human conception (fetus and placenta), irrespective of the duration of the pregnancy and without any signs of life.
Explanation:
Due, to lack of nutrition or care some mothers loses there new born before the delivery, while most of the time such miscarriages results in the death of the fetus that is yet to be developed properly inside the womb of its mother. It all can happen due to mental, emotional, or physical stress on the female. However, it can be prevented by providing proper care to the mother and having the best of procedures to deal with any situation faced during the development of the fetus or offspring during the tenure of pregnancy.
Answer:
Topoisomerase
Explanation:
Topoisomerase is an enzyme that is involved in the unwinding of Deoxyribonucleic acid (DNA). They are involved in double stranded DNA and they help to relieve the making of supercoils.
Topoisomerase play an important role during DNA replication, as the prevent the the twisting of the DNA double helix ahead of the replication fork. In other words, they ensure that the DNA open up for unwinding without being tightly wound.
