What is a low mass star (main sequence)?
A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)
The order in which the actions occur is known as sequence of what?
Sequence of Events.
What do you call events that occur in a sequence?
You call them 'sequence of events'.
What is the stage after red giant for a low or medium mass star?
White dwarf is the most common answer if you are thinking of the red giant as the entire time a star swells to more than its main sequence size.However, the stages of a star actually occur in this order.After a medium mass star reaches red giant phase (second brightest phase), its core contracts until it becomes so dense helium begins to fuse into carbon (helium flash) at which point the star enters its second burning phase, known as the horizontal branch (slightly less bright than red giant).This is the second longest phase of the star (if not considering dwarf phases which are not really stars, they are more like cooling coals after a fire).Hydrogen to Helium reactions still occur in layers surrounding the core. When the star's store of Helium is consumed, it begins what is called the asymptotic giant branch (brightest/largest phase) where it again swells in size before pushing its otter layers off to form a planetary nebula.Eventually this nebula floats away leaving the cooling carbon core known as a white dwarf which will eventually cool to a black dwarf over billions of years. (This is not to be confused with a brown dwarf which is a slightly less than a stars sized object that never will never have the temperature to fuse hydrogen.There are currently none or very few black dwarfs present because the universe is not yet old enough for white dwarfs to have cooled.This is the simplest correct answer I could give. If you are in first years of highschool or below you might want to write it all down because the likely hood of you teacher actually knowing the right answer is slim. More than likely they will assume a star moves straight from a red giant to white dwarf.Unfortunately you can get answers marked wrong because of their stupidity.
How and why variation occur in rate and sequence of development and learning?

Why are giants not on the main sequence?
Because, giants can only occur once they leave the main sequence.
What is the definition of sequence of events?
in order in which events occur.
What are known as gene mutations and occur at a single point in the DNA sequence?
Mutations that occur at a single point in the DNA sequence are Point Mutations.
How does a mutation occur?
A mutation is a change from the expected nucleotide sequence of DNA. It can happen when nucleotide bases are duplicated or deleted from the sequence.
What type of galaxys are nebulas often found in?
There are many types of nebula and they can form within any galaxy. Generally, the normal types of nebula - planetary and supernova remnants will occur in the younger galaxies, so at a push spiral galaxies.
Where did the battle sequence occur in real life?
in a shell around the core
Sometimes random mistakes occur in a DNA sequence. These mistakes are referred to as .?
