Hey guys i just wanted to know if any of you knew what the use of knowing the freezing point of water could be

i have to report this, it doesn't relate to biology

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

i believe your answer would be c.. : )
