Answer:
<h2>The cells in a crosstab show summary data for the corresponding row and column, based on a measure and a summary function. The simplest crosstab is a frequency matrix, such as the following example, which shows the count of pets (measure) by gender (column) and species (row). Example of a simple crosstab</h2>

Answer:
.D. two daughter cells with twice the amount of DNA.
Mitosis is a multiplication division with the daughter cells having twice(diploid) the amount of DNA present in the parent cells that is 2n, The Chromosomes number doubles in the daughter cells , and therefore the DNA also doubles with each successful generation in the daughter cells. It is this ability to multiply the genetic components that makes Mitosis to be called multiplication division.
The parents and daughter cells are exactly similar.
Each daughter cell with its double genetic composition can also pass on to its own subsequent generation the genetic composition since its DNA and chromosomes . Thus enough amount can be passed to its own daughter cells too, which explains the need for double DNA inherited from the parents
