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:
1) Basilar membrane
2) Stereocilia or hair cells
3) Nerve cells
4) Auditory
5) Temporal lobe
Explanation:
Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.
Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.
Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.
Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.
Answer:
A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.
Explanation:
Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.
Only about 3 percent of the worlds water is fresh, and even less than that is usable, because most of it is locked up in glaciers or in permanent snow fields.
The correct answer is D.
Answer:
well athlete parents maybe or parents that used to ski, im not sure since learning how to ski and getting good at is isnt really part of genetics
