Life cycle of a star Stars are born in nebulae. Huge clouds of dust and gas collapse under gravitational forces‚ forming protostars. These young stars undergo further collapse‚ forming main sequence stars. Stars expand as they grow old. As the core runs out of hydrogen and then helium‚ the core contacts and the outer layers expand‚ cool‚ and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. Its fate

Organizational Life Cycle Organizational life can be as unpredictable as the weather‚ but it is somewhat predictable in stages of development. Like the human life cycle from birth to aging and death‚ some organizations have a comparable life cycle. Unlike the human life cycle‚ which moves for everyone through physical stages‚ the organization cycle is not inevitable. We use this metaphor to help leaders understand what can happen‚ usually as a result of inappropriate leadership. To grasp the nature

Butterflies go through a life cycle. There are four stages. The first stage is the eggs. This is where a girl butterfly lays eggs. She lays them on a leaf. The second stage is the caterpillar. This is where the eggs hatch. It takes about five days for the eggs to hatch. A caterpillar then comes out. At this stage‚ the caterpillar eats all the time. It also grows really fast. Once it is all the way grown‚ the third stage starts. This stage is the chrysalis. The caterpillar makes a chrysalis. The caterpillar

Page 1 of 6 Life Cycle of Malaria Page 2 of 6 Malaria is an ancient disease transmitted by the Anopheles mosquito that predates recorded history. Historically it was common in the swampy areas around Rome‚ and was believed that the tainted air in those locations made people very sick‚ the disease was therefore named malaria for the Latin root words bad air. Malaria is caused by small parasitic protozoa of the genus Plasmodium which infects both humans and mosquitoes in a cyclical process.

loyalty as publicly as McDonald’s and Burger King. The rivalry dates back to the mid-20th century as both companies emerged on the national scene‚ battling for territory and franchisees. The burger business is all about share of stomach. There are only so many ways you can innovate when it comes to a hamburger‚ so copying competitors’ ideas is standard practice. Take the Big Mac‚ which was launched in 1968 as McDonald’s answer to the Whopper. Burger King introduced the Whopper in 1957 when‚ after

The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

the core as a gaseous shell. The gas that surrounds the core is called a "Planetary Nebula". The core that is left then becomes a "white dwarf". After the white dwarf cools down enough it stops shining and dies‚ forming a "black dwarf". Another life cycle of a star involves a star with a mass of 10 solar masses or more. These stars evolve similarly to stars of about 1 solar mass until they reach "main sequence". The star shines bright until all of its hydrogen has fused to form helium. This takes

Forget for a moment all the recent talk about Burger King Corp. and Wendy ’s International Inc. stealing customers from McDonald ’s. With a 42% share of the U.S. fast-food burger market‚ McDonald ’s still easily outpaces its rivals. Nonetheless‚ the problems under the famous Golden Arches are far more serious than a failed Arch Deluxe here or a french-fry war there
