Answer:
c. Tubulin
Explanation:
Tubulin protein is polymerized to form the cylindrical structures of microtubules. Microtubules form the spindle apparatus during cell division. The spindle microtubules become attached to the kinetochores of chromosomes and mediate the alignment of chromosomes at the equator of cells during metaphase. The shortening of spindle microtubules is responsible for the movement of sister chromatids during anaphase. The same event also moves the homologous chromosomes during anaphase-I.
Any failure in the formation of the spindle apparatus would not allow the proper separation of chromosomes. Therefore, the cell with abnormal chromosome separation might have a faulty or no tubulin.
After a caterpillar eats a leaf, it can convert the chemical energy into mechanical energy to help it build a cocoon.
Photosynthesis is the opposite of cellular respiration.
glucose is converted into ATP during cellular respiration.
Light energy + Oxygen = Glucose
We breathout CO2 during the process of cellular respiration.

Answer:
An allele is one of two, or more, forms of a given gene variant. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles. Nearly every living human's phenotype for the ABO gene is some combination of just these six alleles.
