Some objects in space are created from clouds of gas and dust. A star forms when the mass of the dust cloud is large and has enough hydrogen to start creating a protostar and sustain the nuclear fusion reaction within the core of the protostar. If the dust cloud is not dense enough, then the star formation does not take place, rather a nebula is formed, example the Horse-head nebula. So the answer is (B) A star will not form.
A few questions in space are made from billows of gas and residue. A star shapes when the mass of the residue cloud is huge and has enough hydrogen to begin making a prostate and support the atomic combination response inside the center of the prostate. In the event that the residue cloud isn't thick enough, at that point the star arrangement does not occur, rather a cloud is shaped,
The tympanic cavity is an air chamber; it contains a chain of movable bones which transmit the vibrations of the tympanic membrane across the cavity to the middle ear.
If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.
