b. Rotate into a position (cocked) to bind to actin.

Explanation:

The cycle starts with the myosin strongly united to the actin (in absence of ATP). The union of ATP dissociates the myosin from the actin and the ATP hydrolysis induces a conformational change in the myosin. This change affects the neck region of the myosin, which acts like a lever arm displacing the head group of the myosin. The ADP and phosphate stay united to the myosin head, which unites to the actin filament in a new position, liberating the phosphate and releasing ADP. This way, the myosin head adopts again its initial conformation.

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
