Answer:
Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. About first millisecond, the universe had cooled to a few trillion kelvins (1012 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers. The abundance ratio was about seven protons for every neutron. Before one neutron half-life passed nearly every neutron had paired up with a proton, and nearly every one of these pairs had paired up to form helium. By this time the universe had cooled to a few billion kelvins (109 K) and the rate of nucleosynthesis had slowed down significantly.

Answer:
What abiotic aspects of an ecosystem can be affected by biotic aspects?
animals digging in the ground adding to soil erosion
Explanation:
Abiotic factor that could be affected by biotic factor entails the digging of ground which aids soil erosion.
Domain Archaea
Like bacteria,Organisms in domain Archaea are prokaryotic and unicellular. Superficially, they look a lot like bacteria, and many biologists confused them as bacteria until a few decades ago.
The Human ES Cell
Culture or Embryonic Stem Cells.
They capture the thoughts because they are unforgettable and have an entire limitless developmental capability. After few months of growth, these are extraordinary cells kept maintaining the ability to create another cell ranging from muscle to nerve to blood inside the body. Any cell has the potential that makes up the body.
