Answer:
ATP is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. ATP then provides the energy to pull the myosin back, by hydrolysing to ADP + Pi.
After age 50, bone breakdown (resorption) outpaces bone formation and bone loss often accelerates, particularly at the time of menopause.
What is Osteoporosis ?
Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.
Osteoporosis is a disorder where your bones become brittle, fragile, and easily breakable as you age because certain minerals begin to leach out of them. Because estrogen, which helps keep bones strong, is lost during menopause, women over 50 are particularly at risk for osteoporosis.

The goal of environmental science is to demonstrate the importance of the interrelationships between the different physical and biological components of the biosphere and to develop a set of scientific concepts and concepts to directly assess the causes and possible relationships to crises. environmental shaking our societies.
Earth's environment is constantly changing, especially in recent years with the advent of industry, deforestation and increased pollution that has disrupted many systems at the level of the biosphere (physical and biological), so the need of environmental scientists so that it can predict future events and how to restore the biosphere system.
It is because that's a place where no one lives so they're safe.
