C is prophase because the nuclear envelope starts to disappear and the centrosomes divide
B is metaphase because chromosomes line up to form the equatorial plate
A is anaphase because the sister chromatids are separated
D is telophase because new nuclei form around the separated genetic material
Photosynthesis gives out oxygen and takes in carbon dioxide
Aerobic respiration uses the oxygen and gives out carbon dioxide
-Making a cycle
(Without the respiration the cell would die which would stop photosynthesis)
Hope this helps!!
Answer:
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
