The analysis of water in a lake or stream depends upon more than one field of science or body of
knowledge. suppose you stumble across a portable water-testing lab on a riverbank, and you find two
testing stations: (1) a package of ph (acid/base) test strips and a digital thermometer, and (2) a light
microscope and glass slides. but you find no scientists.

Very hard to understand

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
