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.
A chemosynthetic bacteria is a producer. Chemosynthetic bacteria produce energy by using chemical reactions similar to photosynthesis but without the light as a catalyst. A chemosynthetic bacteria can produce organic molecules (i.e. glucose) from inorganic molecules just like photosynthetic organisms.
Answer:
cells are the basic building blocks of living things
:/ uuuuuum i dont know lol
Answer:
chimpanzees
Explanation:
humans chimpanzees gorillas orangutans and their extinct ancestors humans chimpanzees gorillas orangutans and their extinct ancestors form of the family of organisms known as the hominidae. Researchers generally agree among the living animals in this group, humans are most related to chimpanzees judging from comparisons of anatomy and genetics.
