# science i reall need help i am stuggling

Sue is setting up an experiment to test whether fly maggots select a dark or a brightly lit environment. She sets up a chamber in which there is a gradient in light intensity from one end (dark) to the other (brightly lit).

The experimental hypothesis was “There will be a large difference between the number of maggots in a dark environment and the number in a brightly illuminated one.”

Which of the following is Sue’s Experimental condition? Select one option from the list below.

1) The same chamber and maggots but with a different light intensity gradient.

2 ) The same chamber and maggots but with a coloured light gradient.

3 ) An identical chamber with the gradient in illumination reversed. wrong answer

4) An identical chamber but with maggots of a different species.

5) An identical chamber with no light gradient.

6) A chamber with a different distance between the darkest and most brightly lit parts.

7) An experiment at a different time of day.

is 4 the correct answer plz someone help me and tell me the correct answer

science i really really need help
The number of maggots, n, is a function of (or "depends on") light intensity, i. n = f(i) i is the independent variable and n is the dependent variable. In other words n depends on i.

Which do you think after reading that carefully? Number of maggots DEPENDS ON light intensity.
Thursday, December 12, 2013 at 1:01pm by Damon

science i really really need help
Therefore light intensity is independent and number of maggots is dependent.
