Answer:
Survival depends on interaction of many factors, which can vary greatly. For each factor a given species has a range of conditions. If environmental conditions exceed upper or lower limit of tolerance, death can result.
Explanation:
This is the Shelford's law of Tolerance.
This law states that the success of distribution of an organism can be controlled by some factors like topographic, climate, and biological requirements of plants and animals, in which their levels exceed the higher or lower limits of tolerance of the organism.
This was a law proposed by V. E. Shelford in 1911.
While females have a second X-chromosome that masks the X-linked recessive allele, males do not, but instead have a Y-chromosome which does not represent the same alleles as the X-chromosomes, resulting in not being able to mask the X-linked recessive allele.

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.
