The gap between two neurons across which nerve impulses pass is called: MCQ with Answer and Explanation

Explanation:
Edward Jenner is considered the father of immunology for pioneering the concept of vaccination by developing the smallpox vaccine. Alexander Fleming discovered the first antibiotic, penicillin, from the fungus Penicillium notatum in 1928. Louis Pasteur made monumental contributions to microbiology and vaccination, but the structure of DNA was discovered by James Watson and Francis Crick in 1953. Thus, statements 1 and 2 are correct.

Explanation:
Innate immunity is the non-specific, inborn defense mechanism present from birth, providing immediate but general protection against pathogens. Acquired (adaptive) immunity is highly specific, targeting particular antigens and developing memory. The secondary immune response, occurring upon re-exposure to the same antigen, is much faster, stronger, and more prolonged than the primary response due to the presence of memory cells. Thus, statements 1 and 2 are correct.

Explanation:
Apiology is the specific branch of zoology dedicated to the scientific study of bees, including their biology, ecology, and behavior. Malacology studies mollusks, myrmecology focuses on ants, and entomology is the broader study of all insects. Exam tip: Remember 'Api' relates to Apis, the genus of honeybees.
