Answer:
Explanation:
The <em>correlation coefficient</em> is a measure of the linear association between two variables.
It is a dimensionless value bettween - 1 and +1. Hence, it does not depend on the units that are used to measure the data.
You can see the formula to calculate the correlation coefficient in the attached picture.
There you see that the numerator containts the sum of the differences of the values of the x-variable with its the mean, multiplied by the sum of the differences of the values of the y variable with its mean, while the denominator contains the square root of the product of the squares of the same differences, thus the units are canceled.
In conclusion,<em> If the teacher changes the units of each variable from hours to minutes, the value of the correlation coefficient between minutes studying and minutes spent on the Internet will not change</em>; it will continue being <em>−0.72.</em>
The disruption which is not a major cause of a high rate of species extinction on planet Earth is: c. earthquakes.
<h3>What is extinction?</h3>
Extinction refers to a situation in which a species, family, or other taxonomic group of living organisms such as animals or plants become extinguished, destroyed, or exterminated (dead).
This ultimately implies that, extinction literally means the extermination of a species, family, or other taxonomic group of living organisms. However, earthquakes are disruption which aren't a major cause of a high rate of species extinction on planet Earth.

Answer:
The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria.
