D. To process information and form a response
So by looking at the seismic waves from earthquakes the scientist learned about the crust and the mantle but they also learned about the outer and inner core. To do this you have to look at a different kind of waves, the S (secondary waves) waves that also get released by an earthquake.
- Progressive dilating and obliteration are the physiological changes the nurse would anticipate after an amniotomy is performed.
- The fetal head can press more forcefully against the cervix thanks to the artificial rupture of the membranes (amniotomy), which improves dilation and effacement.
- As labor progresses, vaginal bleeding may become more severe. The fetal heart rate is not immediately impacted by amniotomy.
- Because contractions typically intensify and become more frequent when the membranes are artificially ruptured, discomfort may worsen.
<h3>What is Amniotomy?</h3>
- Artificial rupture of membranes (AROM), often known as amniotomy or simply "breaking the water," is the deliberate rupture of the amniotic sac by an obstetrician.
- This treatment is frequently carried out during labor management and has a variety of indications.

Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
