After the star's outer layers are expelled, the density of the remaining material is typically too low to provide adequate energy to sustain the hydrogen-burning shell's nuclear temperatures, and the remaining star easily contracts to form a white dwarf (a star with a density equal to the Sun, but a diameter equal to the Sun).
Ummm ... true , but im pretty sure.
For a person with blood type A- (A negative), they can be transfused with either blood type A negative , or blood type O negative.
This is because any other blood type will immediately be rejected by their body.
A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against any other blood type of a different group such as B and AB, even if they are rhesus negative.
Therefore because of the rhesus negative factor, a person with blood type A negative can only be transfused with rhesus negative .
he left and right hemispheres are connected by the cerebral commissures. Thus, the correct option is C.

What is cerebral commissures?</h3>
Three tracts of nerve fibers or axons connect the right and left cerebral hemispheres, and these are referred to as commissures cerebral.
The corpus callosum, anterior commissure, and posterior commissure are three transverse nerve fiber bundles that connect homologous parts of each hemisphere.
The corpus callosum, also known as the great cerebral commissure, is the largest, connecting the majority of the cerebral hemispheres and allowing the cerebral cortex to function as a whole.
