Answer:
Plants harvest energy from the sun with the help of chlorophyll and carotenoid, two photon-capturing molecules. But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.
Hubble's Law is the recessional velocity, which is the speed of a celestial body moving away from the observer, is proportional to its distance.
It states The Universe is expanding, our galaxy is expanding, red shift is proportional to a body's distance from us, and red shift is proportional to distance form the center of the universe.

Answer:
Glucose serves as a major source of energy for metabolic processes in mammalian cells. Since polar molecules cannot be transported across the plasma membrane, carrier proteins called glucosse transporters are needed for cellular uptake.

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.
