Answer:
Archaebacteria are found in very harsh conditions such as in the volcanic vents or at the bottom of the sea. They are often called "extremophiles". They can easily survive in such extreme environment as sea vents releasing sulfide-rich gases, hot springs, or boiling mud around volcanoes.

Answer:
<em>Repeated growing of crops in the soil decreases the fertility of the soil as the crops use up the nutrients of the soil. ... Farmers replenish the soil of the depleted nutrition with the help of fertilizers or crop rotation. Fertilizers are chemical substances that are rich in a particular nutrient.</em>

Answer:
this mutant will not be able to use lactose
Explanation:
The lac operon is a cluster of genes with the same promoter which are transcribed as a single messenger RNA (mRNA). The lac operon encodes different enzymes that are used by the bacteria to obtain energy from lactose. The LacI gene is required for producing a repressor protein that binds to the promoter of the operon in order to inactivate its transcription (i.e., by preventing RNA polymerase from binding). A mutation in this gene prevents from its binding to lactose and it becomes inactive to the Lac operon.
