Be sure to include: the specific reason for use the alleged results on improving performance how it works how it affect homeostasis and improves performance any side-effects of this substance
Neurons and Reflexes 1. Describe the function of the: a) dendrite b) axon c) cell body d) myelin sheath e) nodes of Ranvier f) Schwann cells g) motor neuron, interneuron and sensory neuron 2. List some simple reflexes. Explain why babies are born with simple reflexes. What are they and why are they necessary. 3. Explain why you only feel pain after a few seconds when you touch something very hot but you have already pulled your hand away. 4. What part of the brain receives sensory information? What part of the brain directs you to move your hand away? 5. In your own words describe how the axon fires.
Mutations Here is your template DNA strand: CTT TTA TAG TAG ATA CCA CAA AGG 1. Write out the complementary mRNA that matches the DNA above. 2. Write the anticodons and the amino acid sequence. 3. Change the nucleotide in position #15 to C. 4. What type of mutation is this? 5. Repeat steps 1 & 2. 6. How has this change affected the amino acid sequence? 7. Now remove nucleotides 13 through 15. 8. Repeat steps 1 & 2. 9. What type of mutation is this? 0. Do all mutations result in a change in the amino acid sequence? 1. Are all mutations considered bad? 2. The above sequence codes for a genetic disorder called cystic fibrosis (CF). 3. When A is changed to G in position #15, the person does not have CF. When T is changed to C in position #14, the person has the disorder. How could this have originated?
