Answer:

A. 17,100

Explanation:

The half life of carbon-14 is around 5,700 years. When the shell contains 50% of its original carbon-14, 5,700 years have passed. 25% means another 5,700 years have passed, meaning 11,400 years in total have passed. 12.5% means another 5,700 years have passed, meaning 17,100 years have passed in total.

evablogger [386]

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

What might happen if cytokinesis were omitted

Georgia [21]

Answer:

Explanation:

Cytokinesis is the process by which the cytoplasm splits, forming two daughter cells from one parental cell. It occurs towards the end of mitosis, after the DNA has been replicated. The process of mitosis generates a cell with two nuclei, and cytokinesis ensures that each daughter cell receives one nucleus.

Without the process of cytokinesis, the physical process of the production of two cells from one parental cell would not occur, so the cell would not divide into two daughter cells.
