The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.

It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>
The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:
- Type 1: An increase in consumption
- Type 2: A decrease in consumption
- Type 3: Decreased consumption, followed by a quick increase.
The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
