Answer: D) cAMP
Explanation:
In the absence of glucose cell can make use of other sources of carbohydrates such as lactose. In E. Coli and other bacteria utilization of lactose depends on the availability of cAMP. Bacteria accumulate cAMP only when starved. When glucose is exhausted, cAMP is available in plenty.
cAMP is necessary for the gene expression because it binds catabolite repressor protein (CAP) to form CAP-cAMP complex. CAP is a lac repressor the binds to the operator site of the lac operon preventing RNAP From binding to the promoter.
RNA polymerase can bind to the promoter site only when CAP-cAMP formed
Answer:
True
Explanation:
Earlier it was believed by researchers that sleep is not a good thing as it does not allow an organism to stay alert all the time due to which there are high chances of such organism being consumed by other organism. However, with the discovery of theory of evolution, it is now believed that sleep has also evolved. Its evolution allows an organism to save energy and conserve it.
Evolved sleep has helped decrease synaptic strength which allows a person to preserve memories and function well during the day time. REM sleep in the early morning makes brain metabolically active even while sleeping and hence, dream comes.
Answer:
Due to different reproduction methods.
Explanation:
Organisms from eubacteria, plantae and animal kingdom are used different reproductive strategies which leads to genetic diversity. Bacteria use asexual reproduction which produces identical offspring while on the other hand, plants and animals use sexual reproduction that produces offspring that is different from plants which leads to variation in the organism so that's why we can say that different reproductive strategies is responsible for genetic diversity.
Is this opinion-based? i would say B, false, but i could see it being A as well.
