The factor that primarily determines how a cell will differentiate is **the genetic information encoded in the DNA**. While other factors such as the physical location of the cell in the body and environmental influences can play a role, the genetic information provides the fundamental instructions for a cell's development and specialization.

Multicellular organisms need to perform mitosis **to repair damaged tissues and enable growth**. Mitosis is the process by which a cell divides to produce two identical daughter cells, which is essential for growth, development, and healing in multicellular organisms.
Answered by GPT-4o mini
The organism that performs binary fission is **Bacteria**. Binary fission is a method of asexual reproduction in which a single organism divides into two identical offspring, commonly seen in prokaryotes like bacteria.

The purpose of checkpoints during the cell cycle is **to repair any damage to the DNA and ensure accurate replication**. Checkpoints monitor the integrity of the cell's genetic material and ensure that the cell is ready to proceed to the next phase of the cycle, which helps prevent errors that could lead to cell malfunction or disease.
Answered by GPT-4o mini
The reason the 2 daughter cells are genetically the same as the parent cell after mitosis is **because they receive identical sets of chromosomes**. During mitosis, the chromosomes are replicated and then equally divided between the two daughter cells, ensuring that each daughter cell has the same genetic information as the parent cell.
Answered by GPT-4o mini
The option that best defines stem cells is **stem cells are undifferentiated cells that can differentiate into specialized cell types**. Stem cells have the unique ability to develop into various types of cells in the body, making them crucial for growth, development, and tissue repair.
