The cell's chromosomes separate.
The contents of the cell divide.
The cell's DNA is replicated.
The cell prepares for mitosis.
12)At a point during a cell's development, it begins to differentiate. How does differentiation occur? *
10 points
Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport.
The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.
A developing cell's function is determined by the number of organelles that are contained in the cell.

7) When a body cell divides through the process of mitosis, the chromosomes in the daughter cells are identical to the chromosomes of the parent cell. This is because during mitosis, the parent cell's chromosomes replicate and then separate into two identical sets, each set going into one of the daughter cells. To get this answer, you can remember that mitosis is a type of cell division where the daughter cells are exact copies of the parent cell, and this includes the chromosomes.
8) Before a cell enters mitosis, the genetic information in that cell is duplicated. This is because in preparation for cell division, the DNA in the cell is replicated so that each daughter cell will receive a complete set of genetic information. To arrive at this answer, you need to know that DNA replication occurs before cell division and is an important step in ensuring that each cell receives the correct genetic information.
9) Mitosis is a phase in asexual reproduction that results in the formation of identical nuclei in the daughter cells. In asexual reproduction, only one parent is involved, and mitosis allows the parent cell to divide and produce genetically identical daughter cells. To determine the answer, you can recall that mitosis is a process of asexual reproduction, where the resulting daughter cells are genetically identical to each other and to the parent cell.
10) During the interphase stage of the cell cycle, I. DNA is replicated and III. The cell grows in size. Interphase is the longest phase of the cell cycle and is divided into three subphases: G1, S, and G2. During the S phase, DNA replication occurs, ensuring that each daughter cell will receive a complete set of genetic information. Additionally, during interphase, the cell also grows in size and carries out its normal functions. To determine the answer, you can remember the different subphases of interphase and the activities that occur during each subphase.
11) During the S phase of the cell cycle, the cell's DNA is replicated. This means that the genetic material in the cell is duplicated, creating two identical copies of each chromosome. The S phase is an important part of interphase, where the cell prepares for cell division by ensuring that each daughter cell will have a complete set of genetic information. To arrive at this answer, you can recall that DNA replication occurs during the S phase of interphase.
12) Differentiation occurs as certain genes are turned on and others are turned off, producing adult cells that are specialized. During development, cells become specialized to perform specific functions through a process called differentiation. This specialization is achieved by activating or deactivating specific genes within the cell, determining which proteins are produced and what functions the cell will perform. To determine the answer, you need to understand that differentiation occurs through changes in gene activation and inactivation, leading to specialization in cell function.
