Answer:
15 hours and 40 minutes
Explanation:
The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.
Interphase: 15 hours
Prophase: 20 minutes
Metaphase: 20 minutes
Cells are limited in size to maximize efficiency (accessing nutrients and getting rid of waste as well as decreasing the chances that information will become erred).
A cell with 2cm sides has a surface area of 2cm x 2cm x 6 = 24 cm^2
Volume would be 2cm x 2cm x 2cm = 8cm^3
Surface area : Volume = 24:8 or 3:1
A cell with a large volume will have more difficulty accessing nutrients and getting rid of waste quickly and transferring information that has no mistakes in it
Light is an example of an abiotic factor. its also a major energy source
