Answer:
Saliva lubricates and moistens these food particles
Explanation:
As teeth help to break down large pieces of food into lots of smaller pieces, saliva is released and mixes with the smaller food pieces. Saliva lubricates and moistens these food particles such that a ball-like mixture of food and saliva that is known as a bolus is formed, which can then be easily swallowed.
Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
