certain minimum population base needed for a population to survive and recover.
a critical number is the minimum number of individuals of a given species that is required to maintain a healthy population. if a population goes down below thew critical number then it will become extinct
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
Yes, reactor number 3 is really in critical at Fukushima.
The number of people in a given area
Lower critical mach number may be defined as the highest subsonic mach number below which the entire flow over it is subsonic. vijayaprakaash
The Marangoni Number is a Peclet Number. It is the ratio between the surface forces due to the Marangoni effect and the thermal diffusivity. The Critical Marangoni Number is the value of the Marangoni Number for which the flow symmetry and steadiness are lost.
plants
so you can know the number of animals there are in the species
Please clarify.

Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
