Answer:
D) not swim in or drink the water from the stream
Explanation:
Low pH means the water is acidic which is harmful to your skin as it can cause burns and irritations. So any means of contacting with water is not healthy. The damage to the skin happens as in acidic water it has more H+ than in the neutral water and the extra H+ ions can ionize the atoms which are combined to form different compounds in the skin when in contact.

The apple in my hand has three different forms of energy
that I can think of.
1). Thermal energy. I know that the apple's temperature is
not absolute zero, because it is not freezing my hand off.
Therefore it holds some heat energy.
2). Chemical energy. From previous experience, I know that
if I eat the apple, it gives me a boost and keeps the doctor away,
since my body is able to metabolize it, and extract nutrition from
its chemical energy.
3). Potential energy. Also from previous experience, I realize
that when I picked up the apple, I exerted force on it opposite to
the force of gravity. By doing work on it, I endowed it with increased
gravitational potential energy, which would immediately be obvious
if I dropped it to the ground, where it would either smash or dig a
little crater in the grass.
