In the context of the skin senses, when warm and cold receptors that are close to each other in the skin are stimulated simultaneously, a person experiences the sensation of hotness coldness hotness and coldness neither hotness nor coldness

The correct answer is option A " hotness"

The receptors either hot or cold receptor produces electrical signals whenever there is an external stimulus in the form of temperature change.  

In the case of thermo receptors which are activated by heat condition, the rate of signaling increases which in turn produces warm feeling while in case of thermo receptors which are activated by cold condition, the rate of signal reduces and the rate of firing increase and this stimulates cold feeling. Thus, when the two receptors are stimulated simultaneously, the fast signaling due to activation by heat has a faster rate of increasing the signal as compared to the activation by cold.

good lesson

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
