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.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

d.  

there was a variety of food available on island x, but there were only large seeds and nuts on island y.
