Artificial pacemakers treat irregular heart rates and rhythms. Several conditions may be treated by an artificial pacemaker, such as bradyarrhythmias (slow heart rhythms), syncope (fainting spells), congestive heart failure (the heart pumps insufficiently which results to failure in maintaining blood flow), and hypertrophic cardiomyopathy (the heart becomes thick without a cause which results to failure in pumping blood effectively).
I believe it would be A. because that is the muscle that regulates the heart pumping. This would happen because the pacemaker is taking over and it now has no purpose.
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Each avocado fruit contains one large seed. Each tangerine fruit contains a dozen seeds or more. Because the tan- gerine tree produces more seeds per fruit, it has a higher biotic potential than the avocado tree.
