The purpose of this biology lab was to measure the oxygen consumption during seed germination as evidence of the rate of cellular respiration. both germinating and non-germinating peas at different temperatures were used. glass beads placed in one respirometer served as the control.
considering the chemical reaction for cellular respiration, what must be included in the respirometer containing the germinating seeds?
a) oxygen
b) boiled water
c) oxygen and water
d) warm water and light

C) Oxygen and water

Explanation:

In cellular respiration chemical reactions, the reactants are glucose and oxygen.

In the provided reactants, there is no oxygen provided, hence, we need oxygen for the reaction to occur.

Since we are preparing to measure oxygen consumption during germination, water has to be there for germination to take place, hence our option includes water.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
