in a freshwater lake, a population of bony fish called the stickleback were studied over several decades. the presence of armor plating over the bodies of the males was noted. the data is shown below. what explains the trend shown in the data for the freshwater sticklebacks?
a) armor-plating offered a protection from predation, therefore the presence of armor-plating increased in frequency.
b) partially plated males were the preferred mating partner with female sticklebacks, causing an increase in partial armor frequency.
c) armor-plated males were more efficient at migrating to salt water areas for reproduction, resulting in armor-plating increasing in frequency.
d) armor-plated males were slower at acquiring food compared to the non-armored phenotypes, resulting in non-armored males to increase in frequency.

This map shows how climate change might affect precipitation patterns in the great plains of the united states by the end of this century. brown shoes a decrease in percipitation, and blue shows an increase. the maps differ based on the predictive levels of green house emissions. the maps shows that northern area should get a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels. southern areas show a. more pracipations regardless of emmissions b. less pracipation, regardless of emmissions levels c. more precipitation, but only when emission levels. to use these maps to prepare for natural disasters in the great plains, scientist need to ask? a. how many tons of emissions were used at the basis of the map. b. which types of fossil fuels are used in the great plains c. if you think the above is wrong it's probly c the question is cut off
