At near 0% R.H., between 20 and 40 degrees C the rate of body water loss gradually increased; on the other hand, the insects gained weight in an atmosphere close to saturation.

Webexpected to describe structural or functional adaptations that affect transpiration in a desert environment. Sample: 3A Score: 10 The response earned the maximum of 7 points in part (a): a point for an explanation of the mechanism of transpiration, and a point each for the discussion of stomata and tracheids and their role in the process. WebOne way that human activities can contribute to drought is through water mismanagement. This includes overuse of water resources, inefficient irrigation practices, and poor management of reservoirs and other water storage facilities. When these factors are combined with a lack of rainfall, it can lead to severe drought conditions.
