Answer:
Convective zone, chromosphere, corona
Explanation:
A star like the Sun is divided into different layers according to pressure, density, temperature, and the mechanics of energy transport (in the case of the convective zone and radiative zone) for each of those layers.
In stars, there is an equilibrium between two forces, the force of gravity in the inward direction due to their own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in their core, that is known as hydrostatic equilibrium.
That leads to different layers according with the properties described above.
Near the core, in the Sun, there is a radiative zone since radiation is the best mechanism of energy transport in this area. Then, in the next layer, it can be found that convection becomes a more efficient way of energy transport that radiation due to the fact that the inner part of the convection zone is at a greater temperature than the outer one.
Finally, there is the atmosphere of the Sun (chromosphere, photosphere, and corona).
Key terms:
Convection: Transport of energy due to different in density and temperature of a material (liquid, gas).
The human beings use 10 % of the brain and the remaining 90 percent is full of unused potential and undiscovered abilities.
Explanation:
It is stated that every human beings use 10 percent of their brain and the other 90 percent is used only for operating a limited stretch. the average adult human brain can store the 2.5 million gigabytes digital memory.
The human brains contains about 100 billion neurons and around i quadrillion to 1 million connections in the cells. The dendrites provide more information than passive wiring.
The unused part of the brain is not necessary it simply occupies the space. The damaged parts of the brain should be removed.
