In humans, each cell nucleus contains 23 pairs of chromosomes a total of 46 chromosomes. The first 22 pairs are called autosomes which look exactly the same in both males and females. The 23rd pair of chromosomes is called an allosome. These sex chromosomes differ between males and females. Females have two copies of the X chromosome, while males have one X chromosome and one Y chromosome.
Range refers to the y-axis. Domain refers to the x-axis. Range refers to the y-axis. Domain refers to the x-axis.
A function represented by the mapping above in which each element of the range is paired with exactly one element of the domain is called one-to-one mapping. In the mapping, the second element of the range associates with more than one element in the domain.xample: Draw a mapping diagram for the function f (x) = 2 x 2 + 3. First choose some elements from the domain. Then find the corresponding y-values (range) for the chosen x-values. The domain of the function is all real numbers. Let x = â1, 0, 1, 2, and 3.
