A student uses gummy worms to model the process of mitosis. The model is shown below.

Using the model, which statement correctly explains how mitosis preserves genetic continuity?
a
The daughter cells receive chromosomes that are recombined from the parent cells.
b
Each daughter cell receives twice as many chromosomes as the parent cell.
c
The daughter cells receive chromosomes that are identical to the parent cell.
d
Each daughter cell receives half of its chromosomes from each of the parent cells.
c
The daughter cells receive chromosomes that are identical to the parent cell.
c
The daughter cells receive chromosomes that are identical to the parent cell.
To answer this question, we need to analyze the gummy worm model of mitosis. The model shows two gummy worms splitting into two identical halves, each with the same number and arrangement of gummy worms.
Mitosis is a process of cell division that occurs in somatic (non-sex) cells. The main goal of mitosis is to create two daughter cells that are genetically identical to the parent cell.
From the model, we can conclude that each daughter cell receives chromosomes that are identical to the parent cell. This is evident from the fact that the gummy worms in the daughter cells are exactly the same as in the parent cells.
Therefore, the correct statement that explains how mitosis preserves genetic continuity is:
c) The daughter cells receive chromosomes that are identical to the parent cell.
