Topics for biology project?

Healing processes of the skin. I personally thinks it's really intriguing as it pertains to everyone, and every ones also bound to learn something new, plus look down at their arm a few hundred times during your presentation!

Wow, that's quite broad. You could talk about disease -- bacterial, viral, prion, genetic, pharmaceuticals, aging physics -- biomechanics, thermodynamics genetics -- inheritance, mutation, evolution, cancer, taxonomy, gene expression, epigenetics systems -- nervous, cardiovascular, immune, musculoskeletal, integumentary, digestive, excretory, endocrine, reproductive morphology -- embryonic development, stem cells toxicology cellular biology -- respiration, photosynthesis, mitosis, protein synthesis and conformation, osmosis, endo- and exocytosis, apoptosis, cellular locomotion ecology -- symbiosis, endosimbiont theory, population control fitness and athletics biotechnology -- genetic sequencing, vaccines, etc. psychology and neurobiology surgical techniques, medical imaging ~ x-ray, pet, radioisotopes, mri did that give you any ideas?
