Biological oceanographers discuss biomass frequently. Just what is biomass?
a) The number of organisms produced in a given time
b) The total weight of protoplasm contained in a given organism
c) The total mass of all organisms
d) The total number of organisms within a given class
e) The total number of organisms within a given class divided by the total weight of those organisms
Question 2
How does the latent heat of evaporation (and its equivalent, the latent heat of condensation) moderate climate?
a) It retards the formation of ice, keeping the oceans warmer.
b) By absorbing energy on evaporation and releasing it on condensation, it keeps water cool when the air is hot and warm when the air is cool.
c) The endothermic reaction does not allow salt to build up past a certain concentration.
d) The latent heat helps generate winds, which help keep the oceans cool when the air is hot.
e) It gives water a higher heat capacity, which allows it to stay cool when the air is warm and warm when the air is cool.
