Nocardia is important in bioremediation process because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.
<h3>What is bioremediation?</h3>
Bioremediation is the process of using living organisms such as microorganisms to degrade wastes in the environment in order to return it to its previous healthy state.
An example of a microorganism used in bioremediation is Nocardia spp.
Nocardia is important in bioremediation because they can decompose polycyclic aromatic hydrocarbons, polychlorinated biphenyls, chlorophenols, sulfonated azo dyes and alkanes.

Answer:
Inducible
Explanation:
When a gene is expressed only under certain conditions such as the presence of an inducer in the environment to inactivate the repressor, the gene expression is said to be inducible. Here, the presence of substance Y is required as it serves as an inducer by inactivating the repressor protein. When the repressor protein is inactivated, RNA polymerase is able to express the gene. This is an example of inducible gene expression. For example, the presence of lactose is required for the expression of genes of the lac operon.
Answer:
Option (2).
Explanation:
Cell division is the process by which cell increases its number with the help proteins and enzymes. The four main phases of the cell cycle are G1 , S, G2 and M phase.
The cell cycle sequence is important for the proper division of the cell. Any change in these sequences might result in cancer and other disease. The skipping or change of any stage might cause the lack of material. The cell will lose the energy to divide or may result in uncontrolled cell division.
Thus, the correct answer is option (2).
The process seen in the image is hay harvesting, which is widely used as fodder.
<h3>What is hay for?</h3>
Hay is a viable alternative to be used as fodder (for animals to feed in the troughs) if there is not enough pasture or the climate is unfavorable for grazing. It is also used for animals that must be kept in the stable or barn (eg when the females are pregnant).
With this information, we can conclude that Hay is a mixture of mown and dried plants that can be used as fodder.
