The sliding filament theory is the explanation for how muscles contract to produce force. As we have mentioned on previous pages, the actin and myosin filaments within the sarcomeres of muscle fibres bind to create cross-bridges and slide past one another, creating a contraction.
Answer:
Prophecy.
Explanation:
Self-fulfilling prophecy is a socio-psychological phenomenon of someone predicting or expecting something, positive or negative, and this prediction (prophecy) or expectation comes true simply because one believes it will, and their resulting behaviors align to fulfill those beliefs, including the act of predicting it (self-fulfilling). This suggests peoples' beliefs influence their actions/behaviors. The principle behind this phenomenon is people create consequences regarding circumstances, people or events, based on their previous knowledge toward that specific subject solely based on one’s interpretation of a certain situation. In this case, if the students failed previous math classes, they will fail again because they believe they are going to.
