Answer:
It is how something has been developing/developed over a certain time period starting off simple to become something composite. It has an advancement or growth to it. In other words it is something that progresses throughout time and has a change in transformation.
Once massive stars reach the red giant phase, the core temperature continues to increase as carbon atoms are formed from the fusion of helium atoms. Gravity continues to pull together the carbon atoms in the core until the temperature reaches 600,000,000 degrees Celsius. At this temperature, carbon atoms form heavy elements such as oxygen and nitrogen. The fusion and production of heavy elements continues until iron starts to form. At this point, fusion stops and the iron atoms start to absorb energy. This energy is eventually released in a powerful explosion called a supernova. A supernova can light the sky up for weeks. The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion. The core of a massive star that is 1.5 to 4 times as massive as our Sun ends up as a neutron star after the supernova. Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars. The core of a massive star that has 10 or more times the mass of our Sun remains massive after the supernova. No nuclear fusion is taking place to support the core, so it is swallowed by its own gravity. It has now become a black hole which readily swallows any matter and energy that comes too near it. Some black holes have companion stars whose gases they pull off. As the gases are pulled down into the black hole, they heat up and give off energy in the form of X-rays. Black holes are detected by the X-rays which are given off as matter falls down into the hole.
The three-dimensional extension of the Norwegian cyclone model includes warm and cold air streams called conveyor belts.
- The warmth from below will cause a cold air mass traveling away from its source region over a warmer surface to become more unstable. Upon passing over a cooler surface, the warm air mass is cooled from below, stabilizing it at the lowest levels.
- According to four major source regions with respect to latitude, air masses are frequently categorized. The four are tropical (warm and humid), polar (cold), and arctic (extremely cold) (warm). When warm, humid air from the south moves northward, it overruns the cooler, dry air that is located north of the stationary front.
- Due to the fact that cold, dry air is heavier than warm, moist air, this occurs. Such circumstances frequently result in precipitation in addition to dense cloud cover.

The nursing student should include the information about Pap smear does
not test directly for HPV, dysplasia of cervical cells is strongly associated
with HPV infection. An abnormal Pap smear is not indicative of chlamydial
infection or candidiasis. There is a chance that these will clear up on their
own. HPV infection is not correlated with pelvic inflammatory disease (PID).
