What else can I help you with?
What ist the process called that causes the cell to contract or shorten?
This process is called contraction. Muscles shorten or contract to produce movement.
Contraction of a muscle resulting in its shortening?
A muscular contraction that causes a muscle to shorten is called a concentric contraction. A concentric contraction is a type of isotonic contraction.
A muscular contraction that causes a muscle to shorten as it develops tension is called?
A cramp is a sudden over-shortening of a muscle. Cramps are involuntary and, often, severe. They can be extremely painful.
How does strings make a musical sound?
Because when you pluck/strum etc a string it vibrates, and this causes the sound. If you lengthen or shorten the string, the pitch changed (longer:lower, shorter:higher) Hope this helps!
What mechanical force of contraction is generated?
The mechanical force of contraction in muscle cells is generated by the sliding of actin and myosin filaments during the process of muscle contraction. This sliding is driven by the interaction of myosin heads with actin filaments, which causes the filaments to overlap and shorten, resulting in the generation of force.
What is it called when materials shrink as they cool?
This phenomenon is called thermal contraction or simply contraction. When materials cool, the decrease in temperature causes the atoms and molecules to slow down, leading to a decrease in volume and a contraction of the material.
How do cross bridge power stroke bring about shortening of muscle contraction in human?
During muscle contraction, the cross-bridge power stroke occurs when myosin heads bind to actin filaments and then pivot or "power stroke," pulling the actin filaments towards the center of the sarcomere. This action causes the muscle fibers to shorten, resulting in overall muscle contraction.
What causes a males voice to become deeper?
The vocal cords lengthen ad you get taller
When does light refracts?
Because when light enters a new substance, its speed changes. In order for the law demonstrated in the equation (frequency = speed/wavelength) to remain the same, the wavelength of the light particle/wave must shorten or lengthen. This change causes the wave to slightly refract to one side or the other.
What is second stimulus before relaxation causes increased force called?
The phenomenon you are referring to is called the second stimulus before relaxation, which causes increased force, is known as the treppe effect or the staircase phenomenon. This is characterized by the successive increase in muscle contraction force when muscle fibers are stimulated with increasing frequency.
How does changing the frequency of a wave affect its wavelength?
It causes the wavelength to shorten
A muscle that causes a desired action?
Nerve impulses that originate in the central nervous system cause muscles to contract. Muscle fiber generates tension during the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same.
