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.
Domain. The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function work, and will output real y-values.When finding the domain, remember: 1  The denominator (bottom) of a fraction cannot be zero. 2  The number under a square root sign must be positive in this work.ow to find the range. 1  The range of a function is the spread of possible y-values (minimum y-value to maximum y-value). 2  Substitute different x-values into the expression for y to see what is happening. 3  Make sure you look for minimum and maximum values of y. 4  Draw a sketch!
