2 Which procedure will determine if water temperature affects the weathering of sedimentary rocks?
A. Test 3 identical sedimentary rocks, 1 each in 3 different water temperatures.
B. Test 3 identical sedimentary rocks in 1 water temperature.
C. Test 1 crushed sedimentary rock and 1 whole sedimentary rock in water.
D. Test 3 identical sedimentary rocks, 1 each in acid, 1 in a base, and 1 in water.

The correct option is A

Explanation:

To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).

Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.

This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.

youre right there are

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
