Your wording is a bit confusing, but I get what you're trying to say.
Here's what the life cycle of a star looks like.
Stars begin as giant balls of hydrogen colliding together and releasing a ton of energy. This hydrogen will eventually fuse together to form helium, and once all of the hydrogen has become helium, This helium will, after a very long time and under lots and lots of pressure, form carbon. When this happens, it is considered a red giant, and the star becomes bigger and less bright. The star will become less and less bright and eventually start to shrink as all of that carbon turns to heavier elements like iron, turning into a dwarf star that eventually dies out.
(Dwarf stars are still shining are called white dwarf stars, and dead ones are black)
The cool part, though, is that massive stars (those which have a mass of at least 3 times the Sun's) turn into heavy elements so fast that the core collapses almost instantaneously and explodes violently into a ball of fire known as a supernova.
Sometimes the core of the star gets left behind, and either forms a neutron star or, if it has the mass of a massive star, will collapse in on itself and become a black hole.
Answer:
Polygenic inheritance
Explanation:
When multiple genes present at different loci on chromosomes regulate a single genetic trait, the trait is said to be polygenic and the inheritance is a polygenic inheritance. The phenotype of the individual is regulated by an allele of each gene in an additive manner. The sum total of phenotypic effects of each allele of all the genes determines the final phenotype of the individuals.
These traits not present in discrete contrasting pairs (such as tall and short) but exhibit quantitative variations. For example, skin color in humans is regulated by multiple genes and the phenotype of the individual ranges from very light to very dark with many intermediates in between.
Answer:
Electricity flows by the movement of electrons through conductors. If a bird perches on a wire with two feet there is no motivation to go through the birds' body so electrons choose the path of least resistance and continue to flow along the wire.
Explanation:
Answer: The Moon's gravity causes ocean to bulge.
Explanation:
Ocean bulge occur when the gravitational attraction between earth and the moon causes the water in the oceans which can move to be attracted towards the moon. This causes a bulge in the ocean that is closest to the moon as the earth rotates and the location of the effected water changes.
