The protein that interacts with actin to form a cross-bridge is myosin. Myosin is a motor protein that binds to actin filaments in muscle cells, facilitating muscle contraction through a process known as the sliding filament theory. When ATP is hydrolyzed, myosin heads attach to actin, pull the filaments past each other, and then detach, enabling repeated cycles of contraction.

Until 1749, there were only a few bridges crossing the River Thames in England. The most notable was London Bridge, which had existed in various forms since the Roman era. Other bridges, like those in Kingston and Richmond, were also present but far fewer in number compared to today's extensive bridge network. Overall, the infrastructure for crossing the river was limited before the mid-18th century.

The Arch of Serendipity is not a physical structure recognized in historical or architectural records. It is often referenced in literature and discussions about unexpected discoveries or fortunate accidents, drawing from the concept of "serendipity."

Immigrants often bridged the language barrier by forming tight-knit communities where they could communicate in their native language while learning the local language together. They utilized resources such as language classes, cultural organizations, and informal language exchanges to improve their proficiency. Additionally, many relied on bilingual individuals within their communities to assist with translation and interpretation, facilitating smoother interactions in daily life and at work. Over time, these efforts helped integrate them into the broader society while preserving their cultural heritage.

The saying "water under the bridge" originates from the idea that water flowing under a bridge is in the past and cannot be changed or retrieved. It suggests that certain events or issues should be let go and not dwell upon, as they are no longer relevant. The metaphor emphasizes the importance of moving on from past grievances or situations. This phrase has been used in English since at least the early 20th century.
