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 shows a decrease in precipitation, and blue shows an increase. The maps differ based on the predicted levels of greenhouse gas emissions. The maps show that northern areas should get . Southern areas will likely get . To use these maps to prepare for natural disasters in the Great Plains, scientists need to ask, ?

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
