Answer:
Transporting Electrons
As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions (from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space. Electron transport in a mitochondrion is shown in Figure below.

It is a rare genetic mutation that both the maternal and paternal partners have to be at least a carrier for the albinism gene.
Question:
Trudy made this Venn diagram comparing interphase and cytokinesis.
Which statement belongs in the region marked X? (image attached)
Answer options:
- Is the longest stage
- DNA is copied
- The number of nuclei doubles
- The number of cells doubles
Answer:
- The number of cells doubles
Explanation:
Cytokinesis describes the splitting of the cytoplasm after mitosis. During interphase, the DNA is replicated. During mitosis, the DNA condenses into chromosomes, and the chromosomes are aligned and separated to opposite ends of the cell. During cytokinesis, the cell separates into two daughter cells.
