What is Arndt-Schultz law?
[The Arndt-Shultz Law is very well described, with history and examples, by Dr. Rajneesh Kumar Sharma on http://www.similima.com/thesis32.html. Additional data is provided by Dr. A. B. Ram Jyothis on http://www.homoeotimes.com/archive/autramjothy.htm.] The Arndt-Shultz Law summarizes experiments which measure the physiological response of a living organism to a stimulus. It says a small amount of a chemical or electrical or laser or other stimulus will increase physiological activity, a large amount of the same stimulus will kill cells of the organism, and an intermediate amount will inhibit physiological activity. In brief: the physiological response reverses direction when the stimulus changes from small (weak) to large (strong), and vice-versa. An example of the Arndt-Shultz Law in action is the 1944 observation that a large dose of penicillin will kill a Staphylococcus infection, while a small dose will stimulate its growth. The Arndt-Schultz Law applies only where there is a dose-dependent reversal of the physiological effect on an organism, from beneficial to harmful, or vice-versa. In the case of Vitamin C, the reversal has occurred by the time the dose causes bowel intolerance. In the case of radiation in the environment from cosmic rays or nuclear fission or from decay of radioactive materials, in the development of protective standards, it was assumed by the U.S. Environmental Protection Agency and the U.S. Atomic Energy Commission that zero radiation is the only beneficial level of radiation. This assumption is contrary to the evidences that support the Arndt-Schultz Law. Submitted by David Langford, 18 March 2008.
What is the scientific maintenance of a stable internal environment?
Homeostasis is basically biological term also used in medical field . It is defined as maintenance of internal conditions constant or nearly constant . It includes three basic processes .1 : Osmoregulation. It is keeping balance of water and electrolytes in body which occurs with help of kidneys which are major osmoregulatory organs . If a person consumes more salts , it results in increased thirst which , increased water usage and production and elimination of extra salt to maintain osmotic pressure of body .2 : Thermoregulation . It is controlling body temperature by sweat , perspiration , thermogenesis , basking , vasodilation , vasoconstriction and other processes .3 : Excretion . it is elimination of wastes via excrtory organs as urinary system .
What is an observable reaction?
its a response
What is the definition of graded drug response to chloroquine?
The intensity of effect increases with the dose or concentration of drug is termed a Graded response
Where are the enzymes for electron transport located in bacteria if they don't have internal membranes?
Incorrect: Some bacteria do not have an electron transport chain and just glycolysis. If they do have an electron transport chain, then it would take place in the mitochondria.User response: Actually bacteria do not have a mitochondrium. Their electron transport chain is located inside their cytoplasmic membrane.

A change in an organism's environment that causes the organism to react is called?
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.
What is kenisis?
)Movement or activity of an organism in response to a stimulus such as light.
What Must Happen to Cause A Response in an Organism?
Something must change in the internal or external environment of the organism. This change can be physical or chemical and will result in a response from the organism. The scientific name for these changes are stimuli (singular = stimulus), examples of which are touching a hot surface, being scared, exercising and drugs. Hope this helps
Is signal to which an organism responds?
One of the things that making an organism alive is its' response to stimuli. This can be internal or external.
Is a signal to which an organism respond?

Is Adaptive response is the accommodation of an individual organism to its environment?
True
The ability of an organism to change in response to changes in the environment is?
adaptation
Which of these occurs when an organism responds to external or internal stimuli?
Anything in an organism's external environment that causes the organism to react is a stimulus. a reaciton to a stimulus is a response. The ability to respond to stimuli in the environment is an important characteristic of living things
What is Internal adaptation definition?
Internal adaptation refers to an organism's ability to adjust its internal systems in response to changes in its environment, ensuring survival and maintaining stability. This process involves physiological, behavioral, and genetic mechanisms that help the organism cope with various stressors and challenges. Internal adaptation plays a crucial role in enabling organisms to thrive and evolve in their ecosystems.
What is any change in the environment that causes a response in the organism is called?
stimulus
Is a signal to which organism responds?
One of the things that making an organism alive is its' response to stimuli. This can be internal or external.
