Answer:
e. separate chromosomes during cell division.
Explanation:
The formation of the spindle apparatus starts in the prophase stage of mitosis. The spindle is made of microtubules. The kinetochore microtubules become attached to kinetochores of the centromeres of chromosomes. This attachment helps in the alignment of the chromosome at the cell's equator during metaphase. Depolymerization of kinetochore microtubules shorten them and thereby assist in the separation of sister chromatids to opposite poles during anaphase.
A cell that is unable to polymerize microtubules will not be able to form a spindle apparatus during mitosis. Chromosomes would not be aligned at the equator in metaphase and there will not be the separation of sister chromatids to the opposite poles of the cell during anaphase.
An organism is defined as pathogenic if it can cause diseases in humans. The organisms that cause diseases' like whooping cough, influenza and diphtheria are this kind of pathogen.
Hope that helps!!!
Answer:
C.) B+I-D-E
Explanation:
The correct formula for population growth is the individuals added to the population via birth or immigration, minus the individuals removed from the population via death or emmigration. Therefore the answer is (B+I)-(D+E), or B+I-D-E
