Studentka2010 [4]

Answer:

Carotenoids and Anthocyanins

Explanation:

During the winter the sunlight is limited for a long period of time. Plants will lose their leaves but first they will turn bright colors. The reason for this is as follows:

Plants' leaves appear green because of the presence of chlorophyll. During the fall the plants attempt to save energy. So, before they drop the leaves they first break down the chlorophyll into smaller molecules so they do not have to make the molecules from scratch all over again when spring comes. What is left behind is the Carotenoids that appear yellow and orange and Anthocyanins that appear purple.

Which statement best describes the data set?
zhannawk [14.2K]

Answer:

It is neither accurate nor precise.

Explanation:

<em>The data set is neither accurate nor precise.</em>

Accuracy is defined as the closeness of a measurement to the true value.

Now let us look at the average of the data set:

30 + 17 + 27 + 21 + 32 = 127/5 = 25.4

<u>The average of the data set is 25.4, whereas the correct value provided is 25. The difference between the average of the data set and the correct value is 0.4 which is beyond the margin of error allowed in measurement. Hence, the measured data is not accurate.</u>

Also, precision is defined as the closeness of repeated measurement to one another.

<u>From the data set, the individual values are not close to one another in any form and the difference between them are more than the margin of error allowed in measurements. Hence, the data is far from being precise.</u>
