The answer is C. Race is a social construct, and does not exist in biology.
Answer:
Strong positive
Explanation:
In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.
- Two variables have a positive correlation when if one increases the other increases too.
- Two variables have a negative correlation when if one increases the other decreases and vice versa.
Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.
In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>
Thus, Isabella would conclude that this is a strong positive relationship.
The correct answer to this open question is the following.
The impact of the commercial revolution (16th century ) in Western Europe was the following.
The commercial revolution's impact was that it generated a big competence between European countries in trade. The rules of trade and commerce dramatically changed due to the Columbian exchange and all the goods, raw materials, and natural resources were affected due to this competence between European nations, supply, and demand.
The commercial revolution also saw the beginning of financial institutions and the surge of banking institutions that coined money and made loans.
Answer:
I would say: In the summer, new leaves grow for absorbing light as the Sun becomes hotter. - there are no new leaves produced in the summer
Explanation:
Some trees keep their leaves all year round for Photosynthesis - this is true because they keep their needles year-round, in the winter pine trees are able to photosynthesize!
In the autumn, most trees lose their leaves to save energy through the darker winter - is true because the main reason for leaf drop on most trees is that, come winter, it gets pretty cold and dry in our part of the world. Rather than expend energy to protect these fragile organs, trees shed leaves to conserve resources.
In the spring, new leaves grow for absorbing light as the Sun becomes hotter .- YES! this is true , and new leaves do not grow back in the summer it only continues to grow bigger
Explanation:
The most appropriate reply would be the Meeting increased competition in Europe with the recent recession leading to the weakening of the euro is going to be a challenge. Because of the increased competition in Europe and the recession the value of Euro is gone down because of which it will be very difficult to predict the pricing objective of work.
Rest of the options are incorrect as prestige pricing will not be suitable here, probability can be accurately judged by primary and secondary research and also last option is not very relevant to the subject.
