IB Mathematics Standard Level Portfolio Assignment Task I Tide Modeling Kelvin Kwok In this modeling assignment‚ I will develop a model function for the relationship between time of day and the height of the tide. I will first show the data in a table form copied from the assignment sheet. Then I will use the data to construct a scatter graph of time against height‚ then I will develop a function that models the behavior noted in the graph analytically‚ and describe any variables‚ parameters

Thus‚ "freeze‚ flight‚ fight‚ or fright" may be a more complete and nuanced alternative to "fight or flight." [6] The hypothalamo-pituitary-adrenal axis Any demand made upon the body - whether physical or emotional‚ whether from internal or external causes‚ produces a nonspecific stimulus (a "stressor"). This is converted into nervous signals that may be carried by any of many different neural pathways
