As the stimulus intensity increases, the graded muscle response also increases in strength. This phenomenon is known as the principle of recruitment, where motor units are activated in a progressive manner based on the intensity of the stimulus. This allows for fine control over muscle force output.

What happens when stimulus gets stronger?
When a stimulus gets stronger, it can trigger a larger response in the organism. This can lead to heightened physiological reactions, increased sensitivity, and potentially a more pronounced behavioral response. Stronger stimuli can also improve learning and memory retention in some cases.
What happens to the light intensity as the magnification is increased?
As magnification increases, the light intensity typically decreases because the same amount of light is spread over a larger area. This reduction in light intensity can sometimes result in a dimmer image with more magnification.
What happens as a result of an increase in the intensity of?
An increase in the intensity of exercise leads to a higher demand for energy. This can result in increased heart rate, respiration, and blood flow to deliver oxygen and nutrients to muscles. Additionally, it can lead to a greater production of waste products like lactic acid.
What happens to the light intensity as the magnification is increased on May microscope?
As magnification increases on a microscope, light intensity typically decreases. This is because a higher magnification spreads the available light over a larger area, resulting in a lower intensity at any given point. To compensate for this, microscopes may have adjustable light sources or additional features to enhance visibility at higher magnifications.
What happens to a wavelength when the amplitude and frequency are both increased?
When the amplitude and frequency of a wave are both increased, the wavelength remains constant. Amplitude affects the intensity or loudness of the wave, while frequency determines the pitch. Therefore, changing the amplitude and frequency does not alter the wavelength of the wave.
How does the brain perceive the intensity of a stimulus?
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.
What happens when stimulus gets stronger?
When a stimulus gets stronger, it can trigger a larger response in the organism. This can lead to heightened physiological reactions, increased sensitivity, and potentially a more pronounced behavioral response. Stronger stimuli can also improve learning and memory retention in some cases.
How does a neutral stimulus become a conditioned stimulus?
A neutral stimulus becomes a conditioned stimulus through a process called classical conditioning. This happens when the neutral stimulus is paired consistently with an unconditioned stimulus that naturally elicits a response. Over time, the neutral stimulus begins to evoke the same response as the unconditioned stimulus, becoming a conditioned stimulus.
What is the difference between a positive and negative response in biology?
A positive response is when a response happens to a stimuli, and this response causes more of the stimuli to happen. A negative response is when a response happens because of a stimuli, and the response stops the continuation of the stimuli.
How are a stimulus and a response related?
They are directly related. Homeostasis is an environments ability to maintain stbility in a regular cycle, but when something new is introduced, the environment is able to respond to a new occurance, or stimulus, and responds in order to survive and return to maintaining a normal cycle. Without response to a new stimulus, environments would be unable to maintain homeostasis and would die out!
What the difference between reaction and response?
A reaction is what happens to the body when a stimulus is applied, a response is what happens next; i.e a stimulus illicits a reaction which illicits a respose. For example, glucose in the blood (a stimulus) causes the pancreas to release insulin (a reaction), which in turn causes the cells to take up glucose from the blood (a response).
How can the conditioned response become extinct?
A conditioned response can become extinct by reverse conditioning. That is, if a dog has been conditioned to drool when he hears a bell, he can be conditioned not to drool when he hears the bell.The conditioned response in psychology may become extinct when the withdrawl of reinforcement happens.
Identify and describe how an organism could respond to an external stimulus and describe a response to an internal stimulus?
An example of an external stimulus is a painful prick (and any other stimulus that happens OUT side the organism ). The organism could respond by pulling away from the pain caused by the stimuli. An example of an internal stimulus is the feeling of hunger or thirst (or any other stimulus that happens IN side the organism). The organism could respond by eating or drinking. a behavior
What happens to the light intensity as the magnification is increased?
As magnification increases, the light intensity typically decreases because the same amount of light is spread over a larger area. This reduction in light intensity can sometimes result in a dimmer image with more magnification.
What happens after the spinal cord makes a decision in a reflex?
There are no "decisions" involved in a reflex. Generally the response is to trigger whatever motor nerves move the affected area away from the stimulus.
What does s stand for and what occurs in this stage?
In psychology, the "S" stands for "stimulus" and this stage involves the presentation of a stimulus to elicit a response from an organism, typically in the context of classical conditioning. The stimulus can be anything that triggers a reaction in an individual.
What happens to the intensity of a bright fringe when the wavelength of the light is increased?
It decreases. This is because the same amount of energy is distributed over a larger area (wavelength increases, so fringe spacing also increases). Energy per unit area decreases and this is why intensity decreases.
