The answer to this question would be osteoporosis.
The excessive loss of bone volume will result in multiple small holes formed in the bone. This condition called osteoporosis because the bone/osteo have small hole (porous). This will make the bone weaken and at risk of developing a fracture. Osteoporosis is commonly found in elder patient, especially in the postmenopausal woman.
Xerophytes are plants that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.
