Gravity is a force that acts between any masses. Gas and dust have mass, ergo, they are affected by gravity and exert gravity themselves.
Stars develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion. This process starts in the core of the collapsing cloud, where the temperature and pressure become high enough for nuclear reactions to occur, initiating the star's life cycle.

Gravitational force is what causes protostars to form. Gravity pulls together gas and dust in a molecular cloud, causing it to clump and collapse, eventually leading to the formation of a protostar.
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
Dust on the moon does not float because there is no atmosphere on the moon to support floating particles. Without air resistance and buoyancy, the dust simply settles back down to the surface due to the moon's gravity.
Gravity is the force that pulls dust and gas together in space. The gravitational attraction between particles causes them to clump together, eventually forming larger structures like stars and planets.
A protostar forms when gravity pulls the dust and gases in a nebula together.
True.
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.

It pulls you toward the planet's core.
Gravity.
The first stage is that a star enters as a ball of gas and dust. The second stage is that gravity pulls the gas and dust into a sphere. The third sage is that as the sphere becomes denser and it gets hotter and the hydrogen changes into helium in a process called nuclear fusion.
"Clouds" of gas (and dust) concentrated by gravity.
These clouds are known as nebulae, where stars are born. Gravity pulls the gas and dust together, forming dense regions that eventually collapse to form new stars. Nebulae are of great interest to astronomers as they provide insights into the process of stellar formation.
The list of choices posted with the question doesn't include anything that fits that description. It sounds something like a "star", but in a star, it would be "fusion", not "fission".
