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.

Which of the following has the fewest taste receptors?
kolbaska11 [484]

Answer:

filiform papillae

Explanation:

The filiform papillae, also called conical papillae, are sensory receptors distributed on two thirds of the lingual dorsum. They are the most abundant papillae on the surface of the tongue and are not associated with taste reception because they have the smallest number of taste receptors.

These papillae are arranged fairly evenly in rows parallel to the central groove of the tongue, especially in the center and back. These papillae are made up of connective tissue and an epithelium that expresses keratin, a protein present in people's skin, hair and nails.
