Explanation:
Answer 2
Answer:

Answer:

Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization. For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.

Which statement correctly uses the model above to explain how mitosis maintains genetic continuity? A. The chromosomes in cell 1 are the same as in cells 6.B. Crossing-over occurs in cell 4. which increases genetic diversity in cells 6.
C. When the nuclear membrane reforms in cell 5. each nucleus becomes diploid in number. Option 3
D. The independent assortment that is represented in cell 2 ensures that cell 3 has the correct number of
chromosomes.

Answers

The statement that correctly uses the model to explain how mitosis maintains genetic continuity would be that the chromosomes in cell 1 are the same as those in cell 6. The correct option would be A.

Mitosis refers to the division of vegetative cell. When a cell divides by mitosis, the daughter cells produced have the same genetic components as the original cell. Hence, the daughter cells continue carrying the genetic components as the parent cell.

In the model, cell 1 is the one dividing and the daughter cells are the two cells in 6. The cell in 1 and those in 6, therefore, must have the same chromosomes in order for genetic continuity to be maintained through mitosis.
