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.

Answer:
The superior colliculus
Explanation:
Superior colliculus is an organ in the midbrain and a multilayered sensory structure. It transform sensory signals into eye movement.
Superior colliculus is the part of the corporal quadrigemina that is clearly observed in a mid sagittal section.. it is clearly observed in transfered fissure backward of the mid brain and it is responsible for eye movement direction.
Answer:
The structural components of the nervous system enables it to carry out the following functions:
1). collect information about changes in the organism's environment (both internal and external).
2). process the information; and
3). act up on the information.
The nervous system carries out its functions efficiently and extremely rapidly since information and instructions speed as electric impulses along nerve from one part of the body to another almost instantaneously.
The basic structural unit of the nervous system is the nerve cell or neurone which consists of a dense cell body and protoplasmic processes collectively known as nerve fibre.

D) competition for resources is greater
The more in the population, the more resources needed. If they run out of resources, the population decreases. They are competing to stay alive. I hope this helps!
