Answer:

mutation in DNA

Explanation:

Mutations are changes in the genetic code that can occur in many ways. Each time a cell divides, say, DNA must be copied into two copies, one copy for each new cell. Although this copying is very precise, it is still not perfect - for about every billion accurately copied databases, one is mistranslated.

Another source is DNA damage, which can occur spontaneously through the normal life of the cell, or through external toxins or negative influences (ultraviolet radiation, for example). Through evolution, cells have developed a very complex system for repairing changes in DNA, but these systems not only have limitations but can sometimes cause additional errors themselves.

A researcher examining a root tip observes a plant cell with condensed sister chromatids, kinetochores with attached microtubule
Basile [38]

Answer:

The statement 2 best describes the next process taking place within the cell.

Explanation:

A kind of cell division, which is characterized by the differentiation of a single parent cell into two daughter cells that comprise equivalent chromosomes number is termed as mitosis or reductional division. In the given case, the arrangement of chromosomes at the equatorial plate indicates that the cell is currently in the metaphase stage of mitosis.  

After going through the stage of metaphase, the cell moves into the anaphase stage. In the anaphase stage, the sister chromatids begin to segregate and move towards the opposite pole of the cell. Thus, statement 2 correctly illustrates the next stage of the cell.

yKpoI14uk [10]
I believe that in developed nations, the nutrients that are most lacking in a child's diet are the; calcium, iron and zinc. Zinc is needed for the activity of more than 100 different enzymes in the body and plays a role in the immune function. It aids in the maintenance of healthy immune function in kids and may reduce the frequency of mild upper respiratory tract infections. Calcium keeps the bones healthy and teeth thus supporting the skeletal structure and function. Iron is an important component of hemoglobin.
