Explanation:
a variable (often denoted by x ) whose variation does not depend on that of another.
If pea plant cells contain 14 chromosomes, a pea plant's gamete cell contains 7 chromosomes.
<h3>Describe chromosomes.</h3>
Chromosomes are a pair of thread-like structures that are found in cells.
Re genes and a person's personality are found on the chromosomes.
Meiosis causes the daughter cells to contain half of each chromosome.
<h3>What does a chromosome do primarily?</h3>
Chromosomes' primary role is to transport DNA, which is the building block of all genetic material. DNA contains the genetic instructions for a number of cellular processes. These activities are necessary for the organisms' development, maintenance, and procreation. Chromosomes are shielded by proteins like histones.

M stands for mitosis. This is where the cell actually partitions the two copies of the genetic material into the two daughter cells. After M phase completes, cell division occurs and two cells are left, and the cell cycle can begin again.
Answer:
B
Explanation:
During the Krebs cycle in the matrix of the mitochondria, H+ ions are usually pumped to the intermembrane space creating a proton-motive force. This potential difference is harness by ATP synthase to make ATPs as the H+ ions 'drain' back to the matrix of the mitochondria. As these H+ get to the matrix, they ultimately reduce oxygen to water. In this reaction, oxygen also acts as the ultimate electron acceptor in the Krebs cycle accepting 4 electrons from NADPH/ NADH (so these molecules can be recycled back as NAD+ and NADP+).
4H⁺ + O₂ + 4 ⁻e → 2H₂O
