In massive stars, fusion is generally produced in a catalytic cycle of reactions known as the Carbon-Nitrogen-Oxygen cycle. Some large stars use the Triple-Alpha process to transform helium into carbon. In massive, contracting stars, fusion can also be produced in the Neon Burning process and the Oxygen Burning process. And finally, there is the Silicon Burning process that produces iron.
In lighter stars, like our Sun, the Proton-Proton chain process is used to convert hydrogen into helium.

What type of fusion occurs in a high-mass star near the end stages of its life cycle?
helium capture
What is a limiting factor to the amount and type of fusion that occurs in stars?
The mass of the star and the related temperature of the stellar core determine the thermonuclear process type of the star. The stars of the solar mass produce energy from Hydrogen in the proton-proton cycle (two and three proton nuclei appear in intermediate stages of the fusion, end product is Helium); stars twice (or more) as heavy run the HNC cycle (Although Helium is here still the end product, Nitrogen and Carbon appear in intermediate fusion stages, too). Once the Hydrogen is used up, gravity collapse makes the temperatures rise until the next , heavier element fusion cycle is activated. As the temperature rises, other numerous fusion cycles can produce all existing elements. The heaviest ones are created in the extraordinary high temperatures of the supernovae-explosions
What layer of the sun does fusion occur?
Nuclear fusion occurs in the solar core.
Where does nuclear fusion happen on the sun?
Only at the core, where the temperatures and pressures are high enough.
Does nuclear fusion occurs at cooler temperatures away from the Sun?
Yes, in Red Dwarf Stars. However, the temperatures required for fusion are still pretty high, millions of degrees Celsius.

What type of fussion occurs in a high mass star near the end stages of its life cycle?
In that case, the temperature is hot enough to create all known natural elements.
What are facts about nuclear fusion?
Nuclear fusion releases huge amounts of energy. It occurs when the nuclei of elements are fused together at high temperatures and high pressure. Fusion energy is used to produce energy for some of the Earth's cities.

Only at the core, where the temperatures and pressures are high enough.
Does nuclear fusion occurs at cooler temperatures away from the Sun?

What are the technical problems relatd to nuclear fusion?
Nuclear fusion normally occurs at high temperatures and pressures. A fusion reaction would melt the container and would have to be suspended by a magnetic field in a vacuum and the container would have to be continually cooled to prevent a meltdown.
Nuclear fusion requires extremely high?
Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.
The female reproductive cycle menstrual flow occurs when the concentrations of what are low or high?
low estrogen and low progesteronekris
What are the technical problems related to nuclear fusion?
Nuclear fusion requires very high temperatures and immense pressures to start and continue. The problems with a nuclear fusion reactor would be:- 1) the high temperatures would melt the container: therefore, the reaction would have to be stored in a vacuum suspended by a magnetic field and the reactor would have to be continually cooled. 2) nuclear fusion occurs naturally in stars such as our sun: unless the fusion reaction was limited in size in some way, it would be likely that our planet is vapourised by the reaction.
Why must an extremely high energy level be reached before a fusion reaction can take place?
Fusion occurs because two nuclei are colliding to create a new nucleus. Because the atoms are positively charged, they naturally repel each other, so high amounts of energy are required to counter-act this force.
