Across
  1. 3. transmission mechanism that involves direct touching
  2. 5. enzyme involved in breaking down fats
  3. 7. structure in plant that runs from a source to a sink and carries the products of photosynthesis
  4. 9. immune system that contains vasodilation
  5. 11. "coat" or covering that surrounds some invading pathogens for protection
  6. 15. part of the neuron that receives input
  7. 16. organisms that match their internal osmolarity to the environment
  8. 20. coat on the neuron that increases signal transmission
  9. 22. type of feedback that returns you to set point
  10. 24. organelle where proteins are made
  11. 25. high levels of this hormone are found in dehydrated people
  12. 26. neuron that carries information from receptors, and is pseudounipolar
  13. 27. immune response that involves B cells and antibodies

Down
  1. 1. signalling molecule used to pass messages between neurons
  2. 2. structural feature found in penguins for thermoregulation
  3. 4. a disease is this if it is caused by a parasite
  4. 6. some organisms produce this chemical defence mechanism to defend themselves
