Keera decided to investigate how the growth of plants is affected by the time of day it is watered. she placed an equal amount of potting soil in three identical pots and planted three bean plants in each pot. the pots were placed on the same table so that they received the same amount of light. one pot was watered at sunrise, one at noon, and the last pot at sunset. after ten days, the height of each individual plant was measured and recorded. what is the independent variable in this investigation?

Which of these is a physical property

The image compares the arrangement of electrons in two different neutral atoms. a figure labeled atom q has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has six black spheres. to the left of this figure is another figure labeled atom p. atom p has a shaded sphere at the center of three concentric circles. the innermost circle has two black spheres. the middle circle has seven black spheres. which of the following best explains the position of the two atoms in the periodic table? atom p has an estimated zeff of 7 and is therefore to the left of atom q, which has a zeff of 6. atom p has an estimated zeff of 7 and is therefore to the right of atom q, which has a zeff of 6. atom p has an estimated zeff of 5 and is therefore below atom q, which has a zeff of 4. atom p has an estimated zeff of 5 and is therefore above atom q, which has a zeff of 4.
