Answer:
Osteoporosis
Explanation:
Osteoporosis is a more common condition in women over 45 that leaves bones fragile and porous. As it progresses with advancing age, the disease increases the risk of fractures, especially in the wrist, spine and hips.
The structure of our skeleton lives in constant renewal. We gain bone mass by age 20 and lose more quickly after 40. Two types of cells - osteoclasts and osteoblasts - are involved in the bone renewal cycle. Osteoclasts promote the absorption of minerals, eliminating areas of bone tissue and creating cavities.
Osteoblasts, in turn, are in charge of filling these cavities, producing new bones. For this they use calcium, absorbed with the help of vitamin D. Thus, every three months 10% of the skeleton renews itself.
Testing facilities that engage in animal testing dispose of both animals and dangerous chemicals, food waste, and a variety of supplies used during the testing process. Not to mention, animal testing has a heavy impact on water and air quality. Additionally, animal testing is cruel and ineffective. Animals don't get many of the diseases that humans do. For example, major types of heart disease, many types of cancer, HIV, Parkinson's disease, and schizophrenia. 100 million animals are killed each year due to animal testing.
