Darwin realized that Malthus's theory of population control could be generalized to any population of organisms.
Two kinds of controls: Positive and Negative. Depending on the test/Instrument, Positive controls will have an indication or contain the specific substance that the test or instrument is used for. (Mostly for abnormal people according to the population.) Negative controls don't contain anything. (Mostly for normal people within the population.) --
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
Technically, eugenics is the use of any practice intended to specifically affect the genetic makeup of the population. Today the term is generally considered to be associated with unpleasant or reprehensible aspects of population control. One example is Nazi Germany's attempts to "purify" the human race by ridding the world of races that they believed to be deficient. Another is the use of sterilization and abortion to reduce the population of blacks in America. This was a founding principle of Planned Parenthood's Margaret Sanger.
a. Climate, weather (including droughts and floods), and fires can cause massive mortality in local populations irrespective of their densities.b. Pesticide use, pollutant release, and over hunting and fishing by people can have similar effects.c. Some species have evolved means of limiting their losses, such as seasonally migrating to a better climate or entering a period of dormancy when conditions deteriorate.d. predators kill prey and help control population e. Unusual weather also helps to control species like hurricanes, forest fires, ect.
Rapid population growth is influenced by a number of factors. The higher the population grows, the more pollution the environment will experience due to the increased level of human activities.
