Drag each tile to the correct location. Not all labels will be used. Identify the phases in the life cycle of small and big stars. supernova: In this stage, the star collapses and produces elements heavier than iron. planetary nebula: In this stage, the star emits strong energy pulses that push away the outer layers creating a cloud of ionized gas around the core. neutron star: In this stage, the star has reduced to an extremely dense core. white dwarf: In this stage, the star has reduced to a dense core.

ALL STARS BEGIN IN A STELLAR NEBULA / NEBULA

Depending on how much mass the star has, it changes what path of life cycle it will take. Low mass or average mass stars become an average star, also called a main sequence star. It swells after millions of years into a Red Giant which is GIANT. Many many many years later, it becomes a planetary nebula and finally becomes a white dwarf.

If the star has a large mass, it is classified as a massive star, and also goes through a form of the main sequence. It swells into a MASSIVE GIANT TREMENDIOUSLY LARGE AND UNNECESSARILY BIGGO star called Red Supergiants. After millions and billions of years, it becomes a Supernova, which finally becomes a black hole if the outer layers literally get blown off into space, and the core collapses and gets compacted into incredibly dense Nano-Googleplex sized molecules. If it doesn't, it becomes a cool Neutron Star.

YOU DIDN'T GIVE ME ANY TILES OR LABELS

Explanation:

 1.  average star to giant to planetary nebula to white dwarf

2.  massive star to supergiant to supernova to neutron or black hole

Explanation:  I just took the test and this is correct

the answer is sex-linked recessive.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
