Answer:
Clean rooms are used for biological research in order to prevent the research from contamination of other microorganisms.
Explanation:
Rooms were cleaned before any biological research in order to reduce the intervention of other microorganisms in the research and made the research proof from any impurities. These labs have high atmospheric pressure which decline the growth of microbes and the research will be done in a better way.
Explanation:
Prophase - <em>Pairs of chromosomes separate and move to opposite ends of the cell.</em>
Metaphase <em>-Each pair of chromosomes lines up along the middle of cell.</em>
Anaphase <em>- Each chromosome moves towards, and pairs up with its mate.</em>

The use of artificial fertilizer has helped the tomato plant to grow faster and taller.
- Natural fertilizers such as plant and animal wastes are considered eco-friendly as they are not harmful to the environment. They add nutrients to the soil in a natural way and do not degrade the soil. But, their impact is slow and cannot fulfil all the lacking nutrients.
- On the other hand, artificial fertilisers are harmful to the environment as they degrade the soil
- Still, the farmers prefer artificial fertilizers over natural fertilizers. This is because they help the plant to grow faster and taller by fulfilling the requirement of all lacking nutrients.
Thus, tomato plants are grown faster and taller due to the use of artificial fertilizers. Artificial fertilizers have a greater impact than natural fertilizers and provide the soil with the required nutrients.
