Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

Answer:
The options are missing, the options are:
A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation
The answer is C
Explanation:
Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.
Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.
 
        
             
        
        
        
Yes. Half life or better known as Radioactive decay is measured in TIME. Such as seconds, minutes, hours, days, years ect...
