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.

Answer:
DNA
Explanation:
If this is sexual reproduction, there needs to be 2 parents who have completely different DNA. Which give you different traits and genes. However if this is asexual reproduction, the new organism will look exactly like the parent(s).
O Gravity attracts only larger objects toward one another.
O Gravity attracts larger objects only if they are close to
one another.
If the masses of the objects increase, then the force
between them also increases.
