Answer:
The strategies used to treat osteoporosis are as follow:
- A diet based on foods rich in calcium and Vitamin D (e.g., poultry and fresh fruits)
- Regular sun exposure
- Regular physical exercise
Explanation:
Osteoporosis is a prevalent disease in older people that makes bones more fragile/porous, and therefore more likely to suffer breaks. This condition can substantially reduce the quality of life, especially in people aged at least 65 years. Osteoporosis is caused by poor nutrition, i.e., by the lack of foods rich in nutrients, especially rich in calcium and vitamin D (e.g., milk, fresh fruits, etc), which leads to a decrease in bone density. In UAE, it has been shown approximately 70 % of its population suffers from Vitamin D deficiency and calcium deficiency. Exposure to the sun helps the body to synthesize vitamin D, contributing to prevent this disease. Moreover, regular physical activity may improve bone density and therefore reduces the risk of fractures derived from osteoporosis.
Answer:
Respiration uses NADH as an electron carrier, fermentation does not
Explanation:
Respiration is the process of chemical reactions, in oxidising food to generate energy.
Fermentation is chemical breakdown of organic substrate, like glucose, by microrganisms like bacteria & yeast.
Difference between them is that : Respiration process uses NADH in oxidative phosphoralytion for ATPs . However, fermentation doesn't include use of NADH in oxidative phosphoralytion for ATPs.
It would cause competition
they will strive to get the resources they need but because there are so many some may not get enough nutrients
