What structure acts as a scaffolding for chromosomal attatchment and movement?
Spindle acts as a scaffolding for chromosomal attachment and movement. Chromosomes attach to the spindle fibers by undivided structures called centromeres.
What stage are the chromosomes shorten by condensing their nucleoprotein is called?
The stage where chromosomes shorten by condensing their nucleoprotein is called prophase during mitosis. This is when the chromosomes become visible and appear as distinct structures under a microscope.
What is The pair of structures involved in an animal cell division is called?
centrioles
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
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.

What is The pair of structures involved in an animal cell division is called?
centrioles
The structure that acts as a scaffolding for chromosomal attachment and movement is called the?
'kinetochore.' It is a complex protein structure that forms on the centromere region of the chromosome and is responsible for attaching the chromosome to microtubules during cell division, allowing for proper alignment and segregation of chromosomes.
What are the fibers that shorten and pull the chromatids apart called?
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
Who examined stained cells and found rods he called chromosomes?
The scientist who examined stained cells and found rods he called chromosomes was Theodor Boveri. He made important contributions to the understanding of chromosomal behavior during cell division.
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.
What muscles are called voluntary muscles?
because its attach to the bones movement is a shorten shorten contrast
What did walther Flemming do?
Walther Flemming was a German anatomist who is known for his discovery of chromosomal structures in cells. He first observed and described the process of cell division, which he called mitosis, and identified the presence of thread-like structures that we now know as chromosomes. Flemming's work laid the foundation for our understanding of how genetic material is passed on from one generation to the next.
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
The structures within the muscle fiber that shorten to cause skeletal muscle contraction are called myofibrils. Myofibrils are composed of repeating units called sarcomeres, which contain thick and thin filaments made of proteins (actin and myosin). When the muscle fiber is stimulated by a nerve impulse, the myosin heads interact with the actin filaments to generate the force required for muscle contraction.
Which appears during cell division?
log-like structures found during cell division are called centrioles.
What is it called when you shorten a repeated decimal?
rounding
