Noncontinuous ranges
A group of cells that touch each other and form a rectangle is called a range. These selected cells are adjacent to each other.
There is no such thing as a non-contiguous range. A range is a group of cells that are together in a rectangular block. Non-contiguous refers to cells that are not touching. So you can have more than one range which do not touch, so what you have are non-contiguous ranges. It is possible to select non-contiguous ranges by first selecting one range and then while holding the Ctrl key, select other ranges.
A change in the structure of cells and their orientation to each other is called anaplasia.
synapses.
Sex cells are also called gametes. Each has 23 chromosomes or half the number of other cells.

Cells recognize each other through glycoproteins. This is important because cells need to recognize each other in order to function correctly and control the health of your body.
A range can only be cells that are adjacent and in a rectangular shape. It is possible to select non-adjacent cells but this would not be regarded as a range. Each would be a separate range. So usually non-adjacent ranges will have gaps between them, although it is possible to have cells from to separate ranges right beside each other. You will know them by their boundaries around them.
Adjacent cells are cells that are together, and do not have other cells between each other. A cell beside another one are together called adjacent cells, as are cells that are above or below each other and touching. So A1 and A2 are adjacent cells, as are B1 and C1. A1 and C1 are not adjacent cells as B1 is between them. A1, B1 and C1 would be adjacent cells.
Cells that live as a connected group but do not depend on each other for survival are called colonial organisms.
in meisosis, cells formed are different from each other. in mitosis the daughter cells are identical.
They are all copies of each other.
