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

The Life Cycle Hypothesis The Life Cycle Hypothesis (LCH) is an economic concept analyzing individual consumption patterns. It was developed by the economists Albert Ando and Franco Modigliani. The theory is based on the observation that people make consumption decisions based on the income and resources they are expected to earn over their lifetime and at which stage of life they are at. The theory considers that individuals plan their consumption and savings behavior over the long term and intend

Product Lifecycle Management Stage 4: Decline The decline stage of the product life cycle is the one where the product ultimately ’dies’ due to the low or negative growth rate in sales (see Figure 1). Profitability will fall‚ eventually to the point where it is no longer profitable to produce‚ and production will stop. As a number of companies start to dominate the market‚ it becomes increasingly difficult for the company in question to maintain its level of sales. Consumer tastes also change

Life Cycle of Bacteriophage. Bacteriophage: Bacteria eating virus is called bacteriophage. Life Cycles: There are 2 types of lifecycles that occur in the bacteriophage: 1) Lytic Cycle 2) Lysogenic Cycle 1) Lytic Cycle: In lytic cycle‚ virus that is the bacteriophage causes lysis of the host cell. It is virulent phage. 2) Lysogenic Cycle: In lysogenic cycle‚ the bacteriophage does not cause lysis

The Cnidarian is known for its life cycle. There are two stages of life involved called the Polyp and Medusae. The polyp is the plant life of the sea that is usually tubular and attached to stationary objects within the water. The tentacles on the polyp are usually pointed upward and flared out to atract and pull in prey. The Medusae is the jellyfish looking creature. They float around in the water and look like umbrellas. The mouths are located on the Concave or the inside of the creature with
