Answer:
Gravity is a force that combines all the particles of "interstellar cloud" together to form a star.
<u>Explanation:</u>
A star is a "luminous ball of gas" made from the gases of helium and hydrogen and it is held under the action of gravity. Sun is the nearest star present to the earth and the nuclear fusion process is proposed to develop various stars in the galaxy.
Interstellar cloud indicates the combination of various gas, plasma, dust in the galaxy. This cloud contains 16 hydrogen atoms for every helium atom and also contains traces of carbon, iron and nitrogen atoms.
Gravitational force compresses the interstellar cloud and triggers them to result in a star.

<span>Refraction happens when there</span> is a bending of path of a light wave as it
passes across the boundary separating two media and the degree of bending is
determined in part by the total change in velocity as the light<span> passes from one medium to the other. In
addition, the change in speed experienced by a
wave when it changes medium can result in a number of beautiful optical effects. </span>
The differences between the dog breeds are due to genetic factors. All dogs belong to the same species, so these differences are due to genetic variations. Each dog inherits genetic traits from its parents, such as the type or color of hair. This information is found in segments of DNA called genes.
