Mitosis is a process of cell division that occurs in eukaryotic cells, which include organisms such as phytoplankton, protozoans, and zooplankton. However, bacteria are prokaryotic cells and do not undergo mitosis. Instead, they typically reproduce by binary fission.
Therefore, the correct response is:
**bacteria**
Therefore, the correct response is:
**bacteria**

Which best describes the relationship between a parent cell and daughter cells in mitosis?(1 point)
Responses
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 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 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 randomly, and daughter cells have varying amounts of DNA

The best description of 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.**
This accurately reflects the process of mitosis, where a single parent cell replicates its DNA and divides to produce two genetically identical daughter cells.
**Parent cells duplicate their DNA, then divide into daughter cells that are identical.**
This accurately reflects the process of mitosis, where a single parent cell replicates its DNA and divides to produce two genetically identical daughter cells.

The correct order of the steps of gene expression is:
**DNA transcribed → RNA spliced → mRNA translated → ribosomes make proteins.**
In this process:
1. **DNA transcribed:** The DNA sequence of a gene is transcribed into pre-mRNA.
2. **RNA spliced:** The pre-mRNA undergoes splicing to remove introns, resulting in mature mRNA.
3. **mRNA translated:** The mature mRNA is then translated into a protein at the ribosome.
This accurately reflects the steps involved in gene expression.

The statement that best explains a potential benefit of being a naturally polyploid organism, such as a banana or an amphibian, is:
**Natural polyploidy may protect a cell from harmful mutations.**
Polyploidy can provide a buffer against harmful mutations because having multiple copies of genes can help ensure that if one copy is mutated, others may still function normally. This can contribute to increased genetic diversity and resilience.
