In some, the leaves are needle-like and stomata are reduced in number and located in cavities on the epidermis. A layer of moist air builds up in the cavity. This reduces the humidity difference between the intercellular air spaces in the leaf and the immediate external environment thus reducing the rate of transpiration.
In some the epidermis of the leaves is multilayered and is covered with a thick waxy cuticle which reduces water loss through evaporation, e.g. oleander. The cuticle is normally shiny which helps to reflect solar radiation preventing the leaf from heating up rapidly.
Answer: As you've learned, some viruses are released when the host cell dies, and other viruses can leave infected cells by budding through the membrane without directly killing the cell.
I cant see the graph but the likely affect would be a unbalance to the food chain because animals that relied on the rabbits as a food source will go hungry.
