Answer:
False
Explanation:
The poles are covered by Ice at most seasons of the year
the forelimb help with balance and crawling and the hind limbs are stroger than the forelimbs and they are used for jumping/hopping
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells

They are classified in :-

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.
