In which order did the events forming our solar system occur? the solar nebula flattened into a rotating disk. as gas became hot and dense, it spun faster and faster and was pulled toward the center, forming the sun. gas was pulled toward the center, forming the sun. gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster. gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster. gas was pulled toward the center, forming the sun. the solar nebula spun faster and faster and flattened into a rotating disk. most of the gas was pulled toward the center, where it became hot and dense, forming the sun.

1. An accretionary disk formed

2.A protosun formed

3.Rings formed in the protoplanetary disk.

4.Planetesimals collected to form protoplanets

The correct answer is A. The solar nebula flattened into a rotating disk. As gas became dense and hot, then it spins faster and pulled towards the center whereby the sun is formed.

Solar nebula they collapse where the protostellar disk rotates. In the center of of nebula, there is a fusion begins and then sun is being formed.

The other molecular clouds they flattened to protoplanetary disk whereby the asteroids, planets, moons, and other small systems of solar are being formed.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
