Question

question 8 (5 points) listen whats the dependent variable that impacts the amount of solar energy in a location? a) prime meridian b) equator c) latitude d) longitude question 9 (5 points) listen in an experiment, overweight mice are put on an exercise wheel every day for an hour. the scientist is exploring whether running in the morning, afternoon, or night leads to the greatest weight loss. the caloric intake of the mice remains the same. whats the dependent variable in this experiment?

Explanation:

Question 8

• Prime meridian (A) is a longitude line, not related to solar energy amount by location.
• Equator (B) is a latitude - based reference, not the variable.
• Latitude (C) affects solar energy as it determines solar angle/insolation; longitude (D) doesn't impact solar energy amount by location. So latitude is the dependent variable impacting solar energy.

Question 9

• The independent variable is the time of running (morning, afternoon, night).
• The dependent variable depends on the independent variable. Here, the scientist measures weight loss, which depends on when the mice run (while caloric intake is constant). So weight loss is the dependent variable.

Answer:

C) Latitude
