Choose all of the areas in which the United States invoked the Roosevelt Corollary to the Monroe Doctrine.

LekaFEV [45]

The correct answer to this open question is the following.

Unfortunately, you did not attach the options to answer this question.

What we can do to help you is commenting on the following.

Throughout history, the United States invoked the Roosevelt Corollary to the Monroe Doctrine to accomplish some imperialistic and interventionists goals in different Central American and South American countries.

We can set some examples here. For instance, that was the case of the US intervention in the Island of Cuba, in Nicaragua, Dominican Republic, Hati, and the US presence for so many years in the Panama Canal.

Let's have in mind that the Roosevelt Corollary to the Monroe Doctrine was originally called for intervening in Latin American countries that could not pay their debt to European creditors.

The message the US wanted to convey to European superpowers that had interests in this region was that from now on, it was going to be the US business to intervene in the Americas. If Europe tried to intervene, it was going to be understood as direct aggression to the United States.

Answer:

The advise I will offer the next scientist about how the laboratorycan beimproved include the following

Calibration of instruments: Instruments which are used in the laboratory should be calibrated so as to reduce errors and inaccuracy during experiments.

Proper labeling of Samples : This helps to give the scientists an idea of where to find samples and to prevent making mistakes in picking the wrong one. This helps to save time and resources in the lab.

Adequate cleaning and waste disposal: Cleaning of the lab and disposal of the wastes helps to eliminate contamination of samples.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.

Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, TTC⇒TGC. Patient 2: nucleotide 143, TTC⇒TCC. Patient 3: nucleotide 147, TTC ⇒ TTG.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

nucleotide wild-type mutated

location nucleotide nucleotide

Patient 1 143 TTC TGC

Patient 2 143 TTC TCC

Patient 3 147 TTC TTG

In the attached files you will find an image for a better understanding.
