Question

question 13
in the electron transport system, the final electron acceptor is
carbon dioxide.
water.
oxygen.
hydrogen ions.
question 14
normal mitosis results in
cells that are genetically identical to the parent cell.
cells that are haploid.
cells that are not genetically identical to the parent cell.
cells that are polyploidy.
question 15
which of the following phases is not correctly matched with its description?
metaphase - chromosomes align along the center of the cell
anaphase - mitosis is complete
prophase - chromatin condenses into chromosomes
teleophase - nuclear envelope reappears

Explanation:

• Question 13: In cellular respiration's electron - transport system, oxygen accepts electrons and combines with hydrogen ions to form water, making it the final electron acceptor.
• Question 14: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. It maintains the same chromosome number.
• Question 15: Mitosis is completed in the telophase. Anaphase is the stage where sister chromatids separate and move towards opposite poles of the cell.

Answer:

• Question 13: C. oxygen
• Question 14: A. cells that are genetically identical to the parent cell
• Question 15: B. anaphase - mitosis is complete
