They attach to the centromeres and pull apart new chromosomes to the opposite poles of the cell
Dafna1 [17]2 years ago
6 0

Answer:

Spindle fiber is made up of microtubules that originates from the centriole present at both the poles of the animal cell. Plant cells do not contain centriole but can generate spindles from centrosomes.

During the mitotic cell division, the spindle fiber attach to a specialized structure made up of a protein complex called kinetochore which is present on the centromere of mature chromosome. Then these spindle pull the chromosome toward the pole through their centromere.

These spindle fibers help to separate the chromosomes during nuclear division in mitosis but it also helps in chromosome editing by holding two sister chromatids at their position together.  

The separation of chromosome is necessary so that after cell division both the daughter cell contains genetic material.

How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is need
Tasya [4]

Answer: More than 1

Explanation:

A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.

Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.

The black dots that cover strawberries are actually individual fruits. The fleshy and tasty portion of a strawberry derives from
yaroslaw [1]

Answer:

C) both an aggregate fruit and an accessory fruit

Explanation:

When several flower ovaries or receptacle of a flower with many separate carpels joins together they form aggregate fruit. Each ovary has a single ovule that converts into a seed after fertilization.

Aggregate fruit can be formed without the involvement of accessory parts called true aggregate fruit or with the involvement of additional floral parts called accessory aggregate fruit. Strawberry is also an accessory aggregate fruit because the different ovaries in the strawberry develops into achenes over the surface of flower receptacles.
