COVID-19 tends to attach to cells in the respiratory tract and cause a lot of inflammation…especially in the cells that form the respiratory membrane. What are the layers of that respiratory membrane? Explain how a thickened respiratory membrane will interfere with gas exchange.

Trace the path of the glucose from a piece of bread from your mouth to absorption in the 1st segment of the organ where most absorption occurs….and then to your inferior vena cava. 

The respiratory center that is the primary generator of respiratory rhythm is the:

Select ALL that could happen to glucose when it enters a cell

Match the stages of cellular respiration with the correct sequence (i.e. first stage = 1)

Balance the equation below by placing the correct coefficients in the blanks. Your response should list the coefficients in order from left to right, separated only by commas; no spaces. If no coefficient belongs in a blank, represent it with a “1”. For example the equation 2 H2O →  2 H2 +O2 would be represented as 2,2,1. ____Cr + ____H2(SO4)  →  ____Cr2(SO4)3 + ____H2  

Which of the following choices best classifies the following reaction:Mg(SO3)  MgO+SO2 a. combination b. single replacement c. decomposition d. double replacement  e. redox f.  nonredox         

Which of the following compounds would be classified as molecular? KCl Cl2O  CaCl2 NaCl
