Which best describes the relationship between a parent cell and daughter cells in mitosis?(1 point)
Responses

Parent cells share new types of DNA to daughter cells to ensure diversity.
Parent cells share new types of DNA to daughter cells to ensure diversity.

Parent cells divide several times to ensure daughter cells have half of the parent cell’s DNA.
Parent cells divide several times to ensure daughter cells have half of the parent cell’s DNA.

Parent cells duplicate their DNA, then divide into daughter cells that are identical.
Parent cells duplicate their DNA, then divide into daughter cells that are identical.

Parent cells divide randomly, and daughter cells have varying amounts of DNA.

The statement that best describes the relationship between a parent cell and daughter cells in mitosis is: Parent cells duplicate their DNA, then divide into daughter cells that are identical.

Without seeing the image, I can’t determine exactly which process is being shown. However, based on your earlier questions, if the image depicts the division of cells or the process of cells splitting, it is likely mitosis. If it illustrates how genes are being turned into proteins, it could be gene expression. For processes related to cells becoming specialized, it would be cell differentiation. Lastly, if it shows aging or the gradual deterioration of functions, it would refer to senescence.

If you provide more context or details about the image, I can assist you better!
