olga_2 [115]

Answer:

The best answer choice for the question: Which of the following best describes the results of Dr. Sneed´s study on volunteering and hypertension, would be, D: The risk of hypertension is lower only for people who volunteer more than 200 hours per year.

Explanation:

The study, which was carried out by Rodlescia S. Sneed and Sheldon Cohen, and which was published under the name "A Prospective Study of Volunteerism and Hypertension Risk in Older Adults" was a very interesting one where the correlation between the risk of developing hypertension in older adults, and the hours spent at volunteering activities, 200 or more in a year, regardless of age, sex, origin, race, and other factors, was studied. In the end, the results of this study show that there is, in fact, a relation between the two things and it is believed that the reason is that volunteering in older adults brings positive concepts about self, and others, that affect the body positively. Thus, although volunteering won´t change a person´s hypertensive state and it is not a cure either, it does reduce the incidence of hypertension on the people that were followed for 4 years. The clarification, however, made by the investigators, is that this applies to older adults who volunteered at least 200 hours or more, and not the other group studied, which was the one that volunteered less that 200 and to a minimum of 100 hours per year. This is why the answer is D.

HELPLPPPP<br> Describe how people engage in trading?
jeka94

Answer:

Trade is a basic economic concept involving the buying and selling of goods and services, with compensation paid by a buyer to a seller, or the exchange of goods or services between parties. Trade can take place within an economy between producers and consumers.

A trader is an individual who engages in the buying and selling of financial assets in any financial market, either for themself or on behalf of another person or institution. The main difference between a trader and an investor is the duration for which the person holds the asset. Investors tend to have a longer-term time horizon, while traders tend to hold assets for shorter periods of time to capitalize on short-term trends.

Explanation:

  • Traders are individuals who engage in the short-term buying and selling of an equity for themselves or an institution.
  • Among the drawbacks of trading are the capital gains taxes applicable to trades and the costs of paying multiple commission rates to brokers.
  • Traders can be contrasted with investors, who seek long-term capital gains rather than short-term profits.
