Answer:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Explanation:
he “population growth rate” is the rate at which the number of individuals in a population increases in a given time period as a fraction of the initial population. Specifically, population growth rate refers to the change in population over a time period, often expressed as a percentage of the number of individuals in the population at the beginning of that period. This can be written as the formula:
population
growth
rate
Globally, the growth rate of the human population has been declining since 1962 and 1963, when it was 2.20% per annum. In 2009, the estimated annual growth rate was 1.1%. The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.89%, 0.79%, and 1.096% respectively. The last 100 years have seen a rapid increase in population due to medical advances and massive increase in agricultural productivity.

Heat cannot transfer energy in vacuum. Only electromagnetic radiation can. Therefore heat transfer processes such as conduction and convection require a medium. By introducing vacuum between the inner and outer walls of thermos flask, heat loss from the content in the flask is drastically reduced because heat cannot transfer through the vacuum to the outer atmosphere.
Anxious and apprehensive are signs that the patient doesn't have enough blood to his brain. The cause probably is the low blood pressure. <span>
Open abdominal surgery is a major surgery so it should have a high risk of bleeding. </span>Bleeding in abdominal space is dangerous because it was not visible and space is massive. The source could be a rupture of a blood vessel or broken stitch of the surgical wound.
