You are part of the research group that hypothesized that relative humidity played a role in the transpiration differences. what additional evidence might you provide to support your hypothesis? a) population a has a high water potential and loss due to transpiration because of the increased humidity. b) population b has less water loss due to transpiration due to less crowding, less shading and an increase in humidity. c) population b shows an increased loss of water through transpiration because the environmental conditions are windier and less humid. d) population a has a low water potential and loss due to transpiration because more crowded conditions result in lower humidity and less shading.
