A cladogram can help determine the relationship between species.
Prophase is the first stage of cell division, during which the genetic material condenses into chromosomes, the nuclear envelope breaks down, and the mitotic apparatus forms.
During prophase, the first stage of cell division in both mitosis and meiosis, several important events occur. Initially, the genetic material within the nucleus, which usually exists in a loose, unorganized state, condenses into visible and distinct chromosomes. Each chromosome replicates into two identical sister chromatids, bound together by a structure called a centromere.
As prophase progresses, the nuclear envelope begins to break down, and the nucleolus disappears. In the cytoplasm, specialized structures known as centrioles start to move towards opposite ends of the cell, forming a structure known as the mitotic (or spindle) apparatus, which will aid in the separation of the sister chromatids in later stages.
In essence, what happensduring prophase is the preparation of the cell for subsequent stages of cell division, by organizing its genetic material and forming necessary structures.

How does the structure of the mitochondria affect its function?
Answer:The mitochondrial structure affects its function because in its inner membrane, the cristae (folds) allow for more surface area which increases the amount of ATP that can be produced by the mitochondria.
Explanation: The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle.
