Answer 1

Answer: Hypothetico detective reasoning ( Because according to this scientific inquiry proceeds by formulating a hypothesis in a form that can be falsifiable, using a test on observable data where the outcome is not yet known.)

Answer: Squamous ( Squamous is flat shaped cells which covers the skin)

Answer:Osmolarity and diffusion. ( Osmolarity is the number of particles in the solute where as diffusion means flow of fluid i.e. into solute.)

Answer: Spinal and pelvic anatomy.
