Which type of operon, an inducible one or a repressible one, would an organism likely use to produce enzymes and other proteins

Answer:

Repressible operon

Explanation:

In a repressible operon, a corepressor binds to the repressor to activate it. The active repressor then binds to the operator to prevent the expression of the operon.  These operons have the genes that code for the enzymes required to make molecules from simpler substances. When the molecule is already present in the cell, it serves as a corepressor to prevent the expression of the genes.

For example, tryptophan operon is expressed only when tryptophan is not present in the cells. Tryptophan serves as a corepressor to prevent the expression of the operon.

As you may know, people’s physical and emotional health interact: One can affect the other. The characters in "In Another Countr
Margaret [11]

Answer:

To preserve their mental health, the characters must keep in mind that all suffering is temporary and although it is difficult, they will overcome this situation. What can help characters deal with their situations is by reasoning about the following questions:

"What led me to this situation?"

"What are my limitations in dealing with this type of problem?"

"How could I have acted to minimize the impacts of suffering?"

"Would any action by me prevent these disorders?"

Explanation:

Every time that the characters evaluate themselves and correct their behaviors, they will be able to follow the emotional evolution that will help them to deal with all their suffering. In this journey, each one has a different rhythm. In fact, we are different in almost every aspect of our physical and mental makeup. The variations in intelligence are enormous and also those related to aggressiveness, intensity of fears and the ability to deal with them. It would not be fair, therefore, to tell a character (or a person) that he is suffering from "nonsense". What is small for one may be large for the other. Underestimating the pain of others is not synonymous with help, but a lack of empathy.

We do have a duty and obligation, in the name of our own well-being, to try to get rid of our pains as quickly as possible, but that does not mean not feeling them. Some people do it more easily, while others "fall in love" with the problem and think about it in a recurrent and obsessive way. They silence the word, but the mind goes on chattering.
