The theory considers that individuals plan their consumption and savings behavior over the long term and intend

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

Toads tend to lay many many eggs because there are many hazards between fertalization and full grown frogness! Those eggs that die tend to turn white or opaque. The lucky ones that actually manage to hatch still start out on a journey of many perils. Life starts right as the central yolk splits in two. It then divides into four‚ then eight‚ etc.- until it looks a bit like a rasberry inside a jello cup. Soon‚ the embryo starts to look more and more like a tadpole‚ getting longer and moving about in it’s
