Answer:
Explanation: ground water contamination is nearly
always the result of human activity. In
areas where population density is high and human
use of the land is intensive, ground water is especially vulnerable. Virtually any activity whereby
chemicals or wastes may be released to the environment, either intentionally or accidentally, has
the potential to pollute ground water. When
ground water becomes contaminated, it is difficult
and expensive to clean up.
To begin to address pollution prevention or remediation, we must understand how surface waters
and ground waters interrelate.
Blindness is one long term side effect
A. The work increases.
Work=Force*Distance
in this case, the force is the weight since we are moving in an upward direction.
Weight=Mass*Acceleration Due to Gravity
Since Gabriella is carrying a greater mass upward (herself and the two heavy books), her force upward is greater in the second case. Thus, since the distance is the same, the work done by Gabriella is also greater.

3. The spleen serves as a place to storage white blood cells, red blood cells, platelets and antibodies.
4. The spleen is a very sensitive organ in that it detects the presence of any infection in the body and this in turn cause it to produce white blood cells that are necessary to fights of the infection from bacteria, viruses e.t.c , thereby protecting the immune system of the body.
