After adolescence, bones stop growing longer. They do, however, continue to grow. Describe how bones remodel or undergo repair
What will be an ideal response?
During remodeling, osteoclasts cut through mature bone tissue, dissolving the hydroxyapatite and digesting the matrix. The result is a release of calcium and phosphate ions into the blood. The areas where bone has been removed attract new osteoblasts that produce new matrix and new hydroxyapatite.

Rice is a staple crop across Asia; it serves as a main nutritional source for Asia's high population. In the 1970s, a pathogen called the grassy-stunt virus greatly decreased cultivated rice plant populations in Asia. Scientists found one wild relative
of the rice plant in India that was resistant to the grassy-stunt virus, and today hybrid rice plants with that resistant gene are grown across Asia. To find this one rice plant species, approximately 17,000 rice plants samples were tested over the course of 4 years. If you were a scientist working on this project, how would you argue that the results of the research would be worth the time investment? A) Finding the wild relative with disease resistance would help avoid extirpation of fungus that has a mutualistic relationship with the cultivated rice plants. B) Finding the wild relative with disease resistance would protect the continent of Asia as a biodiversity hot spot. C) Finding the wild relative with disease resistance would allow Asian farmers to continue to grow the crop they know. D) Finding the wild relative with disease resistance would help deter invasive species of rice plants.
