Answer:
Take a village and divide the population in two, with an experimental group that will be given a different diet, and a control group which will continue with their normal diet.
Explanation:
In experiment design, when we want to test whether or not certain factor actually has a real effect on a population, one of the best methods to follow is to split the population in two groups: an experimental group, where we will apply the treatment, and a control group, where either a placebo or no treatment at all will be applied. The advantage of having both an experimental and a control group is that this way we can ascertain with much more clarity whether a change in the indepent variable (the treatment) has an observable effect on the dependent variable (the effect on the population).
In our example, a practical manner to test whether longevity in Russian Georgian villages is due to genetic or dietary factors, is to take one of the villages, and split the population in two groups: an experimental group, that will be given a higher calorie diet, and a control group, which will continue to consume their normal low-calorie diet. Then we would track the differences in age expectancy over time. If after a long enough period of time there's a difference in longevity between both groups, in other words, whether one of them leads longer or shorter lives than the other, then we can conclude that our test has proven that diet has a definitive effect on their longevity. If there's no significant difference, then we can conclude that diet has no relevance and it's all due to genetics.
Answer:
False
Explanation:
Values are the set of characteristics of a particular person or organization that determine how they behave and interact with other individuals and the environment. According to this conceptualization, we can state that the information shown in the above question is false.
Thus, these values can be considered as the basis of human and social relationships, functioning as a set of norms that guide human interactions and decisions.
Answer:
ribosomes
When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains.
Explanation:
Answer:
D. Articulate and appealing vision
Explanation:
Most of the time people that are in the throws of circumstances that are extremely uncomfortable are willing to listen to a promise. While a charismatic leader is one that needs to be eloquent and set an example to the followers and have a direct plan of action they must first come with a dream.
As an example Barrack Obama was the first "African American" president of the United States of America. He did not specifically fit the description of many as "African American" due to his parentage. His mother was Causation and his father was African and had never had any descendants that were slaves.
This, however, did not stop him from appealing to the minorities with the slogan "Yes, we can". This was eerily parallel to the spiritual hymn "We shall overcome someday". The dream of the U.S.A.'s first black president was a tangible reality.
This is not to say that he was not competent for the job but first appealing to a dream is the beginning of the win for the favor of the people.
