and to show an example of a disaster that happened. Both of these goals will be reached by presenting a power point. Through the power point I pointed out the different categories of bioterrorism‚ the harmful effects that can happen‚ and knowing the basics of bioterrorism like the definition and categories. I also presented some examples of bioterrorism agents and how they can spread and where they are found. To educate the class about disasters I had slides showing different examples of the two different

other • Enable specific communication • Enable rapid communication • Enable both short and long-term responses. State that cells need to communicate with each other by a process called cell signalling. State that neuronal and hormonal systems are examples of cell signalling. Define the terms negative feedback‚ positive feedback and homeostasis. Negative feedback- A process in which any change in a parameter brings about the reversal of that change so that the parameter is kept fairly constant.
