If a star of 50 solar masses were to supernova. It would most likely become a black hole.
A star is a hot body of glowing gas which starts its life in Nebulae. The stars vary in size, mass and temperature. The mass of a star ranges from 1/20 times to 50 solar mass.
The stage one of the stars is born in nebula, which is a region of very high density and then it gets condensed to a huge globule of gas and dust that contracts under its own gravity.
The next stage is a region of the condensing matter which starts heating up and glowing is known as Protostar. At stage three, hydrogen fuses and forms helium as the nuclear reactions start. Stage four is a Main Sequence star when it starts to release its energy, contraction stops and it begins to shine.
Some of the stars have mass more than 3 times of the Sun and up to 50 times the mass of the sun.
When the surviving core is between 1.5-3 solar mass, with higher contraction making it tiny and dense a Neutron star is formed. If the core is greater than 3 solar masses then the core further contracts to become a Black Hole.
Answer:
I think its D sorry if you get it wrong
During a
head injury or a trauma, the brain can limit the spread of the damage by
forming a glial scar which seals off the damaged region from the rest of the
important parts. During this process, the glial cells are particularly
important. In specific, the glial cells Astrocytes will be the most abundant in
this process since they produce glucose and other essential nutrients which help
support the viability of the surviving cells. In addition, the astrocytes is responsible in maintaining the
brain environment stability (homeostasis), supplying nutrition for neurons, and
recycling neurotransmitters.
Therefore the answer to
this question would be:

The answer is; glucose
It is a 6 carbon ring simple sugar and is the most abundant monosaccharide in the body. Its levels in the body are referred to as blood sugars. Larger carbohydrates consumed in the diet are broken down to glucose utilized in respiration (Glycolysis and Krebs cycles) to produce the energy required by the cells. Plants, on the other hand, manufacture carbohydrates in photosynthesis.
