Answer:
The correct answer will be
1. Lengthen
2. Lengthen, shortens
3. Disassemble
Explanation:
There are three types of microtubules present during cell division: kinetochore, aster and polar microtubules.
1. During prophase: all types of microtubules grow out at their positive(+) ends which functions to pull and push the sister chromatids apart towards opposite poles so they lengthen.
2. During anaphase : non-kinetochore microtubules- polar microtubules polymerization takes place at their (+) ends which causes the spindle fibres to move apart while kinetochore microtubules which have been attached to the kinetochores of chromosomes shorten at their (+) ends and motor proteins travel to (-) end because of which sister chromatids move towards the spindle poles.
3. During telophase: non-kinetochore microtubules depolymerize or disassembles.
Thus, 1. Lengthen, 2. Lengthen, shortens and 3. Disassemble are the correct options.
Atoms do differ in their affinity for neutrons, a property called electronegativity. Therefore, true is the correct answer.
