Answer: Low, High, Lac repressor
Explanation:
The expression of the lac structural genes is low when lactose is absent from the culture medium and is high when lactose is added, because lactose binds to the lac repressor and inactivates it.
When Lactose is present the lac genes is expressed because the substrate lactose act as inducer and binds to the lac repressor and inactivate it. So the gene is expressed.
But in the absence of lactose, the lac repressor binds the DNA and prevent the expression of the lac genes
Answer:
Producers ( also called autotrophs) are the organisms that synthesize their own ( glucose) food using carbon dioxide and water in the presence of sunlight ( photosynthesis). They use energy from sunlight to convert it into chemical energy ( that is stored in the glucose). Autotrophs occupy the base of a food chain within the ecosystem as they are first trophic level for the energy transfer.
Decomposers ( such as bacteria and fungi that act on dead plants and animals) can recycle the organic matter back into the food web and biogeochemical cycles in the form of nutrients such as carbon and nitrogen.
Thus, the correct answers are-
1) Producers
2) Decomposer
3) Sunlight
4) Base
