1. An ectotherm are

  • monitors the factors that are controlled ie. temperature of the blood
  • organisms that are not able to use their own internal source of heat generated to maintain body core temperature. Their body core temperature fluctuates with the envornment
  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
  • organisms that are not able to use their own external source of heat generated to maintain body core temperature. Their body core temperature fluctuates with the envornment
  • organisms that are able to use their own internal source of heat generated to maintain body core temperature. Their body core temperature fluctuates with the envornment

2. Define homestasis

  • the maintainance of internal body envirnment in a constant stable state without external changes which may take place
  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
  • receptors which monitor change in the skin temperature in order to detect change in body core temperature
  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce

3. A neuronal system is

  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
  • a system which is a vital part of the bodys communication system. neurones are interconnected in order to send messages(AP) to the brain/other neurons in order to stimulate a responce
  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce

4. define effectors

  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
  • receives information in the form of signals from the receptors enabling efficient communication in order to carry out an action ii.e low secretion of insulin
  • a system which is a vital part of the bodys communication system. neurones are interconnected in order to send messages(AP) to the brain/other neurons in order to stimulate a responce

5. define perpherial temperature receptors

  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
  • receptors which monitor change in the skin temperature in order to detect change in body core temperature
  • type of communication system whereby one cell will release chemicals detected by the target cell, acts as a responce
