  • Coal mine workers dehydration by water & salt loss by prespiration.
  • In allergic condition, cortisols are used.
  • Thyroxin, Adrenaline & melamine tyrosine is common.
  • Prostatic secretion – alkaline.
  • Discoblastula in here.
  • Antifertilizin by spermatid or sperms.
  • Smallpox – eradicated from world.
  • Sperm – antifertilizier
  • Overm – fertilizier
  • Fe 3 + + red
  • Fe2 + - green
  • Low packing fraction = more stable.
  • Sandmeyere React – Cucl2

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 (i.e.. Amphibian, aves, reptiles & mammals)
  • Alges = type of pigmentation.
  • Protozoa = locomotory organelles.
  • = e (ne e + ng 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.
