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.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
