Answer:
D. Warmed air sinks is not a normal convection cycle outcome
Explanation:
Warm air is buoyant and rises. Cold air is dense and sinks.
Think of fog in the air. Fog forms in low/cool areas, as the sun comes out and warms up the atmosphere the upper atmosphere, heat flows to cold so upper atmosphere air displaces the fog.
Space heating, the steam or hot water radiators are placed along the floor typically causing convection of warm air to rise up over windows and cold walls, breaking up cold air drafts.
The stars that are only fusing hydrogen into helium at this time are :
<h3 /><h3>Characteristic of a star fusing hydrogen into helium </h3>
A star fusing hydrogen into helium is categorised as a main sequence star. As a star continues to fuse hydrogen into helium, energy is released in the process and the luminosity of the star increases as well. An example of a star that has completely fused hydrogen into helium is the sun. A giant red star signifies that the star is out of hydrogen it uses for nuclear fusion.
Hence we can conclude that the stars undergoing hydrogen fusion into helium are stars 1, 2 and 3

<span>Primary sources are original materials. They are from the time period
involved and have not been filtered through interpretation or evaluation.
Primary sources are original materials on which other research is based. They
are usually the first formal appearance of results in physical, print or
electronic format. They present original thinking, report a discovery, or share
new information. </span>
