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.
Answer:
The correct answer is D. A higher education level automatically makes a candidate more qualified for a particular job than a candidate with a lower education level.
Explanation:
Education is necessary for every person because it improves the understanding of that person and helps him to build a self-opinion. Education improves economic growth and increase the value of that person in his society.
Organizations have vacancies according to the education qualification of a candidate, therefore, a candidate having a higher education level is more qualified than the candidate having a lower education level.
For example in a research job a Ph.D. holder is more qualified than a MSc. degree holder. Therefore the right answer is D.
Quality physical education programs are needed to increase the physical competence, health-related fitness, self-responsibility and enjoyment of physical activity for all students so that they can be physically active for a lifetime. Physical education programs can only provide these benefits if they are well-planned and well-implemented.
