Q: Some aspects of a system's carrying capacity may involve matters such as available supplies of food, water, raw materials, and/or other similar resources. In addition, there are other factors that govern carrying capacity which may be less instinctive or less intuitive in nature, such as ever-increasing and/or ever-accumulating levels of wastes, damage, and/or eradication of essential components of any complex functioning system. Eradication of, for example, large or critical portions of any complex system (envision a space vehicle, for instance, or an airplane, or an automobile, or computer code, or the body components of a living vertebrate) can interrupt essential processes and dynamics in ways that induce systems failures or unexpected collapse. (As an example of these latter factors, the ''carrying capacity'' of a complex system such an airplane is more than a matter of available food, or water, or available seating, but also reflects total weight carried and presumes that its passengers do not damage, destroy, or eradicate parts, doors, windows, wings, engine parts, fuel, and oil, and so forth.) Thus, on a global scale, food and similar resources may affect planetary carrying capacity to some extent so long as Earth's human passengers do not dismantle, eradicate, or otherwise destroy critical biospheric life-support capacities for essential processes of self-maintenance, self-perpetuation, and self-repair.
Can we conclude that available raw materials are one of the limiting factors regulating carrying capacity?

In the U.S., demand deposits only refer to funds held in checking accounts (or cheque offering accounts) other than NOW accounts; however, in a 1970s and 1980s response to the 1933 promulgation of Regulation Q in the U.S., demand deposits in some cases came to allow easier access to funds from other types of accounts (e.g. savings accounts and money market accounts). For the historical basis of the distinction between demand deposits and NOW accounts in the U.S., see Negotiable order of withdrawal account#History.

Problem: Text: Documents other than those listed above, including Canadian passports, are not considered as proof of citizenship, but a passport is issued only after review of other documentary proof, as noted above. Church-issued baptismal certificates and birth certificates issued by an authority other than a provincial or territorial government are also not proof of Canadian citizenship. Such certificates were common in Quebec, as the provincial government did not start to issue birth certificates until 1994.

Question: can a canadian passport be used as proof of citizenship?

IN: Is it true that does the duck die in peter and the wolf?

Peter's grandfather scolds him for being outside in the meadow alone (''Suppose a wolf came out of the forest?''), and, when he defies him, saying: ''Boys like me are not afraid of wolves'', his grandfather takes him back into the house and locks the gate. Soon afterwards ''a big, grey wolf'' does indeed come out of the forest. The cat quickly climbs into a tree, but the duck, who has jumped out of the pond, is chased, overtaken, and swallowed by the wolf.
