If the average normal temperature decreases with altitude in the
troposphere is 6.5°c/km, calculate the approximate temperature
at 6 km if the surface temperature is 16°c. show your work below
(hint: it will be a negative number).

Describe the primary and secondary immune response in terms of speed and number of antibodies produced?

Photosynthesis uses co2 and cellular respiration produces co2. we call the point when the two processes are in balance--when there is no net production of co2--the compensation point. how might you limit one of the processes in order to achieve a compensation point?
