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.
I be;live the awnser is they all have plants and animals but i could be wrong
Answer:
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.
Explanation:
Answer:
C) run a statistical analysis on the data collected
Explanation:
A) False
You can only start investing in drug company after analysing all the results of the experiment, then you need to develop the drug correctly so then you can start making experiments with a larger amount of pacients to test the efiiciency of the drug so finally you can sell it.
B) False
You can only conclude this after reviewing the results. Without analysis, nothing can be concluded.
D)False
You only start a new hypothesis after the first one has been rejected by data analysis. If the drug has no effect on patients, a new hypothesis will need to be developed. But you will only know this after analyzing the results of the experiment.
