Emily enjoys experimenting with color changing lizards. she places a green lizard on a brown background and a brown lizard on a green background. emily knows the green lizard should turn brown and the brown lizard should turn green. neither lizard changes color. which is what may have caused emily's results? a. other factors may be affecting the color change like fear or temperature. b. the lizards had to choose to move to the new background for the effect to take place. c. more time should be allotted to allow for the color change to take place. d. the backgrounds may have been the wrong shade of color for these specific lizards.

A. Other factors may be affecting the color change like fear or temperature.

Explanation:

The main problem with the lizards not changing colours could be due to fear or temperature, changing colours doesn´t happen because the lizard chooses to move to the new background, nor the time affects the changing of the colour, and the shade of the background doesn´t have anything to do with the ability of the lizard to change colours, so it must have to be with fear, or temperature, maybe the lizard fears that Emily might be a predator and that is why he doesn´t change colours.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
