Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
Answer:
The term “epigenetics” was introduced in 1942 by embryologist Conrad Waddington, who, relating it to the 17th century concept of “epigenesis”, defined it as the complex of developmental processes between the genotype and phenotype.

Answer:
It's C.
Explanation:
I chose B but I got it wrong. Since lizards obviously have dry skin, the other option with lizards is C. And you can also see in the cladogram that above "dry skin" is lizards and tigers.
So it's C.
Answer:
Eukaryote and Prokaryote
Eukaryotes have a nucleus and prokaryotes don't
I believe the answer is the global free-market approach.
It is because on continually increasing use of earth's natural capital, and it focuses on short term economic benefits with little regard for degradation and depletion of natural capital and resulting long-term harmful environmental, health, and social consequences. Environmental world views are the ways of thinking about how the world work and beliefs that people hold about their roles in the natural world, another factor is widespread lack of understanding of how earth's life-support system works, keeps us alive, and supports economies.
