What is the definition of diffusion in scientific terms?
Diffusion refers to the process by which molecules intermingle as a result of their Kineti energy of random motion
What is the definition of chemotropism and what exhibits it?
Movement or growth of an organism or part of an organism in response to a chemical stimulus.
What is a stimulus in science?
In science, the word stimulus is used to describe something that evokes a response or reaction from a living subject, whether it be a touch, a sound, etc. A few examples of stimulus: - bright light (affects sense organs and receptors) - physically touching the subject (external stimulus) - loud noise (affects sense organs and receptors)
What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
What are the types of cultural diffusion?
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
Stimulus Diffusion ?
The spread of an underlying principle
What type of diffusion is Economic development through international trade is an example of?
stimulus diffusion
Name three ways that culture can be spread Be specific?
Three ways that culture can be spread, including, Relocation diffusion, Expansion diffusion and stimulus diffusion.
What is the definition of maximal stimulus?
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
Do substances diffuse in response to a stimulus?
Yes agitation can affect the rate of diffusion.
What is the process of spreading new ideas called?
Diffusion is the process of spreading new ideas from culture to culture. Examples of diffusion include the use of cars and the smelting of iron. There are five main types of diffusion they are: Expansion diffusion, Relocation diffusion, Hierarchal diffusion, Congious diffusion and Stimulus diffusion.
What is the definition of hearth diffusion?
Hearth Diffusion is and idea or innovation that spreads outward.
What is the definition of a neutral stimulus?
Neutral stimulus is a stimulus which initially produces no specific response other than focusing attention. In classical conditioning
What is the definition of a submaximal stimulus?
Submaximal Stimulus results in complete contraction of some fibers. It causes contraction more than subminimal stimulus and less than maximal stimulus.
What is the definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.
What is the definition of contagious diffusion?
Contagious diffusion is a branch of expansion diffusion. It refers to a cultural trait spreading across a population like a disease.
