Define Nucleosynthesis and describe what it was like in the first few minutes after the Big Bang

Biology
1 answer:
In-s [12.5K]3 years ago
5 0

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.

What would cause an individual to have a mutation in all of their cells?
Stella [2.4K]

Answer: These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.

Hope that helped

F is the symbol for Force! The units of force are newtons or because force is made up of mass (kg) x acceleration (meters/second squared) we can say the units for force is just a blend of these.

So units for force is newtons or kg per meter squared.

Both of these units are correct for force.



M is the symbol for Mass! The units for mass are kg


A is the symbol for acceleration, the units for acceleration are meters per second per second ( ms^2)

Was the streak plate method effective at diluting the population size in all 4 plates?
Inessa05 [86]

Answer:

"Yes" The streak plate method is very effective in diluting the population size in all 4 plates.

Explanation:

The streak plate method is effective because it is one among the rapid isolation method which further allows for easy observation of the bacteria. This method is also being used for getting the color of the certain substances. Its main principle is to isolate the specific bacteria from the sample of various microbes. It dilutes the microbes number and often reduces their density. It is useful in separation of organisms from the group. These are isolated in the agar plate.
