A plant biologist has been carrying out a long-term study of local buckwheat (chaparral plant) in southern California She has 20 years of data showing that a Buckwheat has a variable average leaf size of 4 cm, with some plants having larger leaves of up to 7 cm in width and some plants having smaller leaves, as small as 1 cm in width. She has noticed that over the last 5 years of drought, the average leaf width of buckwheat has decreased to 2.2 cm width. a. Tell me which type of selection is taking place?

b. Explain how you know?

c. Draw a line graph representing the population over the 15 years and the population after selection.

d. On a new graph like the one above, what would the population look like if there was disruptive selection?​

Please answer all the questions.

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
