When do copied chromosomes divide?
The paired chromosomes separate at the kinetochores and move to opposite sides of the cell during anaphase.
What two paired cell structures are copied before mitosis begins?
Chromosomes are copied in the form of sister chromatids during S-phase of the cell cycle, which are then separated during mitosis. The centrioles also duplicate before mitosis begins to ensure proper formation of the mitotic spindle and accurate segregation of chromosomes.
How a cells chromosome change as a cell prepares to divide?
the chromosomes are replicated (copied) and are compacted into dense visible structures
Cell structures that carry the genetic material that is copied and passed from generation to generation of cells?
Cell structures that carry the genetic material that is copied and passed from generation to generation of cells are called chromosomes. Spindles are cell structures composed of microtubule fibers.
What are three essential structures found in all cell types?
DNA, cytoplasm. cell membrane
What two types of structures deal with the movement of a cell?
Flagella and cilia
What is referencing in terms of Microsoft Excel?
Referencing is basically referring to another cell in a formula. There are 3 types of cell addressing or cell referencing mechanisms in Excel. They are relative, mixed and absolute. Relative is typing the address as it is in the cell. When the formula is copied, the reference in subsequent formula changes accordingly. With absolute and mixed referencing you are preventing the cell reference from partially or fully changing in the formula when it is copied. This is done by putting a dollar before the cell's column or row, for mixed referencing, and before both parts for absolute referencing. A1 - Relative: The cell address will change when copied in a formula. $A1 - Mixed: The cell address column will not change when copied in a formula. A$1 - Mixed: The cell address row will not change when copied in a formula. $A$1 - Absolute: The cell address will not change when copied in a formula.
Which organism is correctly paired with the structures it uses for the excretion of nitrogenous wastes and carbon dioxide?
Fish are correctly paired with gills for the excretion of nitrogenous wastes and carbon dioxide. Gills are specialized structures that allow fish to exchange these waste products with the surrounding water during respiration.
How often is DNA?
DNA is copied every time a cell divides. Different types of cells divide at different rates.
Does the animal and plant cell have the same wall?
No, they are different types. They have different structures.
Structures that have a specific function in a cell are called what?
There are different types of these, they are called organelles.
What is a cell being copied?
The source cell or the active cell.
