Alina [70]

Answer: D) North Korea

==============================================================

Explanation:

The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.

On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".

Shortness of breath or difficulty in breathing is also called dyspnea and can be acute or chronic. It has various causes, but mainly can be caused by a problem in the heart or the lungs.

B-type Natriuretic Peptide (BNP) reflect the systolic and diastolic activity of the heart and its blood levels can show any heart failure. A BNP test and can help the nurse decide whether the cause of the dyspnea is a heart failure or some respiratory problem.

serg [7]

When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.

Answer: Option C

<u>Explanation:</u>

Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.  

Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil.  However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.
