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.
Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

The 4 in the middle are the genotypes and the phenotypes are Round green, wrinkled green, round yellow, wrinkled yellow
C = dominant
c = recessive (cystic fibrosis)
CC, cc = homozygous (homo = same)
Cc = heterozygous (hetero = different)
Recessive traits are expressed only when two recessive alleles are present
If you get CC, you will not have cystic fibrosis. (<span>c </span>is the cystic fibrosis allele)
This person would be homozygous dominant and would not pass on the disease because they do not have any cystic fibrosis alleles.
If you get<span> Cc</span> you will not have cystic fibrosis b/c the<span> C</span> is dominant and overrides the cystic fibrosis allele c.
This person would be heterozygous and, though they do not have the disease, they would still have a chance of passing on the disease because they carry the cystic fibrosis allele.
If you get cc you will have cystic fibrosis b/c c is the cystic fibrosis allele and it is not being overridden by a dominant allele.
This person would be homozygous recessive.
