A large cloud of gas (hydrogen) and dust a nebula begins to collapse
The collapsing cloud begins to spin
The spinning collapsing cloud flattens into a rotating disk
Material in the disk begins to accumulate in the center
As the material coalesces in center, it becomes dense, compresses, and heats up.
More and more material coalesces to form a protostar.
The protostar continuse to accomulate material from the surronding disk and grow.
Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of nuclear fusion to begin.
Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.
Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.
Then the young star stops accumulating material.
d, because it takes in glucose (chemical energy) and created atp(chemical energy). photosynthesis is similar but it uses light energy instead of chemical energy.
Answer;
-Step E
Explanation;
-The lysogenic cycle is a viral replication cycle
that does not kill the host immediately. The lytic cycle is the other type of viral replication cycle that results in the destruction of the infected cell and its membrane.
-All viruses undergo a replication cycle in their human host cell consisting of adsorption, penetration, uncoating, nucleic acid replication, maturation and release stages. During the maturation and release stage the virus release a protein that causes the cell wall to burst.
Erosion transports/spreads broken down minerals while weathering is the processes of rocks and earth minerals being broken down.
