Answer:

d. a single variable.

Explanation:

<em>A controlled experiment is one in which the researcher can can keep all other factors/variables uniform and see the effects of a particular factor/variable on certain subjects. </em>

For example, in order to determine the effects of different light intensities on the growth of a plant species. All the growth conditions will be uniform for all the subjects (the plant species) except the light intensity. Any discrepancy in growth can thus be attributed to the different light intensities.

The light intensity is varied while other factors are kept uniform.

why is it a good idea for a bacterial cell to be abel to use glucose first as an energy source then switch to lactose
olchik [2.2K]

Answer:

Due to less steps and requires less energy.

Explanation:

The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.
