Basis of classification

  • Reptilia = temporal fossa of cranium & their no.

  • Porifera = endoskeletal elements.

  • Coelentrata = development of zooids.

  • Platyhetminths = body shape, mouth position, habitat.

  • Annelida = organ of locomotton.

  • Arthropoda – Body apperdages, mode of resp & excretion.

  • Mollusca = foot & shell

  • Echinodermata = body shape, Madreporite position & kind of Larva.

  • Pisces = endoskeleton

  • Setrapoda = skin (ie. Amphibian, aves, reptiles & mammals)

  • Alges = type of pigmentation.

  • Protozoa = locomotory organelles.

  • σ = e (ne μ e + ng μ h)

  • Diffusion P -> N

  • Drift N -> P.

  • Thermal conductivity = Ag > Cu> Al> bross > steal > concrete > bricle > Glass> H2o > celoten > trans former oil > H2 > wood > manonite > rock > wool > O2 > air.

  • Thermos hasle – prevent radiation – silvering outer surface.

  • Prevent conduction / convection – no medium inside.

  • Kindling temperature – temperature above which substance catch fire.
