True, the process is called the sliding filament model of muscle contraction.
According to the sliding filament theory, muscle proteins slide past one another to produce movement during muscular contractions. The sliding filament theory postulates that during muscle contraction, the actin (thin filaments) and myosin (thick filaments) of muscle fibers glide past each other while remaining at essentially constant lengths. A protein called myosin transforms ATP (chemical energy) into mechanical energy, causing movement and push. T
his motion causes the muscles to contract and non-muscle cells, like those in the mitosis and meiosis, to move (cell division). Additionally, the actin-myosin interaction and actin polymerization are what cause a cell to move across a surface. When troponin molecules link to calcium ions in filaments, actin filaments' myosin-binding sites become visible, promoting bridge construction. ATP serves as an energy source and powers this process. Myosin molecules' heads undergo ATP hydrolysis, changing their shape and allowing them to bind to actin filaments.

I believe that when you get older your lenses get less flexible. I would recommend you do more research on it, but some people’s eye sight worsens because of their habits. Such as standing too close to the telly or gaming for hours.
Hope this helps!
Answer:
Population size is influenced by the per capita population growth rate, which is the rate at which the population size changes per individual in the population. This growth rate is determined by the birth, death, emigration, and migration. Pretty much Birth rate or Death rate.
