Answer 1

21. Lascaux and Altamira are famous for their elaborate cave paintings.

22. Dark skin of population near equator is due to the skin pigment melanin which acts like a natural sunscreen and hence protects them from the harmful effects of ultra violet rays which is quite high near the equator. Hence dark skin of populations near equator is because it protects from overexposure to ultraviolet radiations.

23. UV radiation rapidly depletes folate which plays a crucial role in neural tube development in embryos.

24. Disease causing organisms such as bacteria and viruses are called pathogens.
