What evidence shows that white dwarfs must be very small?

1 answer:

7 0

Spectral analysis proposes that there is no hydrogen fusion roughly speaking. They are hot since they are very thick. So if you are a convinced high density and temperature and still not doing synthesis, you must be small. Also, stellar evolution models are founded on the observation of planetary nebulae, where stars have shed most of their mass after being red giants. The physics designates a small, hot, central remainder.

Leokris [45]

The answer is Hemispheric lateralization. It distinguishes between alpha activity in the left and right sides of a brain and is used to determine how an ad is affecting the mental processes of the individual viewing it. It is the distinction between functions of the right and left hemispheres of the brain. If one hemisphere is more heavily involved in a specific function, it is often referred to as being dominant.

inysia [295]

Answer:

They are called Stomatas.

Explanation:

A waxy cuticle covers all aerial surfaces of land plants to minimize water loss. These leaf layers are clearly visible in the scanning electron micrograph. The numerous small bumps in the palisade parenchyma cells are chloroplasts.
