The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.
I hate to ask and sound stupid, but the drug or the basic chemical?
<span>The common difference between the three organisms
is the area in which they specifically live or stay in the ocean. Planktons can’t
be seen by the naked eye and they require microscopes to be detected. Planktons
usually float in the water and they cannot move on their own that’s why they
are dependent in the movement of the water.
Nektons are organisms that swim through the water and they live in different
depths in the ocean ecosystem. Nektons are composed of fish and other mammals
that propel themselves through the water.
Benthos are organisms that live in the ocean floor and many of these organisms
stay in one place by attaching themselves to rocks. This adaptation protects
them from crashing waves and drastic water movements. Other benthos are known
to burrow in the ocean floor either for food or protection.</span>
