According to Weber's law, the size of a just noticeable difference or difference is a constant proportion of the size of the initial stimulus.
Explanation: Weber’s law is a principle that describes that for two stimuli to be perceived as different, the stimuli should differ by a minimum constant percentage and not by a constant amount.
For example: in a noisy room it is required to shout in order to be heard in contrast a whisper can be heard in quiet room. For us to be aware consciously 50% of the time the minimum stimulation required for any stimuli.
The absolute threshold for difference between the two stimuli of any individual may vary and depends on the strength of the signal apart from the experience, alertness, expectation and motivation.
The individual’s difference threshold also known as just noticeable difference is the difference between two stimuli half of the time that we can distinguish.
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
Brainliest please? I need it to level up.
Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
