Find the heat required to convert oxygen into 1 mole of ozone at 298K and 1 atm pressure from the following:

3 O2 + 4 B → 2 B2O3 ΔHo = −1264 kJ/mol B2O3

O3 + 2 B → B2O3 ΔHo = −1406 kJ/mol B2O3

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
