Turtles are cold blooded, meaning they use the Sun to keep warm. A student hypothesizes that his pet turtle will prefer swimming in warm water. He places his turtle on a rock in the middle of the bathtub, and measures how much time the turtle spends off of the rock during a five minute period. He conducts the experiment under four conditions in the bathtub: no water, warm water, cool water , and room temperature water. In this experiment, which is the control group ?

Room temperature water

Explanation:

Neither the amount of water nor the temperature of the water has been changed.

its first and third is your answer i did the qustion the fourth isnt right

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
