Mitotic chromosomes are times more compact than a dna molecule in its extended form.

The correct answer will be- 10,000 times more compact

Explanation:

The packaging or condensation of the genetic material in the form of chromosomes plays an important role in cell division as the condensed form of chromosome allows the division of the genetic material to the daughter cells.

The condensation of the chromosomes is observed about 10, 000 times more compact as compared to the DNA molecule in its extended form.

Thus, 10,000 times more compact is the correct answer.

genetic variation will increase because of a new habitat and food source.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
