When we think about internal stability we first think of animals. But all organisms must maintain internal stability or homeostasis. When plants are under water stress they respond in a way to conserve the internal water. How would leafy plants respond to temporary water stress? (A)Develop a thick waxy cuticle, (B)Leaves wilt and photosynthesis temporarily stops, (C)Stomata stay open to help draw water up from the roots of the plants, (D) Stomata open less frequently to restrict transpiration and conserve water.

In water stres stomata open less frequently to restrict transpiration and conserve water.

Explanation:

In response to a water deficit stress, water transport systems across membranes function to control turgor pressure changes in guard cells and stimulate stomatal closure.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
