Which of the following factors would increase the rate of chemical reactions?

A. Organization:
Refers to the structured arrangement of parts from chemical to system level, not interaction with the environment.
B. Responsiveness:
Responsiveness is the ability to sense changes in the environment and react appropriately to maintain balance (homeostasis).
C. Growth and Development:
Refers to increase in size and complexity over time, not directly about environmental interaction.
D. Metabolism:
Involves internal chemical reactions but not necessarily interaction with external stimuli.
E. Waste Disposal:
A bodily process to remove waste, not primarily about environmental response.

A. anaphase – sister chromatids are pulled to separate ends of the cell: During anaphase, sister chromatids separate and move to opposite poles.
B. metaphase – chromosomes line up at the center of the cell: In metaphase, chromosomes align at the metaphase plate.
C. telophase – nuclear envelope is breaking down; chromosomes are condensing: In telophase, the nuclear envelope is reforming, and chromosomes are de-condensing into chromatin. The description given fits prophase, not telophase.
D. interphase – cell is going about its daily business, at the end DNA is duplicated and starts condensing: During interphase, the cell grows and replicates DNA in preparation for mitosis.
