The type of muscle found in the walls of the digestive tract is: MCQ with Answer and Explanation

Explanation:
Mitosis produces two genetically identical diploid daughter cells (clones) essential for growth, repair, and asexual reproduction. Meiosis involves pairing (synapsis) and crossing over during prophase I, and produces four genetically diverse haploid cells (gametes). The conservation of chromosome number and genetic identity is a hallmark of mitosis.

Explanation:
The cardiac conduction system ensures coordinated heartbeats. The sinoatrial (SA) node generates the electrical impulse, acting as the natural pacemaker. The impulse reaches the atrioventricular (AV) node, which delays it slightly to allow the atria to fully contract and empty into the ventricles. The impulse then travels down the Bundle of His to the Purkinje fibers, which rapidly distribute it throughout the ventricular myocardium, causing ventricular contraction. All statements are correct.

Explanation:
Measles (rubeola) is a highly contagious viral disease caused by the measles virus (a paramyxovirus), characterized by fever, cough, and a distinctive red rash. Anthrax is bacterial (Bacillus anthracis), malaria is protozoan, cholera is bacterial. Measles can be prevented by the MMR vaccine. It is a leading cause of child mortality in unvaccinated populations.
