Hope this helps
Plz give me Brainliest.
Lit is located between the
left ventricle and left atrium.Left atrium is known to be one of the four chambers of heart
that receives oxygenated blood from the right and left pulmonary veins. This blood
is pumps to the left ventricle through the mitral valve. However, left
ventricle is responsible for pushing oxygenated blood through the aorta to the rest
of the body.
Answer:
Microtubules composed of tubulin protein.
Explanation:
The cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.
Microtubules are long hollo cylindric tubes with no ramifications of a diametre near to 25 nanometers. They are constituted by two subunits of tubulin protein which polymerize to form microtubules. These filaments shape the cell and are involved in intracellular transport. Microtubules extend from an organizing center near the nucleus to the cellular surface.
some one celled organisms reproduces by binary fission which is a process of cell division. The answer is 4.
