As a general rule, IRAs have an annual contribution limit of $5,000 per individual. There are income limitations which limit which IRA you can contribute to, for example, deductible IRAs, Roth IRAs and non-deductible IRAs.
The pH range is from 0 to 14, with 7.0 being neutral. Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. Human blood stays in a very narrow pH range right around (7.35 - 7.45). Below or above this range means symptoms and disease.
Humans are homeotherms like most mammals. This means that we are warm blooded animals and have to regulate our internal body temperature. The ideal temperature range for a human body is 37Â°C. If there is even a 5Â°C drop or rise in body temperature, it could spell doom for the human being.s you can see, the temperature range within which a human can survive is very narrow. This makes one wonder what regulates body temperature in humans. This is especially quite intriguing as the external environmental temperature ranges are totally different from the internal body temperature.
