Final answer:
In spreadsheet software, 'A1:A3' is the correct example of a range of cells. In biology, the term 'cells' can refer to immune cells or molecules like antigens, as seen in blood type determination.
Step-by-step explanation:
An example of a range of cells in spreadsheet software is D) A1:A3. In spreadsheet applications such as Microsoft Excel, a colon (:) is used to denote a range of cells, from the starting cell to the ending cell, inclusive. In this example, A1:A3 represents all cells in column A, from row 1 to row 3. This would include cells A1, A2, and A3.
In the context of biology, related to the immune system and blood types, the terms 'cells' and 'A1, B1' could be referring to specific types of immune cells or molecules like antigens or hormones. For example, in the ABO blood group system, antigens on the surface of red blood cells determine an individual's blood type - A, B, AB, or O. This is an instance of cellular communication and expression regulation.
