Answer:
Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
Explanation:
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.
B because when the positive feedback happens it increases the temperature and when the negative feedback occurs the temperature lowers itself
All cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.
<h3>What is an
epithelium?</h3>
An epithelium is a specialized layer of cells that play different roles in the organism (e.g., transport of substances, digestion, etc).
Epithelia are one of the four types of tissues that form the body, which also include connective tissue, muscle tissue, and nervous tissue.
The ciliated columnar epithelium is a special class of epithelium that contain cilia that are used to move substances across their cellular surfaces.
In conclusion, all cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.
