Cross-bridge theory states that actin and myosin form a protein complex (classically called actomyosin) by attachment of myosin head on the actin filament, thereby forming a sort of cross-bridge between the two filaments. The sliding filament theory is a widely accepted explanation of the mechanism that underlies muscle contraction. [6]
EMUs were given six-digit unit numbers, the first three digits representing the class and the last three being a unique identifier. AC EMU class numbers begin with a '3', Southern Region third rail DC EMUs with a '4' and other DC EMUs with a '5'. [citation needed] In the late 1960s, the need for a new EMU design was recognised.
The animals were thought to be a male and female of the same subspecies, but are possibly a Kangaroo Island emu and a King Island emu. [15] Several emu specimens belonging to the different subspecies were sent to France, both alive and dead, as part of the expedition. Some of these are in European museums today.
Complex dynamic systems theory in the field of linguistics is a perspective and approach to the study of second, third and additional language acquisition. The general term complex dynamic systems theory was recommended by Kees de Bot to refer to both complexity theory and dynamic systems theory.
Video interaction guidance (VIG) is a video feedback intervention through which a “guider” helps a client to enhance communication within relationships. The client is guided to analyse and reflect on video clips of their own interactions.

According to this theory, life span development has multiple trajectories (positive, negative, stable) and causes (biological, psychological, social, and cultural). Individual variation is a hallmark of this theory – not all individuals develop and age at the same rate and in the same manner. [15] Bronfenbrenner's ecological theory
The King Island emu was the smallest type of emu and was about 44% or half of the size of the mainland bird. It was about 87 cm (34 in) tall. According to Péron's interview with the local English sealer Daniel Cooper, the largest specimens were up to 137 cm (4.5 ft) in length, and the heaviest weighed 20 to 23 kg (45 to 50 lb).
