There’s no picture how do I know which one?
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.
The alteration in the protein structures can take place due to many reason. Once, the structure of the protein is altered, it cannot perform its function, as it cannot bind to the site for which it is designated.
Most of the biological processes use proteins in their completion. In case, the protein cannot perform its function, the metabolic process associated with that particular protein may stop and cause severe illness.
The heat can cause the denaturation of the proteins. The proteins are made up of amino acid sequences, the heat can break the peptide bond present between the amino acids present in protein, which can result in alteration of protein.
Hence, the correct answer is option (d). all of them are correct.
I don't know sorry
