Answer:

This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.

Explanation:

Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).

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.

It is crucial that the process of mitosis is error free. This is because otherwise healthy cells can
kherson [118]

The correct answer is that it becomes cancer cells.  

Mitosis refers to the kind of cell differentiation, which leads to the formation of two daughter cells, and each comprising the same type and amount of chromosomes as the parent nucleus, generally of ordinary tissue growth.  

The process of mitosis should be error free as otherwise healthy cells can turn into cancer cells. Cancer is basically a disorder of mitosis, in this case, the usual checkpoints, which are monitoring mitosis are overridden or ignored by the cancer cells.  

Cancer initiates when a single cell is converted or transformed into a normal cell to a cancer cell and is generally taking place due to a modification in function of one of many genes, which usually work to monitor growth, like p53 gene or tumor suppressor gene.
